Polyolefin is a food grade film, and therefore can be used directly with food. PVC is not suitable for food packaging.
PVC is a rigid and brittle film while polyolefin is more pliable and does not tear as easily, making it a better option for bundling items.
Polyolefin does not yellow or become brittle with age like PVC.
When shrunk, polyolefin creates little odour or smoke, while PVC must be heated or shrunk in a well-ventilated room to prevent irritation from the smoke and odour. PVC may also leave a black residue on the film after sealing.
Polyolefin will give a clearer finish than PVC shrink film, and can be run on high speed on automatic machines.
A new technology now makes polyolefin shrink films such as the Cryovac CT-301 thinner and stronger, resulting in the use of less film.
