Tackify/PIB masterbatch is a concentrate of high molecular weight Polyisobutylene tackifier in Linear Low Density. It is used as a cling agent to make stretchwrap films from LLDPE or LDPE. The high PIB content achieves its excellent cling property. 

Tackify/PIB masterbatch is designed to produce stretchwrap films from LLDPE, LDPE for the applications of palletwrap, silagewrap. It can be used on either blown film or cast film process. Polymers used with PIB masterbatch must not contain any Anti blocking additive, slip agent as this will prevent the migration of cling additive. Migration time for good cling properties is usually 24 to 72 hours.
