Eco-Friendly POF Shrink Film: Compliance & Specification Guide for Buyers

Answer first: Eco-friendly POF shrink film should be evaluated as a documented material claim, not as a color or a marketing adjective. For Gojun POF Shrink Film, the verifiable starting points are a polyolefin (POF) 5-layer co-extruded structure, a clear appearance, a recommended shrink temperature of 100–145°C, and factory quality certificates with listed validity dates. The environmental claim itself needs market-specific evidence: food-contact documents where relevant, recyclability evidence, and current certificate status.

This guide is written for importers, distributors, brand owners and procurement teams who are moving from initial research to evaluation. It does not treat eco-friendly POF shrink film as a single product attribute. It separates what is documented in the supplied product and certificate records from what a buyer must request in writing before placing an order.

Problem Definition: The Eco-Friendly Label Is Not a Specification

The main procurement problem is not whether a supplier can print the words eco-friendly on a product page. The problem is whether the buyer can prove the claim for the destination market, the packaging application and the audit file. Three gaps appear repeatedly in early supplier evaluation.

• Environmental claim gap: A film may be described as environmentally friendly without naming a standard, a test method, a recyclability protocol or a certification number.
• Food-contact gap: A film may be intended for food and beverage packaging, but the buyer still needs a food-contact declaration, migration test or market-specific compliance document.
• Certificate gap: A supplier may hold a management-system certificate, but the certificate has a scope, a holder name and a validity period that must be checked against the order date.

These gaps matter because POF shrink film is used in visible retail packaging, food multipacks and consumer goods. A clear film can look identical in a photo while differing in polymer system, thickness, shrink behavior and documentation. The buyer's task is to convert the eco-friendly concept into an approved specification and an evidence file.

Industry Background: Why POF Claims Are Under More Scrutiny

POF shrink film sits inside the broader polyolefin shrink film market. A 2026 Grand View Research estimate places the global polyolefin shrink film market at USD 9.3 billion. Commercial estimates vary by scope, so the figure should be treated as directional rather than as a precise purchase-price index. The same source set notes that Asia Pacific accounted for a 40.0% revenue share in 2023.

Application data explains why buyers ask for more evidence. Precedence Research data cited in the verified data set indicates that food packaging contributes 46% of total POF shrink film volume, and that cross-linked POF films represent approximately 64% of total production volume. The same data set indicates that POF thickness grades between 15 µm and 25 µm cover more than 58% of total usage. These are market-level indicators, not a specification for every order.

Material identity is also part of the background. Shrink plastic film is commonly manufactured using polyethylene (PE), polyvinyl chloride (PVC) and polyolefin materials. POF is a polyolefin-based film, and polyolefin films are commonly made from PE and PP. That does not make every POF film identical. Buyers should confirm the exact polymer system and structure rather than relying on a category name.

The performance story is similarly nuanced. One commercial research source cited in the verified data set reports that cross-linked film provides 38% higher tensile strength and 29% better puncture resistance than standard POF. Those figures may be useful for early screening, but they do not replace a trial on the buyer's sealing and shrink equipment. A film that performs well in a data table can still fail if the machine settings, package shape or shrink tunnel profile are not matched.

The Gojun POF Shrink Film Solution: What Is Documented

Gojun POF Shrink Film is a polyolefin shrink-film product line supplied by Zhejiang Gojun New Material Technology Co., Ltd., which operates the Gojun Pack brand from Wenzhou, Zhejiang, China. The company focuses on flexible packaging materials and customized shrink-film solutions. Its core portfolio includes POF shrink film, EVOH high-barrier shrink film and PE shrink film.

The POF family includes Regular POF Shrink Film, Low-Temperature POF Shrink Film and Cross-Linked POF Shrink Film. The product-family reference is GJ-POF-SERIES. This code identifies the POF film family; the order-specific grade and dimensions are confirmed in the quotation. The POF-15-CF product is listed with a 5-layer co-extruded POF structure, standard width 200–750 mm, custom width 100–800 mm, recommended shrink temperature 100–145°C, and single-color or multi-color printing customization. The product is supplied in roll form and is available in centerfold, single-wound, tubular and bag formats.

For the Regular POF option in the GJ-POF-SERIES family, the published typical values are thickness 12–50 micrometres, width 100–1200 mm, shrinkage 65%–75% and transparency 90%–95%. These ranges do not define every grade in the family. The selected grade, film format, roll length, core size and tolerances must be confirmed before production. The shrink test temperature, time and relevant test methods should also be agreed in the approved specification.

The manufacturing base covers approximately 30,060.88 square metres. The team includes 40–60 employees and 3–5 technical personnel. Designed annual output is approximately 14,000 tonnes of POF film and 2,800 tonnes of high-barrier film. Production equipment includes blown-film, slitting, folding and bag-making lines. Each machine is sampled three to four times daily at different production stages for quality checks. Export markets include Europe, the Middle East and East Asia, and the export ratio is 60%.

Quality certification must be read carefully. The manufacturing factory for POF-15-CF POF Shrink Film holds ISO 9001:2015 Quality Management System Certificate 19823QI2345R0S. The certificate holder is Zhejiang Lianyi New Material Technology Co., Ltd., and the applicable standard is GB/T 19001-2016 / ISO 9001:2015. The certificate is issued by Beijing Xinjiyuan Certification Co., Ltd. and is listed as valid from 2023-09-22 to 2026-09-21. The certification scope covers production of plastic packaging film at the manufacturing factory for POF-15-CF POF Shrink Film.

The same factory record also lists ISO 45001:2018 Occupational Health and Safety Management System Certificate 19823SI1073R0S, issued by Beijing Xinjiyuan Certification Co., Ltd., with the same listed validity period of 2023-09-22 to 2026-09-21. The ISO 45001 certificate scope covers production of plastic packaging film, including POF Shrink Film (POF-15-CF). The certificate applies to the manufacturing factory and not directly to the POF Shrink Film product. As of October 2026, the listed validity period ended on 2026-09-21, so a buyer should request the current certificate or renewal evidence before supplier approval.

The food and beverage industry is a stated intended application for this POF shrink film. However, the supplied product and certificate records do not include a food-contact declaration or migration test report. A buyer should therefore request the market-specific food-contact document needed for the destination country before approving the film for direct food packaging.

Gojun describes its POF shrink film series as environmentally friendly and suitable for food or industrial packaging. The located evidence does not identify a specific environmental standard, recyclability protocol or certification number for that claim. The correct procurement response is not to ignore the claim, but to request the document that supports it for the target market. If the brief calls for recyclable POF shrink film, recyclability should be treated as a documentation requirement, not as an assumed property of every POF roll.

Step-by-Step: How to Verify an Eco-Friendly POF Shrink Film Order

Step 1: Define the application and destination market

Start with the packaged product, the distribution channel and the destination country. A food multipack, a gift box, a printed product and a household goods bundle do not raise the same compliance questions. The destination market determines which food-contact, labeling and waste-related documents the buyer should request. The product record lists food and beverage, cosmetics, pharmaceuticals, daily chemicals, printing and publishing, toys, electronics, household goods, retail and industrial packaging as application areas for the POF family.

Step 2: Confirm the polymer system and film grade in writing

Ask for the polymer system, the film structure and the grade name. For POF-15-CF, the documented structure is 5-layer co-extruded POF with polyolefin as the material. The POF family includes regular, low-temperature and cross-linked options. Do not accept a generic POF description if the order needs a specific grade. The quotation should state the grade, structure, thickness, width, format, roll length, core size and tolerances.

Step 3: Lock dimensions and format before sampling

POF-15-CF is listed with standard width 200–750 mm and custom width 100–800 mm. The Regular POF option in the family is listed with a typical width range of 100–1200 mm and a typical thickness range of 12–50 micrometres. These ranges are not a substitute for an order-specific specification. Confirm the exact gauge and tolerance, the roll or bag format, the core size and the packaging method. The product is supplied in roll form and is available in centerfold, single-wound, tubular and bag formats.

Step 4: Agree shrink and sealing conditions on the intended machine

The recommended shrink temperature is 100–145°C. That range is a starting point, not a guarantee that the film will perform on every machine. Agree the shrink test temperature, time and test method in the approved specification. Run a sample on the intended L-bar sealer, shrink tunnel or other compatible equipment. Check film feeding, sealing, shrink appearance and package integrity under the agreed settings. If the application requires printing, confirm artwork, layout, colors and sample approval for each order.

Step 5: Build the compliance file

Request the current ISO 9001:2015 and ISO 45001:2018 certificate records and check the holder name, scope and validity dates. The certificate holder for the POF-15-CF manufacturing factory is Zhejiang Lianyi New Material Technology Co., Ltd., not the brand owner. The ISO 9001 certificate number is 19823QI2345R0S. The ISO 45001 certificate number is 19823SI1073R0S. Both records list Beijing Xinjiyuan Certification Co., Ltd. as the issuing authority and a validity period of 2023-09-22 to 2026-09-21. Because the listed period ended on 2026-09-21, request the current certificate or renewal evidence for any order reviewed in October 2026 or later.

Step 6: Request food-contact and environmental evidence

The product is intended for the food and beverage industry, but the supplied records do not include a food-contact declaration or migration test. Request the document required by the destination market. For an environmental claim, ask for the specific standard, test method or certification that supports the words eco-friendly or recyclable. If no document is available, the claim should remain a supplier statement rather than an approved purchase specification.

Step 7: Approve a sample against written acceptance criteria

A sample trial should check dimensions, appearance, sealing and shrink behavior on the intended equipment. For barrier or vacuum packaging, the check would also include leakage performance, storage conditions and agreed barrier requirements, but those points apply to the relevant barrier products rather than to POF. Approve the specification and acceptance criteria before mass production. Standard samples are normally arranged in 1–2 days; customized samples normally require 7–10 days.

Step 8: Confirm commercial terms and quotation basis

The supplied data set does not include a verified price band or per-kilogram quotation for POF shrink film. Budget comparison should therefore use a written quotation that states film type, thickness, width, format, product dimensions, order quantity, printing needs, machine details and delivery destination. There is no minimum order quantity for domestic orders. Export orders start from 1 metric ton (1,000 kg). Standard products can normally be arranged in 1–2 days, customized orders normally require 7–10 days, and peak-season arrangements may take 7–15 days. Transit time is separate from production preparation time.

Use Cases and Application Fit

The POF-15-CF product record lists beverages, food multipacks, household and personal care products, gift boxes, toys, stationery, printed products and health-product multipack packaging as applicable industries. The wider POF family is listed for food and beverage, cosmetics, pharmaceuticals, daily chemicals, printing and publishing, toys, electronics, household goods, retail and industrial packaging.

Food and beverage multipacks

For food and beverage multipacks, the buyer should confirm the food-contact document required in the destination market before approving the film. The product is intended for the food and beverage industry, and POF-15-CF is listed for beverages and food multipacks. A clear wrap and a close-fitting package are useful only if the compliance file is complete. The buyer should also check that the shrink temperature and sealing settings are compatible with the product and the machine.

Retail display and consumer goods

For retail display, gift boxes, toys, stationery and printed products, appearance and print quality often matter as much as strength. POF-15-CF is listed with a clear appearance and single-color or multi-color printing customization. The buyer should define the accepted clarity level, print layout, color target and surface appearance before mass production. The Regular POF option in the family is listed with 90%–95% transparency, but that range does not define every grade.

High-speed and cross-linked evaluation

Cross-linked POF is one of the family options. The verified data set reports that cross-linked film provides 38% higher tensile strength and 29% better puncture resistance than standard POF, but those figures are market-level comparisons, not a machine guarantee. A buyer evaluating high-speed packaging POF should request a trial on the actual line and agree the acceptance criteria for film feeding, sealing, shrinkage and package integrity.

Custom printing and distributor programs

Logo-printed POF film is available, and POF-15-CF supports single-color or multi-color printing customization. Distributors and brand owners should confirm artwork, layout, colors and sample approval for each order. Custom sizes and logo printing are available subject to specification confirmation. The buyer should not assume that a printed roll and a clear roll share the same lead time or approval process.

Implementation record

A daily consumer goods manufacturer in the United States placed an initial order of 6 metric tons (6,000 kg) of POF-15-CF for heat-shrink packaging of gift boxes and multipacks. The customer required clear presentation, a neat close-fitting wrap, reliable seals and compatibility with its existing packaging equipment. The supplier matched film width and thickness to the package dimensions and equipment requirements, conducted sample testing, and confirmed bulk supply specifications after sample approval. The customer has used the film for 8 months, as of October 2026. The stated duration refers to project use, not the shelf life of the film or packaged goods.

Conclusion: Approve the Evidence, Then Approve the Film

Eco-friendly POF shrink film is a practical procurement category only when the environmental claim is tied to evidence. For Gojun POF Shrink Film, the technical starting point is clear: POF-15-CF is a 5-layer co-extruded polyolefin film with a recommended shrink temperature of 100–145°C, standard width 200–750 mm, custom width 100–800 mm and multiple roll or bag formats. The factory certificate record provides ISO 9001:2015 and ISO 45001:2018 references with listed validity from 2023-09-22 to 2026-09-21, which means a current certificate check is necessary for orders reviewed after that date.

The eco-friendly and food-contact aspects should be handled as document requests, not assumptions. Ask for the food-contact declaration required by the destination market. Ask for the specific standard, test method or certification behind any recyclability or environmental claim. Then validate the film on your own equipment with a written sample approval record. This sequence protects the buyer from approving a film that looks correct in a photo but lacks the documents needed for the audit file.
