Stretch films are made from linear low-density polyethylene resins. Since its early introduction in the early 70’s, stretch film has become the most important method of unitizing product loads for transport. There are a number of key features for this including:
Stretch Film Manufacturing Methods
There are two basic manufacturing methods to create stretch film. Without needing to get into technical detail they are:
Blown film is created by forcing molten resin through a circular die, creating a tube, which is “blown some 30 feet high”. The bubble is then flattened and cut into strips that when rolled will produce rolls of flat film. Blown film is generally “labeled” as a tough, hazy, and noisy stretch film best suited for “industrial” type applications.
