Stretch Cling Flim Masterbatches(PW 70)
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 PW70
must not contain any slip or antiblock additive ives or have a density higher than 0.923 as this will prevent the
migration of the cling additive.
RECOMMENDED ADDITION RATES
For monolayer blown films 6 % PW 70 by weight should be added to LLDPE (or resin mix). For
monolayer Cast films we recommend between 2 and 3% of PW 70. On multilayer film lines, PW 70 is
often added to the skin
layers only. Addition rate depends on which layer is used and the layer thickness
