PW 66

Technical Datasheet | Supplied by Polytechs
A cling masterbatch containing concentrate of Polyisobutylene (PIB) of an average molecular weight of 1250 in Linear Low Density Polyethylene. It is used as a cling agent to make stretchwrap films from LLDPE or LDPE. It is a dry free-flowing pellet. It 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 66 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 24-48 hours. For monolayer blown films, 7% of PW 66 by weight should be added to LLDPE (or resin mix). For monolayer cast films 3% of PW 66 should be added. On multilayer film lines, PW 66 is often added to the skin layers only. Addition rate depends on which layer is used and the layer thickness. Polyisobutylene is allowed by the FDA for use in contact with food (21 CFR 117.1430) and also meets the requirements of EC Directive 90/128/EEC.
