    摘要： A biaxially stretched heat-shrinkable laminated film is disclosed which possesses good heat-shrinkability, excellent melt hole resistance and heat-resistant sealing property (the heat resistance of a seal portion), and highly satisfactory cold resistance, retains transparency even after shrinkage, and serves advantageously as a wrap for packaging foodstuffs. The laminated film is provided as an oxygen barrier layer with a layer of a mixture of vinylidene chloride resin and a low melting point polyamide resin having a crystalline melting point of not higher than 210.degree. C. This mixed resin has been cross-linked by applying the electron beam to the laminate in a dosage in the range of 1 to 12 megarads. The laminated film exhibits a heat shrinkage percentage of not less than 15% at 90.degree. C. and excels in gas barrier property.

    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.

    摘要： The invention provides a heat-shrinkable multi-layer film comprising at least a thermoplastic resin layer as the outermost layer (A), a gas barrier resin layer as a core layer (B) and a sealing resin layer as the innermost layer (C), and optionally an adhesive layer between the individual layers, wherein (1) the sealing resin layer of the innermost layer (C) is a layer formed of a resin material (b) comprising a linear ethylene-1-octene copolymer (a) obtained by using a constrained geometry catalyst and having an 1-octene content not lower than 1 wt. % but lower than 20 wt. % and a density higher than 0.885 g/cm3 but not higher than 0.960 g/cm3, and (2) an intermediate layer (D1) formed of at least one resin (c) selected from the group consisting of polyamide resins, thermoplastic polyester resins and ethylene copolymer resins is provided between the outermost layer (A) and the core layer (B). The film has excellent sealing properties, clarity, mechanical strength, stretchability and bag-making property.
