摘要
A laminated barrier film which is harmless to the environment and combines the property of being easily tearable with moderate barrier properties. The laminated film comprises: an easily tearable barrier film (19) which is made up of a first layer (23) to a third layer (25), has undergone stretching in a stretch ratio of 2.8 or higher in each of the machine and transverse directions, and has undergone thermal fixing by heat treatment at 120 to 195° C. so that it has a shrinkage of 15 to 40% through 20-minutes immersion in pressurized 120° C. water; and a sealant film (21) laminated to the film (19). The first layer (23) and the third layer (25) each contains 60 to 85 parts by weight of Ny6, 15 to 40 parts by weight of MXD6, and 0.1 to 10 parts by weight of a modifier, while the second layer (24) contains 0 to 40 parts by weight of a thermoplastic resin such as Ny6, 60 to 95 parts by weight of MXD6, and 0.1 to 10 parts by weight of a modifier.
