摘要：
The present invention relates to a multilayer sheet comprising:
at least one sealant layer comprising:
from 0.02 to less than 1 percent by weight of one or more antimicrobial agents, based on the total weight of the sealant layer;
at least 20 percent by weight of a base polymer, based on the total weight of the sealant layer, wherein said base polymer comprises a propylene/α-olefin copolymer composition, wherein said propylene/α-olefin copolymer has a crystallinity in the range of from 1 percent by weight to 30 percent by weight and a heat of fusion in the range of from 2 Joules/gram to 50 Joules/gram;
from 10 to 80 percent by weight of a secondary polymer selected from the group consisting of polypropylene homopolymer, polypropylene random copolymer, impact modified polypropylene, and combinations thereof;
at least one core layer in contact with said at least one sealant layer, wherein said core layer comprises a core polymer.
at least one sealant layer comprising:
