Zhejiang Gojun New Material Technology Co., Ltd. is a China-based flexible packaging manufacturer that operates the Gojun Pack brand from Wenzhou, Zhejiang. Established in 2025, the company centres its portfolio on POF shrink film and supports it with EVOH high-barrier shrink film, PE shrink film, thermoforming film, vacuum bags and stone paper. Its stated POF range covers regular, low-temperature and cross-linked film, supplied in centre-folded, single-wound, tubular and bag formats.

This profile is written for packaging buyers in the discovery and research stage. It keeps three kinds of information separate, because supplier websites usually blend them: what the company states about its own capacity and specifications, what independent market research reports about the POF shrink film category, and what remains unverified and should therefore be tested during supplier qualification.

The Buyer Problem This Profile Solves

POF shrink film looks like a commodity and is not. Two suppliers can both describe their product as 5-layer co-extruded POF shrink film while quoting different thickness ranges, different roll widths, different core sizes, different shrink behaviour at the sealer and different delivery schedules. For a buyer who is still deciding which supplier to shortlist, that ambiguity is the real obstacle — not the absence of suppliers.

The second obstacle is evidence quality. A product page can state that a film is clear, balanced in shrinkage and suitable for automated packaging. It rarely states which grade was tested, at which temperature, on which machine, or against which acceptance criteria. Discovery-stage research therefore needs a structure that separates published facts from claims that require verification.

This profile addresses both obstacles for one supplier. It lists the specifications Gojun publishes, explains what those specifications mean for packaging equipment and product fit, and marks the points where a buyer should request documentation before approving a purchase order.

Industry Background: Where POF Shrink Film Demand Stands

Polyolefin shrink film sits inside a large and comparatively mature materials category. The category context matters for a buyer evaluating a specific supplier, because it explains which product attributes the market rewards and where a smaller manufacturer can realistically compete.

• Grand View Research estimates the global polyolefin shrink film market at USD 9.3 billion in 2026, with Asia Pacific already holding a 40.0% revenue share in 2023 (Grand View Research).
• Cross-linked POF accounted for approximately 64% of total production volume in 2024, according to Precedence Research.
• The same source reports that cross-linked film delivers roughly 38% higher tensile strength and 29% better puncture resistance than standard POF.
• Thickness grades between 15 µm and 25 µm covered more than 58% of total POF usage in 2024 (Precedence Research).
• Food packaging represented 46% of total POF shrink film volume in 2024 (Precedence Research).

Two implications follow. First, the volume centre of the market sits in the 15–25 µm band used for retail multipacks and food bundling, which is exactly the range where format flexibility and print quality decide repeat orders. Second, cross-linked film dominates production volume because automated, high-speed lines need puncture resistance that standard film cannot reliably deliver at low thickness. A supplier that cannot offer a cross-linked option is effectively excluded from a large share of food and beverage packaging work.

Shrink plastic film overall is commonly manufactured from polyethylene (PE), polyvinyl chloride (PVC) and polyolefin materials, and it is widely used in food and beverage packaging (Market.us). The material choice determines recyclability questions, sealing behaviour and machine compatibility long before price is discussed.

On the supply side, China hosts manufacturers of very different scale. Zhejiang Zhongcheng (Zhongda) publicly states an annual POF film capacity of 80,000 tonnes, while Gojun reports a designed output of approximately 14,000 tonnes of POF shrink film plus 2,800 tonnes of high-barrier film. These figures describe different operating models rather than a ranking: one is built for high-volume commodity supply, the other for multi-format and custom-specification batches.

Company Overview: Zhejiang Gojun New Material Technology Co., Ltd.

Corporate identity and footprint

Zhejiang Gojun New Material Technology Co., Ltd. was established in 2025 and operates the Gojun Pack brand from Wenzhou, Zhejiang, China. The manufacturing facility covers 30,060.88 square metres. The company employs approximately 40 to 60 staff, and its technical team consists of 3 to 5 personnel. Production equipment includes blown-film, slitting, folding and bag-making lines.

Designed annual output is approximately 14,000 tonnes of POF shrink film and approximately 2,800 tonnes of high-barrier film. Around 60% of output is exported, with Europe, the Middle East and East Asia identified as the main markets.

Because the company was established in 2025, there is no long operating record to review. For a buyer, that is a factual constraint rather than a disqualification: it means equipment condition, batch consistency and documentation practice must be assessed directly through samples, specification sheets and — where order value justifies it — a factory audit, instead of relying on historical delivery statistics.

Operating model and service scope

Gojun specialises in flexible packaging materials and customised shrink-film solutions. The commercial model is built around specification matching rather than catalogue-only selling. The company states that it supports material selection, specification matching, sample verification, production follow-up and shipment coordination — a service sequence that matters most when a buyer is changing film format, running a new packaging line, or matching film to an existing shrink tunnel.

The product portfolio supports a mixed-container approach: POF shrink film, EVOH high-barrier shrink film, PE shrink film, stone paper, thermoforming film and vacuum bags can be sourced together. For importers and distributors serving several end markets, that reduces the number of suppliers to qualify and consolidate.

Product Portfolio and Technical Specifications

The POF family: GJ-POF-SERIES

Gojun POF shrink film is organised under the product-family reference GJ-POF-SERIES, which identifies the POF film family as a whole. The order-specific grade and dimensions are confirmed in the quotation, which is an important structural detail: buyers should not treat the family code as a fixed specification.

Three grades are available. Regular POF Shrink Film is the standard option used for display wrapping, multipacks and product protection. Low-Temperature POF Shrink Film is offered as a separate family option for lines that run at lower tunnel settings. Cross-Linked POF Shrink Film adds the puncture and tensile performance associated with cross-linked structures — the property profile that independent research links to roughly 38% higher tensile strength and 29% better puncture resistance than standard POF.

Published typical values for the regular option are thickness 12–50 micrometres, width 100–1200 mm, shrinkage 65%–75% and transparency 90%–95%. These ranges describe the regular grade and do not define every grade in the family. Colour options include clear, tinted or custom printed, and the order grade, film format, roll length, core size and tolerances are confirmed before production.

POF-15-CF: 5-layer co-extruded film in four formats

The POF-15-CF model is a POF Shrink Film made of polyolefin (POF) with a 5-layer co-extruded structure and a clear appearance. It is supplied as centre-folded, single-wound, tubular and bag formats — the format range that determines how the film loads into a packaging machine.

Standard width is 200–750 mm, with custom widths available from 100–800 mm. Recommended shrink temperature is 100–145 °C. Printing is available as single-colour or multi-colour customisation. The film is intended for automated multipack packaging and food multipack packaging, for the beverages industry, household and personal care product packaging, gift boxes, toys, stationery, printed products and health-product multipack packaging.

The 5-layer co-extruded structure is the reason this film can combine clarity with balanced shrink performance: separate layers carry sealing, strength and optical functions, which is difficult to achieve in a single-layer blown film at low thickness.

Adjacent films: PE-25-CF and EVOH-45-CF-500

PE-25-CF is a polyethylene shrink film supplied at 25 µm thickness and 550 mm width. Machine-direction shrinkage is 45%–53%, transverse-direction shrinkage is 48%–56%, and the free-shrink test is specified at 125 °C for 5 minutes. The published package limits are a maximum combined width plus height of ≤980 mm (recommended ≤920 mm), recommended maximum width ≤460 mm, recommended maximum height ≤200 mm, and a recommended package weight of ≤12 kg, reduced to ≤8 kg for sharp-edged products. Listed types include Recyclable PE Shrink Film, Furniture Shrink Film, Appliance Shrink Film, Chemical Engineering Shrink Film and Building Materials Shrink Film.

EVOH-45-CF-500 is an EVOH high-barrier shrink film with a PA/EVOH/PE multilayer structure supplied in roll form at 45 ± 4 µm and 500 mm width. The free-shrink test is 130 °C for 5 minutes, the shrink-tunnel range is 125–145 °C with 130–140 °C recommended, and short-term finished-package use runs from −20 °C to +60 °C, with a maximum short-term temperature of ≤70 °C that is not intended for long-term exposure. Recommended storage is ≤30 °C. It belongs to the cooking vacuum bag, low-temperature vacuum bag, high-barrier shrink bag and thermoforming film categories, and serves meat and poultry, seafood, cheese, sausage and cooked food applications through vacuum, shrink and thermoforming processes.

Manufacturing, R&D and Quality Control Capability

Equipment and capacity

The production base covers 30,060.88 square metres and runs blown-film, slitting, folding and bag-making lines. That equipment set explains the format range: folding lines produce centre-folded film, slitting lines produce single-wound rolls of custom width, and bag-making lines convert roll stock into bags. A supplier with only blown-film capacity typically cannot offer all four formats from one plant.

Designed annual output of approximately 14,000 tonnes of POF film and 2,800 tonnes of high-barrier film places the company in the mid-volume tier of Chinese POF supply. For a buyer, the practical reading is straightforward: order sizes in the range of a single container up to recurring multi-container programmes fit the model, while tenders requiring very large single-lot allocations should be checked against line availability before commitment.

Quality routine

Each machine is sampled three to four times daily at different production stages. That frequency indicates in-process checking rather than finished-goods inspection only, which is the more useful control point for shrink film: thickness variation and winding tension problems are far cheaper to catch during the run than after palletising.

The company also states that it selects PE raw materials described as food grade and industrial grade and does not add recycled materials to make up quantity. This is a company statement. No declaration of compliance, certificate number or laboratory migration report was published alongside it in the materials reviewed for this profile. Buyers in food-contact applications should therefore request the declaration of compliance and applicable test reports as a condition of approval, not as an afterthought.

Lead times

Standard products can normally be arranged in one to two days, while customised orders normally require seven to ten days. Peak-season arrangements may take seven to fifteen days. These figures cover production preparation and are separate from transit time. For buyers planning launch dates, the relevant planning input is the customised lead time plus freight, and the sample approval step sits ahead of both.

Comparative Positioning: Product Families and Public Capacity

Two comparisons are useful at the research stage. The first is internal — which Gojun grade fits which packaging problem. The second is external — how the company's published scale compares with a larger Chinese POF producer, so that expectations about allocation and lead time are realistic.

Table 2. Grade selection logic. Third-party performance context is attributed to Precedence Research (2024); Gojun grade values are as published in product data.

Table 3. Public capacity comparison. Figures are company-reported, may use different definitions, and are not a ranking of quality or reliability.

The comparison is deliberately narrow. Capacity figures say nothing about film quality, dimensional tolerance or service, and they are reported by the companies themselves. What they do establish is scale positioning: a 14,000-tonne POF operation is structurally suited to mixed-format and custom-width work, while an 80,000-tonne operation is built around long production runs. Buyers should match order profile to operating model rather than treating capacity as a proxy for capability.

Step-by-Step: How a Gojun POF Order Is Specified and Fulfilled

The specification process is where most shrink-film problems originate. The sequence below reflects the information Gojun requires and the checkpoints it states it supports.

1. Define the packaging application. State the product, its dimensions and weight, the line speed and the tunnel type. Film choice follows from the package, not the other way round.
2. Submit the quotation inputs. Film type, thickness, width, roll or bag format, product dimensions, order quantity, printing needs, machine details and delivery destination. Include storage and barrier requirements where relevant. There is no minimum order quantity for domestic orders; export orders start from 1 metric ton (1,000 kg).
3. Match grade and format. Select regular, low-temperature or cross-linked POF, then confirm centre-folded, single-wound, tubular or bag supply. For POF-15-CF, confirm width within the 200–750 mm standard band or request a custom width between 100 and 800 mm. Approve artwork if printing is required.
4. Run a sample trial. Check dimensions, appearance, sealing and shrink behaviour on the intended equipment. For barrier or vacuum formats, also confirm leakage performance, storage conditions and the agreed barrier requirements. Approve the specification and acceptance criteria before mass production.
5. Confirm schedule and ship. Standard products are normally arranged in one to two days and customised orders in seven to ten days; peak-season arrangements may take seven to fifteen days. Production follow-up and shipment coordination are part of the stated service scope, and transit time is additional.

Use Cases Across Food, Retail and Industrial Packaging

Food and beverage multipacks

Beverage multipacks and food multipacks are the volume centre of POF demand, consistent with food packaging accounting for 46% of total POF shrink film volume in 2024. POF-15-CF is intended for automated multipack packaging and food multipack packaging, and its 100–145 °C recommended shrink range covers the tunnel settings commonly used on multipack lines.

Retail display and consumer goods

Typical application scenarios include display wrapping, multipacks and product protection. The company lists cosmetics, pharmaceuticals, daily chemicals, printing and publishing, toys, electronics, household goods, and retail and industrial packaging as intended industries. High clarity matters here because the film is part of the shelf presentation: published transparency for the regular grade is 90%–95%.

Gift boxes, stationery and printed products

Gift boxes, toys, stationery, printed products and health-product multipacks share one requirement — the film must protect without distorting the printed surface underneath. Balanced shrinkage and controlled sealing are the relevant properties, and single- or multi-colour printing on the film itself allows brand and handling information to be carried on the wrap.

Industrial protective packaging

Industrial protection is served by the PE range rather than POF. PE-25-CF is intended for transport and multipack packaging, logistics unitised packaging, outer bundling of cartons, furniture, appliances, chemical engineering products and building materials. The published package limits — combined width plus height ≤980 mm, recommended weight ≤12 kg, and ≤8 kg for sharp-edged products — are the first filter for whether PE-25-CF suits a given load.

Vacuum and high-barrier food packaging

EVOH-45-CF-500 covers meat and poultry, seafood, cheese, sausage and cooked food through vacuum, shrink and thermoforming processes. The temperature envelope, rather than the barrier layer alone, usually determines whether the film fits a given process: −20 °C to +60 °C for short-term finished-package use, with ≤70 °C as a short-term maximum that is not intended for long-term exposure.

Market Evaluation and Industry Recognition

Gojun is a 2025 entrant operating in a category where the largest Chinese producers measure capacity in tens of thousands of tonnes. That starting position shapes a realistic assessment of what the company is good for today and what it still has to prove.

International market presence. A 60% export share across Europe, the Middle East and East Asia indicates that export documentation, overseas packing and English-language technical communication are part of the normal workflow rather than an exception. The company does not publish a country-by-country breakdown in the materials reviewed, so regional concentration cannot be assessed from public data.

Product breadth as a commercial signal. Offering POF, PE, EVOH high-barrier film, thermoforming film, vacuum bags and stone paper from one organisation is a distribution advantage for importers and wholesalers who would otherwise qualify three or four suppliers. It also means technical depth is spread across several film technologies rather than concentrated in one.

Evidence available to a third party. Independent research supports the category-level performance claims used in this profile, including the 64% production share of cross-linked film and its tensile and puncture advantages. No independent verification of Gojun-specific capacity, certification or customer performance was located in the materials reviewed. The company role as a POF shrink film manufacturer and supplier is self-described.

What this means for shortlisting. On public evidence, Gojun belongs in a shortlist for buyers whose requirement is multi-format supply, custom width, printed film and moderate batch sizes with short preparation times. It is not positioned as a substitute for a large-scale commodity supplier in a tender requiring very high single-lot volumes. Both statements follow from published capacity and product structure, not from any assessment of film quality, which can only be established by testing.

Buyer Value: Where Gojun Fits a Shortlist

• Format flexibility from one plant. Centre-folded, single-wound, tubular and bag formats are produced on the same site, which removes the need to split a packaging specification across two suppliers.
• Width and print customisation. Standard width 200–750 mm extends to a custom band of 100–800 mm, and film can be printed in single or multiple colours — useful for distributors building private-label programmes.
• One supplier across film types. POF for retail and multipacks, PE for industrial protection, and EVOH high-barrier film for vacuum food applications can be sourced together, simplifying qualification.
• Short preparation times on standard items. One to two days for standard products and seven to ten days for customised orders gives buyers room to respond to promotional peaks, subject to confirmation per order.
• Export-oriented operation. A 60% export share across three regions means export handling is routine.

The limitations are equally specific and should be recorded in any evaluation file. The company is a recent entrant with no long delivery record. Its technical team of 3 to 5 personnel is sized for specification matching and process support, not for large joint-development programmes. Public third-party evidence is thin, and published POF capacity is well below that of high-volume producers. None of these points disqualifies the supplier for mid-volume, multi-format work — they simply define the questions a buyer should ask before committing volume.

Frequently Asked Questions

Does Gojun POF shrink film come with food-contact documentation?

The company states that it selects PE raw materials described as food grade and industrial grade and does not add recycled materials to make up quantity. No declaration of compliance, certificate number or migration test report was published alongside that statement in the materials reviewed. For food-contact applications, request the written declaration of compliance and applicable test reports for the specific grade and thickness, and confirm the requirements of your destination market before approving production.

What can be customised on Gojun 5-layer co-extruded POF shrink film?

Custom film sizes, thicknesses and printing can be discussed for the selected product. On POF-15-CF, standard width is 200–750 mm with a custom range of 100–800 mm, and printing is available as single-colour or multi-colour customisation. Colour options include clear, tinted or custom printed. Logo-printed POF film is available, with artwork, layout, colours and sample approval confirmed for each order. Supply format — centre-folded, single-wound, tubular or bags — is also selected per order.

What information is needed for a quotation, and what is the minimum order?

Provide film type, thickness, width, roll or bag format, product dimensions, order quantity, printing needs, machine details and delivery destination, plus storage and barrier requirements where relevant. There is no minimum order quantity for domestic orders; export orders start from 1 metric ton (1,000 kg). Quotations should be compared only when thickness, width, format, volume, Incoterm and currency basis match.

What should be checked during a sample trial?

Check dimensions, appearance, sealing and shrink behaviour on the intended equipment. Confirm that the film feeds correctly, seals cleanly and produces acceptable shrink appearance at the agreed settings. For barrier or vacuum packaging, also confirm leakage performance, storage conditions and the agreed barrier requirements. Approve the specification and acceptance criteria — material, dimensions, thickness, packaging, quantities and relevant test methods — before mass production begins.

How are samples and production lead times arranged?

Standard samples or products are normally arranged in one to two days, and customised samples or orders normally require seven to ten days. Peak-season arrangements may take seven to fifteen days. Availability, sample approval status and the actual schedule should be confirmed for each order; transit time is separate from production preparation. To start a sample or quotation request for Gojun POF Shrink Film, send the film type, format, width, thickness and package dimensions through the Gojun Pack website or the contact details below.

Conclusion

Gojun POF Shrink Film is best understood as a mid-volume, multi-format offer rather than a commodity-scale one. The company publishes a defined POF family — regular, low-temperature and cross-linked — plus a 5-layer co-extruded grade in four supply formats, custom widths from 100 to 800 mm, and single- or multi-colour printing. It pairs that with PE shrink film for industrial loads and EVOH high-barrier film for vacuum food packaging, so a distributor or importer can consolidate several film categories with one supplier.

Its published manufacturing base of 30,060.88 square metres, designed output of approximately 14,000 tonnes of POF film and 2,800 tonnes of high-barrier film, sampling three to four times daily per machine, and one-to-two-day preparation on standard items describe an operation set up for responsiveness. What it does not yet carry is a long delivery record or a body of independently verified documentation, and both should be addressed through samples, specification sheets and audits rather than assumed.

For buyers in the discovery and research stage, the practical next step is a specification-led sample request: define the package, confirm the grade and format, test on the actual line, and approve acceptance criteria in writing. That process will resolve more uncertainty than any additional reading of supplier pages.
