Irradiation is used to standard Polyolefin Shrink Film to make the cross linked film more stronger, and have better seal strength. Cross linked shrink film is aseptic, FDA approved for food contact directly. It supply best appearance to show packaging products.
Cross linked shrink film leaves less residue on sealer to promote wire service life or longer sealing blade. It can be used for high output operations and high speed machines. It also used for heavy products commonly, but standard shrink film can not package correctly. The disadvantage of Cross Linked Film is that it need more higher sealing and shrink temperature. For sensitive products, higher temperature will deform and damage. And more higher temperature and seal also need energy costs.
