MULTILAYERED HEAT-SEALABLE PLASTIC FILM

摘要

The invention relates to a heat-sealable plastic film for hermetically sealing plastic containers, comprising at least two layers which mutually adhere, (i) a support layer comprised of an impact resistant polystyrene resin and (ii) a sealing layer comprised of 20-100 weight % of a copolymer P consisting essentially of: p1) 20-90 weight % methyl methacrylate and/or ethyl methacrylate; p2) 10-80 weight % of at least one monomer of formula I <IMG> (I), where R1 represents an C3-24 alkyl group; and p3) 0-10 weight %, preferably 1-8 weight %, of a monomer which is copolymerizable with and different from the monomers (p1) and (p2).
