PW 60 by Polytechs is a high molecular weight polyisobutylene tackifier concentrate in linear low density polyethylene. It is used as a cling agent. 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. Migration time for good cling properties is 24-72 hours. For monolayer blown films 8% PW 60 by weight should be added to LLDPE (or resin mix) and 3-4% for monolayer cast films. PW 60 complies with FDA 21 CFR 117.1430 and FDA 21 CFR 177.1520 for use in contact with food and also meets the requirements of EC Directive 90/128/EEC and EC Directive 94/62/EC.
