TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Foil: The metallic foil is aluminum foil (5) having thickness of 5-100 microns.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Foil: The metallic foil is aluminum foil (5) having thickness of 5-100 microns.    TECHNOLOGY FOCUS - POLYMERS - Preferred Layer: The heat-bondable resin layer contains linear ethylene-based copolymer obtained by co-polymerizing ethylene (70-99 wt.%) and (alpha)-olefin (30-1 wt.%), preferably 3-12C alpha-olefin using a metallocene compound as a catalyst. The binding layer (C) is polypropylene-resin layer having melting point of 120-150degreesC. The heat-bondable resin layer has wetting tensile strength of 38-54 mN/m. The biaxially-oriented polypropylene layer contains organic-type particle having average particle diameter of 0.5-10 microns. Preferred Properties: The linear ethylene polymer has density of 0.87-0.905 g/cm3 and melt flow rate of 2-150 g/10 minutes. Preferred Film: The polypropylene film has polypropylene layer (1) on biaxially-oriented polypropylene layer (2). The polypropylene layer (1) has thickness of 0.5-3 microns and ethylene copolymerization amount of 0.1-5 wt.%, and contain organic-type particle having average particle diameter of 0.5-10 microns. Preferred Particle: The organic-type particle is cross-linked silicone-resin particle, cross-linked polystyrene resin particle and/or cross-linked acrylic-resin particle. EXAMPLE - Biaxial polypropylene layer containing zeolite particle (1100 ppm) and having intrinsic viscosity of 1.9 dl/g, and ethylene propylene butene copolymer containing ethylene (3.5 wt.%), butene (4 wt.%) and silicone particle (4000 ppm) having average particle diameter 2 microns, were melt-extruded and solidified by cooling to obtain a laminated sheet. The sheet was pre-heated and drawn at 135degreesC and draw ratio of 4.5 times in longitudinal direction to obtain uniaxially stretched oriented film. The film was heated and drawn at 160degreesC and a draw ratio of 10 times in horizontal directions to obtain biaxially stretched polypropylene film. The polypropylene film had wetting tensile strength of 40 mN/m. The thickness of resin layer, base layer and binding layer are 1 microns, 13 microns and 1 microns. The heat bonding resin layer containing silicone particle had melting point peak of 60degreesC and 114degreesC, and wetting tensile strength of 42 mN/m.
