Document Type and Number:
Japanese Patent JP6860851
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laminate for boil sterilization that can be used in producing a packaging bag for boil sterilization excellent in boil sterilization resistance and hand tearability, while improving a biomass degree.SOLUTION: A laminate for boil sterilization 10 includes at least a first substrate layer 11, a second substrate layer 12 and a sealant layer 13 in this order. The first substrate layer 11 includes a polyethylene terephthalate. The second substrate layer 12 includes a polyamide. The sealant layer 13 includes a linear low-density polyethylene derived from a biomass and a low-density polyethylene. A content of the low-density polyethylene in the sealant layer 13 is 5-25 mass%. The sealant layer 13 includes a linear low-density polyethylene derived from a fossil fuel. The linear low-density polyethylene derived from biomass and/or derived from a fossil fuel is 75-95 wt.% in total. The laminate for boil sterilization is capable of producing a packaging bag excellent in boil sterilization resistance.SELECTED DRAWING: Figure 1
