PW52, PW60 and PW66 are 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 PW52, PW60 or PW66 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 24-72 hours.
In LLDPE : PX 004 V is designed to make LLDPE stretch film by either blown film or cast film process. Its cling properties give low noise and low static when unwinding film rolls and will not cause any problem of roll telescoping after production. It produces a cling film that is pleasant to touch in comparison with films made with other cling agents. PX 004 is compatible with most polyolefins, but not EVA. PE resins used in any stretch-cling film composition must not contain any slip or antiblock additives.
In PA : PX 004 V is used in PA to improve surface finish of molded parts (especially mineral filled grades), to assist processing of complicated molded parts and to increase impact strength (especially falling weight impact).
