PIB60 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 PIB60
must notcontain 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 4%-8% PIB60by weight should be added to LLDPE ( or resin mix). For monolayer Cast
films 2% and 4 % PIB60. On multilayer film lines,PIB60is often added to the skin layers only. Addition rate
depends on which layer is used and the layer thickness.
