Multi-layer co-extrusion crosslinked PE shrinkable film with the comparison of POF shrink film

by:LINYANG     2020-03-16
Multi-layer co-extrusion crosslinked PE shrinkable film with the comparison of POF shrink film (1) crosslinked membrane shrinkage rate is higher than in POF film ( Two-way were over 70%, POF film of 60%) , the shrinkage temperature decrease. (2) than the POF film high heat sealing strength, heat sealing wide temperature range. As shown in figure 2 - 3. (3) crosslinked film packaging film surface friction does not exist POF film after the delaminating problem easily. (4) crosslinked film aging treatment and storage in the process of low shrinkage rate lower than POF film. (5) crosslinked film thickness uniformity is better than that of the crosslinked film. 6 and stiffness of the crosslinked membrane surface hardness increases, the mechanical scratch resistant surface. All landowners crosslinked membrane resistance to impact strength is higher than the crosslinked film. End up with special formula and process control parameters can be made high shrinkage rate, low shrinkage force of crosslinking shrink film, POF film can not be. Pet-name ruby due to shrinkage crosslinked membrane starting temperature is reduced, to some extent in the process of commodity packaging increase the contraction time, the contracting process, reduces the chance of packaging deformation and damage. Attending crosslinked membrane lower initial shrinkage temperature and heat sealing temperature range wide, for packaging and equipment requirements reduced, to some extent than using POF film can reduce the user's equipment investment.
