GAS BARRIER LAMINATE FOR USE IN HOT WATER TREATMENT

摘要

A gas barrier laminate for use in hot water treatment, comprising a plastic base film, a coating layer formed on at least one surface of the plastic base film, an inorganic thin film comprising a metal compound and formed on the surface of the coating layer and a heat-sealable plastic film laminated on the inorganic thin film or the plastic base film, the inorganic thin film without the heat-sealable plastic film laminated thereon showing an abrasion strength of 20 runs or more at a load of 70 g, the coating layer having a hardness of 0.15 to 0.40 GPa. The laminate is excellent in interlayer close-adhesion, hardly causes the breakage of the inorganic thin film by hot water treatment, and can retain an excellent gas barrier property even after hot water treatment.
