About Packaging Shrink Film Rolls (POF, PVC, PE & PET)

Shrink film is a heat-activated plastic film that tightens around products to form a protective, tamper-evident skin when passed through a heat tunnel. Common grades are POF (high clarity, food-safe), PE (heavy-duty multipacks), PVC (low-cost, non-food) and PET (printed sleeve labels). It is used across food and beverage, cosmetics, electronics, pharmaceuticals and palletized industrial goods.

How to Choose

  • Film material - POF for food and retail clarity, PE for heavy or palletized loads, PVC for low-cost non-food items, PET for printed labels.
  • Shrink ratio and thickness - match shrink rate (typically 40-70%) and micron gauge to product shape and tunnel heat.
  • Roll format and width - confirm core size (1 inch or 3 inch), roll width and length fit your sealer and storage.
  • Clarity and finish - choose gloss, matte or high-transparency depending on shelf presentation.
  • Temperature and compliance - verify sealing temperature range and food-contact or RoHS status for your market.

FAQ

Q: What is the difference between POF and PE shrink film?
A: POF (polyolefin) is clear, soft and food-safe, ideal for retail and single items; PE (polyethylene) is thicker and tougher, used for heavy multipacks and pallet wrap where appearance matters less.

Q: Can shrink film be used with food products?
A: Yes. POF is widely used for food because it is odorless and non-toxic; PVC is generally avoided for direct food contact, while PE suits outer bundling rather than direct wrap.

Q: Which shrink film works best for printed labels?
A: PET shrink film offers high print quality and dimensional stability, making it the preferred choice for full-body shrink sleeve labels on bottles and cans.

Q: How do I choose the right film thickness?
A: Thickness depends on product weight and protection needs; lighter retail items use thin POF (around 12-25 microns), while heavy or sharp-edged goods need thicker PE gauges.
