FERROCLING PW 60 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 FERROCLING PW 60 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 ís 24-72 hours.

 
Recommended Addition Rates
  • For monolayer blown films 8 % FERROCLING PW 60 by weight should be added to LLDPE (or resin mix).
  • For monolayer cast films 3 and 4 % FERROCLING PW 60.
  • On multilayer film lines, FERROCLING PW 60 is often added to the skin layers only.

Addition rate depends on which layer is used and the layer thickness.

 
Food Contact Status
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.
