Polyolefin Shrink Film, commonly referred to in the packaging industry as shrink films, is manufactured and classified as a plastic product. During manufacturing, the plastic-based material is manipulated to produce a continuous thin film that is then tightly wound onto thick, layered cardboard rolls commonly referred to as cores.
Shrink-wrap rolls are produced in various lengths and widths; roll lengths range from 1,100 to 17,500 linear feet and roll widths range from 3 to 70 inches. Available roll lengths and widths vary depending upon the shrink-wrap wind and type.
There are a variety of shrink films types. Each shrink films type is designed with special characteristics to meet specific packaging needs. For example, Sealed Air's Cryovac line consists of 9 different shrink films - each provide product-tailored performance.
