Embodiment 1
[0146] Block PP (PC480A, manufactured by SunAllomer Ltd., MFR=1.7 (230° C., 2.16 kgf)) as the substrate layer and an α-olefin-based pressure-sensitive adhesive (Tafthren H5002, Sumitomo Chemical Company, Limited) was loaded into an extruder, and then melt-extruded by an inflation molding method. Thus, a laminate (1) for a non-aqueous battery (thickness: substrate layer / pressure-sensitive adhesive layer=30 μm / 10 μm) was produced.
[0147]Table 1 shows the evaluation results.
Embodiment 2
[0149] Block PP (PC480A, manufactured by SunAllomer Ltd., MFR=1.7 (230° C., 2.16 kgf)) as the substrate layer and 100 parts by weight of α-olefin-based pressure-sensitive adhesive (Tafthren H5002, manufactured by Sumitomo Chemical Company, Limited) and 30 parts by weight of ARAKAWA CHEMICAL INDUSTRIES, Ltd. The product obtained by mixing the tackifier "ARKON P-125" was charged into the extruder, and then passed through the blown Molding method for melt extrusion. Thus, a laminate (2) for a non-aqueous battery (thickness: substrate layer / pressure-sensitive adhesive layer=30 μm / 8 μm) was produced.
[0150] Table 1 shows the evaluation results.
Embodiment 3
[0152] Block PP (PC480A, manufactured by SunAllomer Ltd., MFR=1.7 (230° C., 2.16 kgf)) as the substrate layer and 100 parts by weight of α-olefin-based pressure-sensitive adhesive (Tafthren H5002, manufactured by Sumitomo Chemical Company, Limited) and 15 parts by weight of ARAKAWA CHEMICAL INDUSTRIES, Ltd. The product obtained by mixing the tackifier "ARKON P-125" was charged into the extruder, and then passed through the blown Molding method for melt extrusion. Thus, a laminate ( 3 ) for a non-aqueous battery (thickness: substrate layer / pressure-sensitive adhesive layer=30 μm / 8 μm) was produced.
[0153] Table 1 shows the evaluation results.
