Usage
PW 70 is designed to produce stretch film from LLDPE, LDPE or other polyolefins for the applications of palletwrap, silagewrap and foodwrap. It can be used in both blown or cast film process. Polymers used with PW 70 must not contain any slip or antiblock additives or have a density higher than 0.923 as this will prevent the migration of the cling additive.
Migration time for good cling properties is 24-72 hours.
