PURPOSE: To make it possible to tear off a laminated packaging material linearly by hands without providing further a stretched polyethylene layer having excellent linear cut properties or an unpacking assist member, in regard to the laminated packaging material using a nylon film having an excellent impact resistance.
CONSTITUTION: In regard to a laminated packaging material prepared by laminating a nylon film 1 and a heat-sealing resin layer 2 sequentially, a biaxially stretched film constituted of aromatic polyamide and 6-nylon is used as the nylon film 1. An outer layer may be laminated on the surface of the nylon film on the opposite side to the heat-sealing resin layer. It is preferable, besides, that a gas barrier layer is provided between the nylon film 1 and the outer layer or the heat-sealing resin layer 2. These layers are laminated preferably by a dry lamination method using a bonding agent of urethane series.
