Cross Link POF

In the production process, the radiation cross-linking technology was adopted to change the polymer chain of the resin from linear structure to mesh body structure, thus significantly improving the properties of the shrinkage film, which is mainly reflected in the following aspects. The first is to greatly improve the film shrinkage rate (up to 80%), so that the film shrinkage more paste body, the packaging effect is better. Then it improves the strength and toughness of the film, making the packaging stronger. Secondly, the thermal sealing performance of the film is also improved, so that the sealing is more firm, and the "drawing" phenomenon at the sealing place is completely avoided. In addition to these three items, the heat resistance and cold resistance of the film are also improved to a certain extent, making its adaptation range become more extensive.
