Shrink Films By Aakriti Packaging

Shrink film market is comprised of two basic categories; the polyvinyl Chlorides (PVC) and the polyolefins. Shrink polyethylene is not typically included in the competitive polyolefin category; poly lacks the clarity, gloss and the tight second skin polyolefins provide. These attributes are critical for retail appeal.The polyolefin family consists of films made from polyethylene or polyethylene and polypropylene copolymer resins. All Cryovac Shrink film are polyolefins . Shrink film derive their properties from additives, which are primarily plasticizers. AS these films age, the plasticizers migrate and the film reverts to its brittle state, turning to a yellowish color. Also, PVC films tend to be temperature-sensitive, developing a tendency to shatter and split at cold temperatures (below freezing), and shrink-back and/or block when exposed to high temperatures over a period of time. The color may also change to yellow when exposed to heat (such as being stored in a non-air-conditioned warehouse over the summer).
