PE Shrink Film

Polyethylene is a type of polyolefin, meaning it is a single monomer film that is formed with the addition of ethylene during polymerization. PE is used in several forms of flexible protective packaging including shrink film and stretch film, and performs very differently for each. 
There are multiple forms that PE can take, but the three most common would be Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), & High-Density Polyethylene (HDPE). Each of these are best used in different industrial applications, but for shrink packaging LDPE would be the most common form.
The benefits of using LDPE over the other forms of shrink packaging would be added strength and durability for heavier, larger items, like multipacks of beverages. These films are also printable and can have excellent graphics added while still maintaining the image and the strength required. Where POF and PVC are limited in gauge thickness to usually around 100 gauge, higher gauges of PE are possible up to 1200 gauge! These thicknesses are used in Marine industrial applications, like shrink-wrapping a boat for storage. The disadvantages of PE for shrink are that it doesn't have a high shrink rate, usually around 20%, and it has significantly lower clarity than the other films.

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 pocket
