POLY(4-METHYL-1-PENTENE) RESIN LAMINATES AND USES THEREOF

摘要

A poly(4-methyl-1-pentene) resin laminate essentially constituted of a layer made from a 4-methyl-1-pentene polymer (A), an interlayer made from an adherent resin composition (B) and a layer made from a propylene polymer composition (C) comprising 60 to 90 parts by weight of a propylene polymer (c-1) and 10 to 40 parts by weight of a 1-butene polymer (c-2), which is excellent in heat-sealing properties, oxygen gas permeability and blocking resistance and therefore usable as freshness-keeping wrapping material, culture vessels and so on. Another poly(4-methyl-1-pentene) resin laminate essentially constituted of a layer made from a 4-methyl-1-pentene polymer (A'), an interlayer made from an adherent resin composition (B') and a layer made from an olefin polymer (C'), which is usable as the material of containers for keeping the freshness of fruit and vegetables.
