POF, PE and EVOH shrink films are not three grades of one product. They are three answers to three different packaging questions. A buyer who compares them on a single axis — price per kilogram, shrinkage percentage or film thickness — usually ends up with either a wrap that fails in the shrink tunnel or a specification nobody needed to pay for. POF is the presentation film, PE is the protective film, and EVOH multilayer film is the barrier film for vacuum food packaging. That split is the starting point for evaluation, not a ranking.

Why Most POF vs PE vs EVOH Comparisons Mislead Buyers

The comparison problem is not a lack of data. It is that the available numbers are produced under different conditions and then placed in the same table without correction. Three specific mistakes account for most wrong film decisions.

Mistake 1: Comparing shrinkage figures measured under different conditions

Published typical values for the regular POF option give 65%–75% shrinkage. The PE-25-CF film is specified at 45%–53% machine-direction and 48%–56% transverse-direction shrinkage, measured by a free-shrink test at 125°C for 5 minutes. EVOH-45-CF-500 is documented by a free-shrink test at 130°C for 5 minutes rather than a percentage. These are not the same measurement, so a direct numerical comparison is invalid. The shrinkage test temperature, time and method must be agreed in the approved specification before any two films are set side by side.

Mistake 2: Reading clarity as protection

POF delivers 90%–95% transparency in the published typical data for the regular option, which is why it dominates display wrapping. Transparency says nothing about oxygen or moisture transmission. In the reviewed specifications, only EVOH-45-CF-500 names a high-barrier structure: a PA/EVOH/PE multilayer. No oxygen-barrier value is published for POF-15-CF or PE-25-CF, so barrier parity must not be assumed in either direction.

Mistake 3: Choosing the material before checking the machine

Recommended shrink temperatures differ by family: 100–145°C for POF-15-CF, a 125°C free-shrink test condition for PE-25-CF, and a 125–145°C tunnel range with 130–140°C recommended for EVOH-45-CF-500. A tunnel that cannot hold the required band will produce a loose or distorted pack regardless of how good the film is.

Industry Background: Why Three Film Families Coexist

Shrink plastic film is commonly manufactured from polyethylene, polyvinyl chloride and polyolefin materials, and each family settled into a different role because packaging lines, retail formats and food-distribution requirements pulled them in different directions. Polyolefin is a polymer family built on polyethylene and polypropylene, which is why POF behaves as a stiff, glossy, high-clarity film compared with a plain polyethylene film of similar gauge.

Third-party market research covering this category indicates that food packaging accounts for 46% of total POF shrink film volume, that cross-linked POF grades represent roughly 64% of production volume, and that 15–25 µm thickness grades cover more than 58% of total usage. The practical reading for a buyer is that the mainstream specification zone is thin-gauge, food-adjacent and increasingly cross-linked — but mainstream is not the same as correct for a specific pack.

What Each Film Family Is Actually Built to Do

POF: the presentation and multipack film

Gojun POF Shrink Film is a polyolefin shrink film family supplied by Gojun Pack, the brand operated by Zhejiang Gojun New Material Technology Co., Ltd. from Wenzhou, Zhejiang, China. The family covers regular, low-temperature and cross-linked grades. The POF-15-CF grade is a 5-layer co-extruded structure available in center-folded, single-wound, tubular and bag formats, with standard width 200–750 mm, custom width 100–800 mm, a recommended shrink temperature of 100–145°C, and single-colour or multi-colour printing.

Published typical values for the regular POF option are 12–50 µm thickness, 100–1200 mm width, 65%–75% shrinkage and 90%–95% transparency. Those ranges describe the option, not every grade inside the family, so the order-specific grade and dimensions have to be confirmed in the quotation.

PE: the protective and load-bundling film

PE-25-CF is a 25 µm polyethylene film supplied at 550 mm width. It is listed for furniture, appliance, chemical-engineering and building-material shrink applications, alongside a recyclable PE shrink film type. Its specification is unusually concrete on package limits: maximum package width plus height of 980 mm with 920 mm recommended, recommended maximum width 460 mm, recommended maximum height 200 mm, and recommended package weight of 12 kg, reduced to 8 kg for sharp-edged products.

Those limits matter more than the shrinkage figure in most industrial purchases. A buyer wrapping furniture or appliance loads can check the pack against hard numbers instead of relying on a trial-and-error loop.

EVOH: the barrier film for vacuum food packaging

EVOH-45-CF-500 is a PA/EVOH/PE multilayer high-barrier film at 45 ± 4 µm and 500 mm width. It is listed for meat and poultry, seafood, cheese, sausage, cooked food and vacuum food packaging, and is offered as cooking vacuum bag, low-temperature vacuum bag, high-barrier shrink bag and thermoforming film formats. The free-shrink test condition is 130°C for 5 minutes; the shrink-tunnel range is 125–145°C with 130–140°C recommended. Finished packs are rated for short-term use from −20°C to +60°C, with a maximum short-term temperature of 70°C and no long-term exposure at that level. Recommended storage is 30°C or below.

The Five Decision Variables That Separate the Three Films

1. What the packaged product must be protected from

Abrasion and load stability point to PE. Oxygen and moisture ingress in a vacuum pack point to EVOH. Retail presentation and tamper evidence point to POF. If two requirements collide — for example a retail pack that also needs a barrier — the correct answer is usually a different pack format, not a compromise film.

2. Barrier requirement

Only EVOH-45-CF-500 carries a named high-barrier multilayer structure in the reviewed data. If the product needs a vacuum format with a defined barrier level, the film grade, thickness, barrier level, sealability and processing temperature must be confirmed against the packaging equipment and the applicable food-contact requirements — not inferred from the material name.

3. Package size, shape and weight against film limits

PE-25-CF publishes explicit package limits. POF-15-CF and EVOH-45-CF-500 do not publish equivalent weight or size caps in the reviewed specifications, which means those limits must be established per application during sampling.

4. Equipment and shrink-tunnel conditions

Sealing method, tunnel temperature band, roll format, roll length, core size and tolerances all belong in the quotation conversation. POF-15-CF is specified for a 100–145°C recommended shrink temperature, which leaves room for lower-temperature lines; EVOH-45-CF-500 expects a 130–140°C recommended tunnel band.

5. Presentation, format and printing

POF-15-CF supports single-colour or multi-colour printing and four formats — center-folded, single-wound, tubular and bags — which is what makes it usable across a mixed production floor. PE-25-CF and EVOH-45-CF-500 specifications in this data set do not state printing options.

Specification Reference: Verified Figures Side by Side

Blank or “not published” cells are genuine gaps in the reviewed specifications. They must be closed by the supplier in writing before a purchase order is issued.

Step-by-Step: How to Validate a Film Choice Before You Order

1. Write the protection statement first. One sentence describing what the pack must survive — retail handling, a cold chain, a vacuum cycle, a pallet stack. This decides the family before any number is discussed.
2. Audit the line before the film. Record the sealing equipment type, the tunnel's achievable temperature band and its stability, and the roll format the machine accepts. Compare that band against the film's stated range: 100–145°C for POF-15-CF, a 125°C free-shrink condition for PE-25-CF, 130–140°C recommended for EVOH-45-CF-500.
3. Measure the pack, not the product. Film is sized against the finished bundle. For PE-25-CF, check the width-plus-height figure against 980 mm, the recommended 460 mm width and 200 mm height, and the 12 kg weight ceiling, dropping to 8 kg where edges are sharp.
4. Match gauge to abuse level. Thickness choices move within 12–50 µm for the POF family, against a fixed 25 µm for PE-25-CF and 45 ± 4 µm for EVOH-45-CF-500. Thin gauge saves material; it does not save a pack that is being punctured in transit.
5. Settle the barrier question in writing. If the pack needs a barrier, the EVOH grade, thickness, barrier level and sealability have to be confirmed against the equipment and the applicable food-contact requirements. Do not accept a material name as evidence.
6. Agree the test method and the acceptance criteria. Fix the shrink test temperature and time, the appearance standard, seal strength and, for vacuum formats, leakage performance and storage conditions. Confirm the storage envelope as well — EVOH-45-CF-500 is recommended for storage at 30°C or below.
7. Approve a sample, then lock the bulk specification. Check dimensions, appearance, sealing and shrink behaviour on your own equipment. Before mass production, confirm the selected grade, film format, roll length, core size, tolerances and printing artwork against the approved specification.

Use Cases: Where Each Film Earns Its Place

POF in display and multipack work

POF-15-CF is listed for beverages, food multipacks, household and personal care products, gift boxes, toys, stationery, printed products and health-product multipacks. A representative implementation: a daily consumer goods manufacturer in the United States placed an initial order of 6 metric tons of POF-15-CF for heat-shrink packaging of gift boxes and multipacks, requiring clear presentation, a neat close-fitting wrap, reliable seals and compatibility with its existing packaging equipment. The film has been in use for 8 months as of October 2026. That duration refers to project use, not the shelf life of the film or the packaged goods. The supply plan was to match film width and thickness to the package dimensions and equipment, run sample testing, and confirm bulk specifications after sample approval.

PE in industrial and transit protection

PE-25-CF is listed for beverage and alcoholic-drink multipacks, outer bundling of cartons, household and personal care products, small hardware, building materials and logistics unitized packaging. Its value is in the published load envelope: a buyer can reject a film size before the first pallet is wrapped, simply by measuring the pack.

EVOH in vacuum food packaging

EVOH-45-CF-500 is listed for meat and poultry, seafood, cheese, sausage, cooked food and vacuum food packaging. The selection logic here is driven by the barrier and the cold chain: a finished pack rated for short-term use from −20°C to +60°C, with a 70°C maximum short-term ceiling, tells the buyer what the distribution window can look like without additional assumptions.

Comparison Table: Matching the Film to the Packaging Job

Customization and Supply Capability: What Gojun Pack Can Confirm

Zhejiang Gojun New Material Technology Co., Ltd. operates the Gojun Pack brand from Wenzhou, Zhejiang, China, on a manufacturing base of approximately 30,060.88 m² with 40–60 employees and 3–5 technical personnel. Production equipment includes blown-film, slitting, folding and bag-making lines, with a designed annual output of about 14,000 tonnes of POF shrink film and 2,800 tonnes of high-barrier film. Around 60% of output is exported, to Europe, the Middle East and East Asia.

On customization, the useful answer for a buyer comparing three families is granular rather than general: POF options include regular, low-temperature and cross-linked films, and film format, thickness, width and logo printing can be matched to the application. Final specifications and feasibility are confirmed before production. For POF-15-CF specifically, standard width is 200–750 mm with 100–800 mm available as a custom width.

Capacity, order quantities and lead times

Indicative monthly capacity, calculated from annual design capacity divided by twelve rather than from actual monthly output, is approximately 1,166.67 tonnes for POF, 233.33 tonnes for EVOH and 200 tonnes for PE shrink film. Domestic orders carry no minimum order quantity; export orders start at 1 metric ton (1,000 kg). Standard products are normally arranged in 1–2 days and customized orders in 7–10 days, with peak-season arrangements taking 7–15 days. Standard samples take 1–2 days and customized samples 7–10 days; transit time is additional in every case.

Frequently Asked Questions

Conclusion

The choice between POF, PE and EVOH shrink film is settled by the package, not by the film. POF earns its place where 90%–95% typical transparency, 65%–75% typical shrinkage, a 100–145°C recommended shrink range and multi-colour printing matter. PE earns its place where a 25 µm film with explicit package limits — 980 mm width plus height, 12 kg, 8 kg for sharp edges — protects a heavier or harder-edged load. EVOH earns its place where a PA/EVOH/PE multilayer, a 130–140°C recommended tunnel band and a −20°C to +60°C short-term pack range are what the food product actually requires.

None of those three statements outranks the others. The buyer's job is to write the protection statement, audit the line, size the pack, settle the barrier question in writing, and approve a sample before the bulk specification is locked.
