Perforated POF shrink film is a polyolefin (POF) shrink film supplied with a perforation pattern added to the film format. Perforations are commonly used to release trapped air during shrinking and to provide controlled ventilation where a pack needs airflow. The purchasing risk is that the perforation pattern, gauge, roll format and compliance documents are treated as one catalogue entry. In the POF Shrink Film data published for model POF-15-CF, the listed formats are centerfold, single-wound, tubular and bags; standard width is 200–750 mm; custom width is 100–800 mm; and the recommended shrink temperature is 100–145 °C. Perforation geometry is not fixed in that published data, so it must be written into the approved specification before production.

What "Perforated" Adds to a POF Purchase Specification

Perforation is a format decision layered on top of a material and gauge decision. The material decision is already documented: Gojun POF Shrink Film is made of polyolefin (POF) with a 5-layer co-extruded structure, and the film appearance is clear. The format decision covers how the film leaves the factory — centerfold, single-wound, tubular or bag — and perforation sits inside that second decision.

Four specification lines therefore have to be agreed separately from the film grade:

• Hole geometry. Diameter, spacing and pattern (single row, staggered, zoned). These values are application-specific and are not published as fixed figures in the POF product data reviewed for this guide.
• Perforated zone. Full-width perforation versus an edge or centre band, and the distance kept clear of seal areas.
• Roll configuration. Width, roll length and core size, confirmed against the packaging machine rather than against the product alone.
• Acceptance criteria. What the trial looks like when it passes — shrink appearance, seal integrity and the position of perforations relative to the seal.

This is where most perforated-film orders lose time: the buyer specifies "perforated POF" and the supplier quotes a standard film, because the four lines above were never written down.

Problem Definition: Four Constraints That Decide a Perforated POF Order

1. Perforation is treated as a stock item, not a specification line

Published POF data defines grade, thickness, width, format, printing and shrink temperature. It does not define hole diameter or count. A buyer who orders from the catalogue description rather than an approved drawing has no agreed basis for rejecting a roll, and no agreed basis for a repeat order either.

2. Width and gauge are chosen from the product, not the machine

Standard width for POF-15-CF is 200–750 mm and custom width is 100–800 mm, with a recommended shrink temperature of 100–145 °C. Those are film-side numbers. The operational constraint is machine-side: a film that shrinks correctly in a tunnel but cannot feed, seal or release consistently on the buyer's line is still the wrong film. Sample verification on the intended equipment closes that gap; a specification sheet alone does not.

3. Certification is assumed to cover the product and to be current

The POF-15-CF manufacturing factory holds ISO 9001:2015 Quality Management System Certificate 19823QI2345R0S and ISO 45001:2018 certificate 19823SI1073R0S. Both are factory-level certificates: the scope is production of plastic packaging film, and the holder is Zhejiang Lianyi New Material Technology Co., Ltd. The recorded validity runs from 2023-09-22 to 2026-09-21. A buyer auditing in late 2026 should therefore request the current certificate status rather than relying on the historical record, and should not read a management-system certificate as a food-contact approval.

4. Order quantity and lead time are planned after the specification is agreed

Export orders start from 1 metric ton (1,000 kg) and domestic orders carry no minimum order quantity. Standard products are normally arranged in 1–2 days and customized orders in 7–10 days, with 7–15 days in peak season. Reversing the sequence — booking production before the perforation drawing is signed — is the usual cause of a missed launch date.

Industry Background: Why POF and Why Format Detail Matters

POF sits inside a large, well-documented film category. Grand View Research reported the global polyolefin shrink film market at USD 9.3 billion in 2026; estimates from different research providers vary because the scope of included film types differs, so the figure is best used as an order of magnitude rather than a planning constant. Precedence Research reported that cross-linked POF accounted for approximately 64% of total production volume in 2024, and that film gauges between 15 µm and 25 µm covered more than 58% of total usage — a useful signal that most POF demand is satisfied by thin, high-performance gauges rather than by heavy film.

Application data points the same way. Precedence Research estimated that food packaging contributes 46% of total POF shrink film volume, and Asia Pacific held a 40.0% revenue share in 2023 according to Grand View Research. The practical reading for a buyer is that POF specifications are usually negotiated against food and beverage multipack requirements, and that thin-gauge film dominates — which is exactly where small specification errors (gauge, perforation zone, seal clearance) become visible on the line.

The supplier behind this guide is Zhejiang Gojun New Material Technology Co., Ltd., which operates the Gojun Pack brand from Wenzhou, Zhejiang, China and was established in 2025. The manufacturing base covers approximately 30,060.88 m², with 40–60 employees and 3–5 technical personnel. Designed annual output is approximately 14,000 tonnes of POF shrink film and 2,800 tonnes of high-barrier film; 60% of output is exported, mainly to Europe, the Middle East and East Asia. Production equipment includes blown-film, slitting, folding and bag-making lines — the lines that determine which formats, including perforated formats, can actually be delivered.

Detailed Solution: The Documented POF Basis for a Perforated Order

The solution is not a new film. It is a correctly written order on a documented film. Gojun publishes the POF family as GJ-POF-SERIES, covering Regular POF Shrink Film, Low-Temperature POF Shrink Film and Cross-Linked POF Shrink Film, with model POF-15-CF supplied as centerfold, single-wound, tubular or bags.

Material and structure

Polyolefin (POF) is the primary material, and the structure is 5-layer co-extruded. The film appearance is clear — a relevant detail for retail multipacks, gift boxes and printed products where the pack is meant to be read through the film.

Dimensions and processing window

Standard width is 200–750 mm and custom width is 100–800 mm. The recommended shrink temperature is 100–145 °C. For the broader GJ-POF-SERIES family, 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 family and do not define every grade in it. Where a perforated format is required, the pattern is an additional line on the same approved specification, and its feasibility is confirmed before production together with grade, film format, roll length, core size and tolerances.

Printing and customization

Single-colour or multi-colour printing is available as a customization on the POF-15-CF specification. Custom film sizes, thicknesses and printing can be discussed for the selected product, with the caveat that artwork, layout, colours and sample approval are confirmed for each order.

Documented applications

POF-15-CF is documented for beverages, food multipacks, household and personal care products, gift boxes, toys, stationery, printed products and health-product multipacks. The product is recorded as intended for the food and beverage industry. Perforation does not change that list; it changes how the film behaves on the machine and how the finished pack ventilates.

What the published data does not answer

Hole diameter, hole count, spacing, open area and the exact perforated zone are not published as fixed values. That is not a gap to be filled with an assumed number — it is a specification line to be agreed. A buyer who needs a defined pattern should supply a drawing or a physical sample and have the pattern restated in the approved specification, so that the first bulk delivery and the tenth bulk delivery are measured against the same document.

Step-by-Step Breakdown: Specifying, Sampling and Releasing a Perforated POF Order

Use Cases: Where Perforated POF Fits and Where It Does Not

Food and beverage multipacks

Food packaging accounts for an estimated 46% of POF volume. Beverage multipacks and food multipacks are the classic POF application: a clear, close-fitting wrap that holds units together and stays readable on shelf. Perforation is used where air must escape from the pack during shrinking or where the product needs ventilation after wrapping.

Gift boxes, daily goods and health-product multipacks

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 equipment. The film has been in use for 8 months as of October 2026. The supply plan was straightforward and repeatable: match film width and thickness to package dimensions and equipment, test samples, then confirm bulk specifications after sample approval. Perforation requests are handled the same way — pattern first, then bulk.

Household, personal care, stationery, printed products and toys

These applications rely on the same documented properties: clear appearance, balanced shrink and multi-format supply. For printed products and stationery, perforation can also reduce the risk of a tight wrap marking a folded edge, but this must be proven on the actual product rather than assumed from a grade name.

Where perforated POF is the wrong choice

Barrier and vacuum applications are a different product family. EVOH high-barrier film (EVOH-45-CF-500) is built as a PA/EVOH/PE multilayer for meat, poultry, seafood, cheese, sausage and cooked-food vacuum packaging, with a short-term finished-package use range of −20 °C to +60 °C and a maximum short-term temperature of ≤70 °C. A deliberately perforated web works against that barrier function, so ventilation requirements and barrier requirements should be settled before a film family is chosen. Heavy or sharp-edged industrial loads are also a different decision: PE shrink film (PE-25-CF) is documented with package limits of ≤980 mm width plus height, ≤12 kg package weight and ≤8 kg for sharp-edged products.

Comparison Tables

Budget Planning Without a Published Price List

No POF price band is published in the product data reviewed for this guide, and quoting a figure without a specification basis would be misleading. What can be stated is the commercial framework a buyer should plan around: export orders start from 1 metric ton (1,000 kg), domestic orders carry no minimum, and the quotation is built from film type, thickness, width, roll or bag format, product dimensions, order quantity, printing requirements, machine details and delivery destination.

In practice, four variables move a perforated POF quotation most: perforation pattern complexity (an added converting step rather than a film property), gauge and width, printing (single versus multi-colour), and order quantity against the 1-tonne export threshold. Asking for two or three configurations in one request — for example a plain roll and the perforated version at the same width — makes the cost of the perforation step visible instead of buried.

Conclusion

Perforated POF shrink film is a documented film plus a written format decision. The film side is settled: polyolefin, 5-layer co-extruded, clear, standard width 200–750 mm with custom width 100–800 mm, recommended shrink temperature 100–145 °C, printing available, and a family that also includes low-temperature and cross-linked grades. The format side is where orders succeed or fail: hole geometry, perforated zone, seal clearance and acceptance criteria belong in the approved specification, not in a purchase order description.

The compliance picture is equally specific. ISO 9001:2015 certificate 19823QI2345R0S and ISO 45001:2018 certificate 19823SI1073R0S cover production of plastic packaging film at the manufacturing factory that produces POF-15-CF, with recorded validity from 2023-09-22 to 2026-09-21 — which is why current status and a destination-market food-contact declaration should be requested as part of supplier qualification rather than assumed.

Sequence the work in this order: define the pack, fix grade and gauge, fix width and format, write the perforation specification, trial a sample on the real machine, confirm documents, then release production against the 1-tonne export threshold. That order keeps the perforation pattern, the film and the paperwork aligned.
