USAGE
PW60 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 PW60 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.
RECOMMENDED ADDITION RATES
For monolayer blown films 3 % PW60 by weight should be added to LLDPE ( or resin mix). For monolayer Cast films 1% and 2% PW60. On multilayer film lines, PW60 is often added to the skin layers only. Addition rate depends on which layer is used and the layer thickness.
FOOD CONTACT STATUS
