Top 10 Manufacturers Of PVC Soft Film Slitter China 2026

 

 

B2B Sourcing Guide · 2026

A procurement review of ten Chinese builders of PVC soft film slitting and rewinding equipment - covering micro-tension architecture, plasticiser-driven tack and blocking behaviour, static management, slitting method selection, and the acceptance tests that decide whether a soft-film line holds its width tolerance from the first metre to the last.

How to Read This PVC Soft Film Slitter Sourcing Guide

 

Practical note for buyers: on a PVC soft film slitter the binding constraint is never the delivery date. It is the material trial. Ask each shortlisted supplier to run your own film - both faces, at your target line speed, on your intended slitting method - and then to hold the finished rolls for seventy-two hours before you inspect them. Width tolerance is easy to demonstrate. Blocking, telescoping and edge creep only show up after the roll has sat. A supplier who will not agree to that test is telling you something useful.

In No Particular Order

 

The ten manufacturers below are presented without ranking. Sequence reflects the order in which the profiles were compiled, not performance. Match the machine class, the tension architecture and the winding concept to your own film thickness, plasticiser load and downstream process before you compare price.

 

Dadu Intelligent Equipment Co., Ltd., registered as Zhejiang Dadu Intelligent Equipment Co., Ltd., builds slitting and rewinding equipment out of Zhejiang and has spent two decades in the slitting field with its core team recruited from established equipment makers in the same industry. The company runs its commercial and engineering operation from Hangzhou and its manufacturing floor in Wenzhou, and positions itself in the mid-to-high end of the category rather than competing on price. Its range is organised into two distinct families - the Independent Station Slitter Rewinder and the Non-stop Slitter Rewinder - and the application, not the catalogue, decides which architecture a buyer should specify.

For PVC soft film the relevant platform is the PVC Soft Film Slitter, offered as the ATFQ-1300 and ATFQ-1600. Unwind widths are 1,300 mm and 1,600 mm against a maximum unwind diameter of 1,200 mm. Slitting width range runs from 25 mm up to 1,250 mm on the smaller model and up to 1,550 mm on the larger one, which means the same machine can produce narrow wrap bands and full-width master rolls without a knife reconfiguration that costs a shift. Available material thickness is quoted as plastic films from 12 to 100 micrometres and paper from 30 to 200 gsm, covering cling film, soft packaging film and light laminates on one platform. Maximum slitting speed is 600 MPM on a 380 V / 50 Hz supply drawing 45 to 80 kW. The ATFQ-1300 occupies 5,000 by 3,500 by 2,500 mm at 13.8 tonnes; the ATFQ-1600 measures 5,000 by 3,800 by 2,500 mm at 14.8 tonnes.

The non-stop architecture is the part that matters most on plasticised film. A dual turret carries four winding shafts: two run at full production speed while the other two complete paper core mounting, finished roll discharge and pre-production set-up in parallel. A servo turret positioning system completes the automatic reel change within seconds, and an automatic cutting function severs the web without an operator leaning into the machine. Dadu states this arrangement lifts overall output by more than 40 percent against a conventional single-turret slitter, and the secondary benefit on PVC is arguably more valuable than the throughput: every manual intervention on a tacky, extensible web introduces a tension disturbance and a handling risk, and the non-stop layout removes almost all of them from the production cycle.

Cutting accuracy is held within plus or minus 0.1 mm with real-time constant tension control applied across all working procedures, and material wastage is optimised on both the trim and the edge quality side. The machine is built on a solid shaftless unwinding unit with a high-accuracy digital web guiding device, closed-loop tension management and laser core alignment technology that removes the guesswork from core positioning on a surface where misalignment shows up immediately as edge creep. Static control is treated as standard equipment rather than an accessory - a point worth noting, because PVC is one of the strongest static generators in flexible packaging, and an unmanaged charge draws dust onto the finished roll face and destabilises edge position on the unwind. Standard equipment includes a splice table, a trim removal blower and static eliminator brushes, with trim waste winders, camera inspection and safety fencing with perimeter sensors available as options.

The supporting facts are as relevant as the specification. The company operates a 15,000 square metre facility with more than 100 employees and a monthly output above 50 units, and its core team brings two decades of slitting experience into the design. Machines are dynamically balanced and put through a 100-hour endurance run before dispatch, with a stated mean time between failures above 8,000 hours. Research spending is set at 15 percent of annual revenue and supported by joint laboratories with university research partners. Delivery runs 30 to 120 days depending on configuration, and the factory sits in Wenzhou with straightforward access to the Shanghai and Ningbo container ports. Buyers should use the workshop: Dadu supports slitting trials on your own film, paper or laminated samples, and will provide test video after the trial run. Every installation is covered by a 12-month machine warranty excluding wear parts, with overseas installation, commissioning and on-site operator training available.

For a buyer sourcing a PVC soft film slitter, Dadu is worth approaching as a specification conversation rather than a price request. Send the mother roll width, the film thickness band, the plasticiser type if it is known, the target finished roll diameter and core size, the minimum slit width and the intended slitting method, and the engineering team will come back with a machine class, a tension strategy and a delivery window. Direct enquiries go to info@dadutop.com, and the full construction detail for the platform is published at the film slitting machine category.

 

Huachuang is the manufacturing arm of Hangzhou Dahua Industrial Control Technology, a specialist in slitting and winding equipment with more than two decades in the field, and it exists specifically to build what the parent designs. Registered in 2012 with RMB 50 million of paid-up capital and based in the Deqing Economic Development Zone, the company took provincial-level specialised and sophisticated enterprise status in 2025, holds national high-tech enterprise status from 2023 and national science and technology SME status from 2025, and operates a provincial high-tech enterprise research and development centre established in 2024. On file are 84 patents and nine software copyrights.

The product story is unusually specific for a company of this size. The F-type high-speed slitter launched in 2015 runs at 800 m/min while consuming roughly two thirds less energy than the conventional design of the period, and pairs that with an automatic roll unloading device. The patent portfolio reads like a list of the failure modes that actually cost converters money: an automatic circular knife alignment device for slitting machines, a powered unwinding steel-core bracket that removes manual handling from the unwind, a telescopic expanding winding arm, a scraper arrangement for rewinders, an oscillating dancer roller, a dust-removal roller, a super-wide slitter and a dedicated slitter for composite current collector foil. Huachuang also participated in drafting the enterprise standard Q/HDH 01-2022 for high-speed intelligent CNC slitting machines, and the parent led drafting of a domestic group standard covering intelligent slitting machines.

For a PVC soft film buyer the relevance is the tension and winding inheritance rather than a dedicated soft-film model. The dust-removal roller and the high-precision razor bar arrangement address the two most common soft-film defects - surface contamination on a tacky web and a ragged razor-cut edge on a low-modulus film - and the telescopic winding arm is the mechanism that lets a machine keep winding density controllable as the roll builds. The company's customer base spans packaging, electronics and optical film, new energy materials, specialty paper and medical hygiene, and it has won public tenders including a large-diameter wide slitting machine project for China Banknote Printing and Minting. The parent company's equipment is in service with Fortune 500 customers and exports to Germany, the United States and Japan, which is a useful proxy for whether a supplier can hold tolerance on demanding substrates. Buyers should treat Huachuang as a route to a technically deep platform with a shorter order book than the large film-line builders, and should confirm the tension range and the minimum slit width against their specific plasticised film before signing.

 

Huayang is the largest engineering organisation on this list and the only wholly state-owned one. Founded in 1999 and part of the China Aerospace Science and Technology Corporation group through Xi'an Aerospace Engine and Xi'an Aerospace Science and Technology Industry, it operates on RMB 96.43 million of fully paid capital with 775 employees, roughly 60,000 square metres of built area and about 41,000 square metres of workshop space. The company runs through ten independently accounted business divisions and keeps a research and development centre of more than 120 engineers. It holds more than 260 national patents together with more than ten national high-tech achievement awards, and has been recognised as a national specialised and sophisticated little giant, a national key little giant and a Shaanxi provincial manufacturing single champion in the precision coating equipment category.

The technical reason Huayang belongs in a PVC soft film review is its core technology group. The company's stated competencies include coupled modelling and decoupling control of tension systems, intelligent equipment control, precision coating and lamination, curing and solvent residue control, and multi-material winding adaptability. Decoupling control of tension is precisely the discipline a plasticised PVC web demands: on an elastic, low-modulus film the tension at the slitting point, the tension entering the rewind and the tension generated by the guide correction all interact, and a control system that treats them as one loop will oscillate. Huayang built its reputation on exactly that problem in film and foil processing, and it holds a national Science and Technology Progress Award and a Shaanxi provincial Science and Technology Progress Award for printing, laminating and slitting equipment developed for medical protective product manufacturing.

Product lines cover CI flexographic presses, rotogravure presses, decorative material production lines, precision coating equipment, new energy and new material lines, water treatment membrane lines and intelligent production lines. Two of those are directly relevant here. The decorative material equipment division builds lines for PVC-based decorative film, so the company already understands how plasticised PVC behaves as a web rather than as a theoretical substrate. The precision coating lines include unwind, coating, drying, cooling and rewind sections with slitting and trim handling, which is where their web-handling competence is exercised in production rather than on a specification sheet. Quality management is certified to ISO 9001:2015 with SGS and EU CE safety certification. The trade-off for international buyers is straightforward: this is a project-scale organisation, so lead times and minimum order values will not suit a converter buying a single 1,300 mm machine, but for a buyer planning a soft PVC film line with an integrated slitting section, it is one of the few Chinese suppliers whose engineering depth is verifiable at the corporate record level.

 

Huabao approaches PVC soft film from the other end of the process. Founded in 1998 and part of the Hebei Huabao Plastic Machinery group, with operations traced back to the mid 1980s, the company designs and builds cast film extrusion lines rather than standalone slitters. That matters because on a PVC cast line the winding and trimming section is where roll quality is decided, and the film recipe that governs tack, blocking and creep is set a few metres upstream in the same building. The company runs a 244-person operation in Xinle, Shijiazhuang, holds 71 patents, has served as leading drafter on two industry standards, and works to ISO 9001, ISO 14001 and EU CE certification. It has been designated the national base for plastic cast film machinery research, development and manufacturing, and has been repeatedly ranked among China's top five plastic extrusion machinery enterprises.

The PVC-relevant product range is substantial: PVC cling film lines, PVC high-clarity packaging film lines, PE cling film lines, PE embossed and breathable film lines, CPE transparent and laminating base film lines, PVDF fluoropolymer lines, PBT and PMMA rainbow film lines, EVA and POE photovoltaic encapsulant lines, TPU cast film and sheet lines, PP, PE and PS sheet lines, and PVC mesh composite lines for acoustic and tarpaulin applications. The winding milestones track the same problem a slitter buyer is trying to solve: in 2004 the company developed a three-shaft automatic winder for PE and PVC cast cling film with film width to 2,000 mm and exported an ultra-wide 3,000 mm PVC cling film line to Korea; in 2017 it delivered China's first 3,000 mm double-four-shaft eight-station winder; in 2018 it delivered a 2,000 mm double-four-shaft eight-station line with a design line speed above 1,000 m/min; and in 2019 it developed a 4,000 mm CPP cast film line.

Overseas business is close to half of turnover, with equipment running in more than 60 countries and service outlets established in the regions where installed density is highest. For a buyer whose requirement is a slitting and rewinding module that has to match a specific PVC film recipe, that combination is the argument: Huabao can discuss the plasticiser system, the anti-block additive package and the film's relaxation behaviour as variables in the same conversation as the winder design. This is not a company to approach for a generic 1,600 mm converting slitter, and it will say so. It is the right approach when you are specifying slitting and trim handling as part of a soft PVC film line, or when the film you need to slit has a surface behaviour that a general-purpose slitter has already failed to manage.

 

Sanxin has been building plastics processing equipment since 1995, was incorporated as a joint stock company, and has been listed on the National Equities Exchange and Quotations market since April 2015 under ticker 832301, which means its disclosures are public and its accounts are externally reviewed. The company operates from Qidong in Nantong, Jiangsu on a 22,000 square metre site with 114 employees on the corporate register, RMB 22.09 million of registered capital and national high-tech enterprise status. It has carried multiple national Torch Programme, innovation fund and provincial science and technology support projects, and holds 57 valid patents of which 51 are granted and 30 are invention grants.

Two of the company's three main product lines bear directly on PVC soft film handling. The cast film line business covers PE and PVC cast film including PVC cling film, with patents covering a dual-vacuum hopper feeding device for PVC cast cling film, a fully automatic distributor for multi-function cast co-extrusion film, a sandwich film forming machine and an automatic roll transfer mechanism. That last item is the winding-side competence a slitter buyer should care about: automatic roll transfer on a tacky film is a handling problem before it is a control problem, and a supplier that has had to solve it on its own extrusion lines has solved it under production pressure. The surface treatment business covers corona treaters across ten series and more than one hundred models, applicable to plastic films, metallised film, aluminium foil and coated substrates, which is relevant because PVC soft film is frequently corona treated inline to make it printable or laminable, and treating immediately before slitting changes the web's surface energy and friction behaviour on the guide rollers.

Equipment has been exported to the United States, Russia, Canada, Japan, India and Australia, and the company holds ISO 9001 certification with an in-house research laboratory. For buyers, Sanxin is the sensible shortlist entry when PVC soft film slitting is one station in a wider film production or converting project, when corona treatment and slitting must be specified together, or when the buyer wants a supplier whose financial and production records can be checked through a regulated disclosure channel rather than through trade directories. The company is also a useful benchmark in negotiations: a listed supplier's published capacity figures give a buyer a realistic reference point for what a genuine Chinese cast film equipment manufacturer looks like in terms of plant, staff and patent depth.

 

Tide has done one thing since 2005, when its first MS400 slitter was built, and the company's published development record is a sequence of machines rather than a marketing narrative. HS400 and the ER300 inspection machine followed in 2006, the SR400 rewinder and KS600 in 2007, the LS500 high-end slitter in 2008, an economy ES300 in 2009, then the MR300 and SR500, then a slitter and a rewinder for liquid packaging board in 2011 and 2012. Servo drive was rolled across the whole range in 2013. In 2014 the company developed the DS400 micro-tension slitter, and in 2015 the SP600 for high-tension paper and board. The pattern is that Tide built the tension range from both ends, which is why the platform fits plasticised film better than a general-purpose slitter would suggest.

The registered entity sits in Deqing County, Huzhou, Zhejiang with RMB 7 million of fully paid capital and around fifty employees, and the company trades as DEQING TIDE MACHINERY CO., LTD. with the TIDE TECHNOLOGY brand. It has exhibited at drupa, holds ISO 9001, CE and EHS certification, and counts central state-owned enterprises, listed companies, national little giant enterprises and provincial manufacturing single champions among its customers. Current production covers the LS800, SP600 and KS600 series of digital-control high-speed slitters together with high-speed rewinders and inspection machines.

The construction detail is where the soft-film capability lives. Slitting is by razor with a high-precision blade arrangement, material is loaded by motorised lead screw rather than by hand, unwind width is adjusted by motor, winding is centre-type with differential shafts, and tension is managed in zones rather than as a single loop, with follow-up winding and a dancer roller controlling the transition as the roll builds. Each winding station carries its own discharge trolley, chucks are shaftless, and the machine self-diagnoses with maintenance prompts. Laser core positioning is fitted for core alignment, and the splice table carries a cutter and pneumatic hold-down. For a buyer running plasticised PVC, the combination of zoned tension control, motorised unwind width adjustment and laser core positioning is close to the ideal starting specification: the first two keep a low-modulus web from being stretched between stations, and the third removes the single most common cause of edge creep on a tacky film, which is a core fitted slightly out of position by hand while the web is live.

 

Xinwang has been building coating and slitting equipment since 1998, was registered as a company in 2003, and holds RMB 20 million of fully paid capital. The company owns more than 18,000 square metres of plant and office space in Dongguan, employs a management and engineering team of over eighty people, holds 48 national patents, and has run an ERP system since 2016. It is a national high-tech enterprise certified to ISO 9001:2015, maintains a long-running research cooperation with Huazhong University of Science and Technology, and has acquired a 63 mu industrial site for a planned precision equipment and high-performance film materials industrial park covering roughly 120,000 square metres of built area.

The slitting range is deep and deliberately segmented. The 221 series covers general slitting, the 802 series combines laminating with slitting, and the 808 series is a centre-and-surface slitter - the winding concept that matters most on soft, tacky PVC, because it separates the tension that controls winding hardness from the tension that controls web flatness. Beyond those, the company builds BOPP series slitters, precision slitters for adhesive label stock, machines for fax and thermal transfer paper, precision slitters for optical film, fully automatic slitters, fully automatic rewinders, automatic cutting tables and automatic paper tube cutters. On the coating side it supplies machines for optical film, automotive and electronic tape, and specifically for soft PE and PVC substrates, which is the point of interest for this review: Xinwang builds both the coating machine and the slitting machine for the same film family, and a supplier that has had to coat a plasticised PVC web has already dealt with its solvent sensitivity, its stretch under drag and its tendency to stick to anything it touches.

Commercial reach is broad. The company reports more than four thousand customers and exports to around eighty countries and regions, with materials equipment covering eighteen major categories and more than six hundred models. It also builds edge trim handling into its slitting lines, which is a practical advantage on soft PVC because a plasticised trim strip is difficult to convey pneumatically without stretching or wrapping. For a buyer who runs coated or laminated PVC soft film and wants a single supplier for both the coating and the slitting operation, Xinwang is the natural shortlist entry, and its centre-and-surface winding design deserves specific attention from anyone fighting blocking on finished rolls.

 

Heng Huilong builds converting lines for roll goods and has built its reputation in the substrates that punish a machine hardest: medical and hygiene materials, air filtration media, waterproof membranes and medical tape. Those are elastic, low-basis-weight webs that deform under load, which is the same engineering problem plasticised PVC presents. The company was founded in 2010 with RMB 5 million of fully paid capital, operates from Shunde in Foshan, and holds national high-tech enterprise status granted in 2023, Guangdong provincial specialised and sophisticated enterprise status from 2022, provincial innovative enterprise status, national science and technology SME status renewed in 2026, and ISO 9001:2015 certification with a measurement management system on top. Its patent position is 7 granted inventions and 28 granted utility models.

The product portfolio centres on roll-goods coating, slitting and rewinding lines, high-speed laminating lines and winding systems, supported by a wider range of hot-melt adhesive coating and laminating machines and automated handling equipment. The most instructive reference on the company's record is a 2.6 metre wide coating machine for TPU film and nonwoven that holds laminating accuracy within 0.01 mm while running an elastic substrate, and which carries the company's own manufacturing execution system. Holding that tolerance on a web that stretches is a tension control achievement, and it says more about a supplier's competence than a catalogue of model numbers would. The company also founded a separate automation business in 2018 covering automated storage and retrieval, guided vehicles, labelling, sorting and robotic palletising, which means finished roll handling can be automated as part of the same project.

Applications listed by the company include packaging, labels, hygiene products, waterproofing membrane, air filtration and medical materials, all of which share the characteristics that make PVC soft film difficult: low modulus, high surface friction and a need for controlled winding hardness. For a converter slitting soft PVC film for medical, hygiene or protective applications, Heng Huilong is worth a trial run, and the trial should focus on the winding system rather than the knife, because that is where the company's engineering investment has gone. Buyers should also confirm the machine's maximum unwind capacity and frame class against their own mother roll, since the company's core market is roll goods converting rather than wide-web film production.

 

Hongfeng's engineering lineage runs back to 1995, when the predecessor Foshan Hongfeng Hardware Factory began building film machinery; the first slitter came in 1997, a cold-strand film pelletiser was patented in 1998, and the current company was registered in 2008 with RMB 2 million of fully paid capital on a site in Nanhai, Foshan. It holds national high-tech enterprise status, ISO 9001:2000 and EU CE certification, and about 34 patents plus a software copyright, and it invented the cold-strand plastic film recycling machine that the company's export business was originally built on.

What makes Hongfeng unusually easy to evaluate is that its model literature names the substrates. The HFQD-F high-speed computerised large-roll slitter is specified for BOPP, BOPA, PET, CPP, CPP-aluminium, PET-aluminium, PP, PE and PVC plastic films, laminates and metallised films. The HFQD-FU slitter-rewinder puts unwind and rewind on the same side for small-diameter film rolls in a compact frame. The HFQD-CB high-speed micro-tension machine is specified for breathable film and for PE, TPU, BOPP, BOPA, PET, CPP and PVC, which makes it the most directly relevant model for anyone slitting thin plasticised soft film. Alongside those sit a four-shaft automatic roll change slitter for optical and PCB film, an independent-arm slitter for lithium battery separator film, and computerised machines for wet and dry process separator micro-tension slitting.

The company also builds the auxiliary equipment that soft film converting usually needs and that buyers forget to ask about: film edge trim traction units, edge winding units, film rewinders, inspection machines and hot-melt adhesive coating and laminating machines. On plasticised PVC a trim strip is stretchy and difficult to convey, so a supplier that already sells a dedicated edge trim traction and winding system has a practical answer to a problem that otherwise gets solved with a waste bin and an operator. Equipment is exported to between 42 and 48 countries including the European Union, the United States and Japan. This is a focused, comparatively small manufacturer rather than a heavy industrial group, and it is the right shortlist entry for a converter who wants a machine specified around a named substrate and a micro-tension requirement rather than a general-purpose platform.

 

Kesheng began as a machining operation in 2002 and was incorporated as a company in 2006 with RMB 5 million of registered capital, of which 4.74 million is paid up. The company is based in Jiangyin, Wuxi, in Jiangsu, holds national science and technology SME status, and describes itself simply as a slitting machine manufacturer serving flexible packaging. What distinguishes it from the many small workshops in the same region is capital intensity: it has invested around RMB 70 million in domestic and imported machining equipment and operates a 20,000 square metre production and research workshop alongside a 15,000 square metre showroom and office building.

The product line covers slitters, rewinders, inspection machines, coding platforms and offline inspection systems, and the company states that its machines are applied in optical film and solar backsheet film, both of which are mid-to-high-end slitting applications that demand tight width tolerance, flat wound rolls and low edge dust. That discipline transfers: a supplier who can hold tolerance on thin optical film has the measurement equipment and the process control to hold it on plasticised PVC, where the challenge is different but the metrology is the same. Equipment is distributed across more than thirty provinces and cities in China and into Southeast Asia.

Kesheng suits a specific buyer profile. If the requirement is a configurable machine in the 1,300 to 1,600 mm class, the film mix is modest and the volumes do not justify a wide-web platform, a focused specialist with its own machining capacity is often a better commercial fit than a large group, and the inspection and coding equipment in the same catalogue means slit rolls can be checked and marked in one workflow. Buyers should verify the tension range against their lightest film, since a machine tooled for optical film is normally specified at much higher tension than a cling film application needs, and should confirm the rewind concept in writing. Ask for the machine's behaviour at the thin end of the range, not at the top of it.
