For food and beverage producers, the shrink film wrapping a multipack or retail tray is more than a protective layer — it is the last thing a shopper sees before picking a product off the shelf. Gojun Pack, the packaging materials brand of Zhejiang Gojun New Materials Technology Co., Ltd., has built a POF shrink film portfolio aimed squarely at that moment. The company pairs a broad product range with documented quality systems, making it a credible option for buyers who need transparent, durable secondary packaging that runs smoothly on automated lines.
The Gojun range covers the formats most food packagers actually order: center-folded film, single-wound film, tubular film and shrink bags. Behind those formats sits a family of grades — regular, low-temperature and cross-linked — each tuned to different transparency, sealing and mechanical strength requirements. For procurement teams weighing suppliers, the appeal is less about a single headline spec and more about how clearly the company separates marketing ranges from order-specific commitments.
What is Gojun Pack POF Shrink Film?
Gojun Pack is based in Cangnan County, Wenzhou, Zhejiang Province, and operates a manufacturing site of roughly 30,000 square meters with a workforce of 40 to 60 employees, including a small technical team. Its disclosed designed annual capacity includes 14,000 tonnes of POF shrink film and 2,800 tonnes of high-barrier film. The POF-15-CF product is a five-layer co-extruded film designed for varied packaging configurations, with standard widths from 200 to 750 mm and customized widths reaching 800 mm.
The GJ-POF-SERIES extends beyond the flagship grade to include regular, low-temperature and cross-linked options. That matters because a low-temperature grade and a cross-linked grade behave very differently on a shrink tunnel, and buyers who assume one catalogue figure applies across the family can end up with line problems. Gojun’s documentation is unusually direct about this: published typicals are for screening suppliers, while the approved specification sheet governs what will actually be accepted on delivery.
What stands out
Format and width flexibility
Few things slow a packaging line like film that does not match the equipment. Gojun offers center-folded, single-wound, tubular and bag formats, with standard widths from 200 to 750 mm and custom widths up to 800 mm. Single-colour and multi-colour printing options are also available, which helps brands that want the wrap to carry messaging rather than just protection.
Grade options for different line conditions
The series includes regular, low-temperature and cross-linked POF grades. Low-temperature film suits processes where heat exposure needs to be limited, while cross-linked film is typically chosen for strength and puncture resistance in tougher handling environments. The recommended shrink temperature for the POF-15-CF is 100 to 145°C, giving operators a workable window for tuning tunnel settings.
Clear documentation discipline
Gojun publishes typical values for its Regular POF option — 12 to 50 micrometres in thickness, 100 to 1200 mm in width, 65% to 75% shrinkage and 90% to 95% transparency — while stating that final values follow the approved specification sheet. That distinction is a practical one: it tells buyers exactly which document to use when qualifying a supplier and which to use when accepting a delivery.
Disclosed quality systems
The company discloses ISO 9001:2015 and ISO 45001:2018 certificates issued by Beijing Xinjiyuan Certification Co., Ltd., with stated validity ending September 21, 2026. Buyers should request updated certificates before relying on their current status, but the willingness to publish certificate numbers is a useful signal of process maturity.
Export experience
Europe, the Middle East and East Asia are identified as principal export markets, accounting for roughly 60% of output. A disclosed customer project involved a US daily consumer goods manufacturer placing an initial 6-metric-ton order of POF-15-CF and using the material for eight months as of October 2026 — a concrete example of international supply experience rather than a generic claim.
Who it’s for
Gojun Pack’s range is best suited to food and beverage producers, co-packers and consumer goods manufacturers that need secondary packaging film in volume and care about matching film grade to line conditions. It is also a reasonable fit for brands that want printed shrink film for retail presentation without sourcing from multiple suppliers. The minimum export order of 1 metric ton keeps the door open to mid-sized buyers, not just large accounts.
Buyers who need extremely fast turnaround on highly customized specifications may find the stated 7 to 10 day lead time for customized orders worth planning around. Standard products are generally quoted within one to two days, so straightforward repeat orders move quickly. Companies that treat a published typical as a guarantee, rather than engaging with the approved specification process, are likely to be frustrated — but that is a qualification discipline issue rather than a product flaw.
What makes it worth considering
The strongest argument for Gojun is the combination of breadth and documentation. A buyer can source regular, low-temperature and cross-linked grades from one supplier, in multiple formats and widths, with printing available and a clear statement of which figures are typicals and which are contractual. That reduces the number of suppliers a packaging team has to manage and simplifies the qualification process.
Environmental considerations are also part of the portfolio, with recyclable POF materials promoted alongside conventional grades. As with any recyclability claim, the practical outcome depends on material composition, collection infrastructure and local recycling requirements, so buyers should evaluate claims against product documentation and regional standards. Handled that way, the range offers a sensible path for brands under pressure to improve packaging sustainability without abandoning POF performance.
Verdict
Gojun Pack presents a well-organized, food-oriented POF shrink film range with the format flexibility and grade variety that real packaging lines demand. The company’s emphasis on approved specifications over published typicals is a sign of maturity that procurement teams will appreciate. Buyers should verify current certificate validity and confirm final specs directly, but as a supplier to shortlist for secondary food packaging, Gojun earns a confident recommendation.
