  • LAMINATE AND STAND-UP POUCH
    Publication number: 20230339219
    Abstract: The present invention relates to a laminate including a protection layer, a barrier layer, and a heat sealing layer, in which a product of a tensile elastic modulus A in a reference direction, a tensile elastic modulus B in a direction forming an angle of 45° with respect to the reference direction, and a tensile elastic modulus C in a direction forming an angle of 90° with respect to the reference direction is 0.22 (GPa)3 or less, and a value of the tensile elastic modulus B to the tensile elastic modulus A, a value of the tensile elastic modulus C to the tensile elastic modulus A, and a value of the tensile elastic modulus C to the tensile elastic modulus B are each 0.1 to 10.
    Type: Application

  • Multilayer structure, and standup pouch including the multilayer structure
    Patent number: 11738543
    Abstract: A multilayer structure includes a protective layer, an ethylene-vinyl alcohol copolymer layer, a heat seal resin layer, and an intermediate layer provided between the ethylene-vinyl alcohol copolymer layer and the heat seal resin layer and containing a polypropylene resin, wherein the intermediate layer further contains a hydrocarbon resin having a number average molecular weight of 100 to 3,000, and a softening point of not less than 60° C. and less than 170° C. The multilayer structure satisfies requirements for a lower water vapor permeability and a sufficient heat seal strength, and provides a standup pouch having a smaller gas barrier property change rate after retort treatment.
