Shrink film has different types. These films have different features and characteristics. Shrink roll is divided into 3 main groups in terms of material and structure, which are:

3- POF shrink film

pof is the abbreviation of hygienic complete polyolefin and it is softer than PVC and is used for hygienic purposes that are related to food. POF or polyolefin shrink film is considered due to its flexible structure, tighter wrapping and less odor emission when heated.

Polyolefin shrink film roll production is more expensive than PVC samples. Therefore, many people prefer to use nylon shrink pvc. Polyolefin shrink film is one of the examples of sensitive type shrink films. This type of plastic has a lighter molecular weight. The molecules of this plastic are very sensitive to heat.
