Propylene polymer based compounds and heat-sealable multi-layer sheets containing them |
摘要 |
A polypropylene composition is disclosed, having a sealing initiation temperature below 80° C., and containing less than 1% by weight of monomeric units derived from ethylene with respect to the total weight of the composition, and comprising:-from 35 to 68% by weight of a random copolymer of propylene (copolymer (A)) containing 16 to 30% by weight of monomeric units derived from I-butene and from 0 to 0.5% by weight of monomeric units derived from ethylene with respect to the total weight of copolymer (A), and-from 65 to 32% by weight of a random copolymer of propylene (copolymer (B)) containing 35 to 55% by weight of monomeric units derived from I-butene and from 0 to 1% by weight of monomeric units derived from ethylene with respect to the total weight of copolymer (B). Heat-sealable sheets containing a sealing layer of the above composition are also disclosed.
