HTM 1640 B is an antiblocking masterbatch that contains a special no-migrating organic additive in a polypropylene copolymer carrier. It is approved for food contact applications by both FDA and EU.
HTM 1640 B contains a special polymeric agent which offers steady antiblocking performance as time goes by, as a noticeable decrease of the COF in coextruded films without the necessity of adding any else additive.
Making use of HTM 1640 B does not cause dust release at the downstream slitting process.
Provides the film with a smooth surface, ideal for metallizable films.
HTM 1640 B is especially appropriated in those cases when masterbatches containing synthetic silica cause marks, grooves and scratches as the film slides on metallic surfaces and when low COF is demanded.
