Polyolefin shrink is an extremely durable and versatile ‘premium’ shrink film. It has taken then place of PVC mentioned above in many applications, and is also an FDA-approved food-safe material. Polyolefin materials are available with different characteristics, including cross-linked film that provides high-tensile strength and incredible clarity for high-speed packaging applications. Cross-linked film also prevents buildup on sealing components of machinery.

With added strength, the ability to create longer rolls of film with thinner gauges available that allow for less roll change-over and increased efficiency and productivity. Polyolefin shrink film has excellent puncture-resistance and seal-strength, allowing for irregular-shaped items to have excellent protection throughout its supply chain life-cycle. POF is available in thicknesses as low as 35-gauge (.35 mil), and is more commonly available in 45,60, 75 and 100 (1 mil) gauges.

The versatility and fairly low-cost that POF offers for multiple machines and packaging forms makes it a go-to form of protective packaging manufacturers of any size. In some instances POF will need perforations added to the film; tiny holes added to the film before application which allow air to escape during the shrinking process for a smooth package. Pre-perforated shrink film is available by many suppliers for this reason.

Fast Facts About POF Shrink Film

    • Premium quality shrink film, AKA high-clarity, decorative shrink wrap.
  • Made of 100% recyclable materials
  • Excellent clarity and glossy shelf appearance; great for consumer products where appearance is critical (toys, games, candies, books, foods, most retail items)
  • Ability to shrink quickly and completely (shrinks when heated resulting in a finished good as soon as it comes out of the shrink tunnel)
  • Durable, versatile, low cost
  • Excellent for bundling multiple items together, like tissue boxes for example.
  • Cross-linked POF is great for high-speed applications, providing added strength without compromising clarity and prevents build-up on sealing components
  • Polyolefin is more expensive, but more durable- not as effected by temperature changes
  • FDA approved for food contact
  • Excellent tensile-strength and propagation-to-tear
  • Pre-perforated POF  is available and allows for even shrink surface, no air pockets
