ABSTRACT:
To provide a laminate adhesive that can keep on having adequate adhesiveness and also can prevent the odor and taste of the inherent properties of the content packed by the packing product from being spoiled even after high temperature sterilization treatment, such as the hot-water spray sterilization treatment, the hot-water rotary sterilization treatment or the steam sterilization treatment, to provide a usage of the laminate adhesive, the laminate adhesive comprises a curing component containing polyisocyanate and a base component containing polyol, wherein a silane coupling agent is contained in at least the curing component. Preferably, the silane coupling agent is mixed with both of the curing component and the base component. Further preferably, epoxysilane is mixed with the curing component and also aminosilane and oxyacid of phosphorus or derivative thereof are mixed with the base component.
