The simple answer is yes. It is advisable to do this on volume lines, though.

What temperature does POF shrink at?

Generally POF shrinks at around 150 degrees C. It is important to understand that the heat of the tunnel, the length of the tunnel, the speed through the tunnel and the type of pack being covered all need to be controlled to get the perfect shrink.

Do I need special ventilation for POF?

Not because of the film. The ventilation needs to be appropriate for the heat tunnel though.

How thick must the skin pack film be?

Generally speaking, the heavier the item being packed, the thicker the film.

AI-Powered supplier vetting

SummaryThe supplier manufactures packaging films, including POF shrink film, stretch film, PE/PVC shrink film, and related packaging materials. It reports multiple co-extrusion production lines, production capacity exceeding 6,000 tons annually at the facility, and additional annual productivity figures for specific products. The supplier has exported goods for nine years, with exports representing 51%–70% of total sales, and can quote FOB, CIF, CFR, and EXW terms. Its quality controls include quality assurance, raw-material traceability, random finished-product inspection, and one quality inspector. However, it does not provide 3D software design, ODM, SDK, overseas warehouse, overseas agent or branch, showroom, or offline trade-show services. Written procedures are absent for supplier-service assessment, corrective and preventive actions, and customer complaints. Certification status, after-sales capability, and customer cases are not sufficiently evidenced.

Supplier typeThe supplier is a packaging-film manufacturer rather than a professional technical supplier. Its stated products include shrink film, stretch film, shrink bags, and other packaging materials, supported by co-extrusion production lines and reported manufacturing capacity.

After-Sales capabilityThe supplier lacks overseas warehouses, showrooms, agents, and branches, and reports no written procedures or records for handling customer complaints. These explicit gaps indicate limited documented after-sales and overseas service infrastructure.

R&D capabilityThe supplier reports no new products in the past year, no 3D software design services, no ODM services, and no available SDK. These explicit limitations demonstrate weak documented innovation and product-development capability.

Production capacityThe facility has four five-layer and three three-layer co-extrusion lines, reports annual facility capability above 6,000 tons, and lists productivity for POF shrink film, stretch film, and PE/PVC shrink film. It also reports peak- and off-season lead times within 15 workdays, supporting a positive assessment of production capability.

Customization capabilityThe supplier explicitly offers customization from samples, and this capability is recorded both under R&D-related design services and general design services. However, no broader engineering or digital-design capability is evidenced.

Product Q&A

Q:What does POF mean?

POF is an abbreviation for polyolefin and generally refers to heat shrinkable shrink film.

Q:What equipment is needed to shrink POF?

Various machines are used, from simple heat guns to conveyor driven heat shrink tunnels. The product, volumes and purpose dictate the appropriate solution.

Q:How is the shrink film sealed?

There are many ways of sealing the pack from a simple bar sealer, an L sealer and on to the automated machines like continuous side seal and flow wrappers.

Q:What is a centrefold roll?

Shrink film is often folded and then rolled so that when the roll is unwound, it has an open and a closed side. This is done to improve the packing efficiency when using an L sealer.

Q:What is single wind or lay flat?

This is simply a roll of film wound in a single layer. This is used for flow wrapping machines or many other automated machines.
