    摘要： A polyamide resin-based heat-shrinkable multilayer film is caused to satisfy various properties required of a packaging material, especially a food packaging material, at high levels, and particularly exhibit a highest level of heat-shrinkability. The multilayer film comprises at least three layers including an outer surface layer (a) which comprises a polyester resin or a polyolefin resin; an intermediate layer (b) which comprises a mixture of 85-60 wt. % of an aliphatic polyamide resin, and 15-40 wt. % of an aromatic copolyamide resin which is a copolymer of aliphatic diamine/isophthalic acid and aliphatic diamine/terephthalic acid, and an inner surface layer (c) which essentially comprises a copolymer of ethylene and &agr;-olefin having a density below 0.915. The heat-shrinkable multilayer film has been biaxially stretched and then heat-treated to have hot-water shrinkabilities at 80° C. of at least 30% in each of longitudinal/transverse directions and at least 35% in at least one of longitudinal/transverse directions.

    摘要： A laminate resin film having two major surfaces is constituted by plural resin species. In the laminate, layers of the plural resin species are laminated obliquely to the two major surfaces in at least one section perpendicular to the two major surfaces, and each layer of the plural species of resins is exposed to the two major surfaces. The laminate resin film has equivalent properties in the thickness direction (such as gas-barrier property) as in a conventional laminated film but has properties in the planar extension direction which are remarkably affected by properties (such as low Young's modulus and heat-shrinkability) of a certain component resin layer.
