EASILY OPENABLE GAS BARRIER LAMINATE USING SOLVENTLESS ADHESIVE, AND EASILY OPENABLE GAS BARRIER PACKAGING MATERIAL AND EASILY OPENABLE PILLOW PACKAGING BAG COMPRISING THE LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a laminate excellent in easy openability and gas barrier properties and also excellent in bending resistance, and a packaging material using the laminate.;MEANS FOR SOLVING THE PROBLEM: The easily openable gas barrier laminate includes at least a substrate layer (A), a solventless gas barrier organic adhesive layer (B), a gas barrier inorganic vapor deposition layer (C), and an easily openable sealant layer (D). The gas barrier inorganic vapor deposition layer (C) and the solventless gas barrier organic adhesive layer (B) are laminated adjacently. The solventless gas barrier organic adhesive layer (B) is a layer formed by applying a two-pack curable solventless adhesive and curing it and has a thickness of 0.5-6 μm and a solvent content of zero or 6 mg/m² or less. The easily openable gas barrier laminate further includes a gas barrier coating film layer and a printing layer. The easily openable gas barrier packaging material uses the easily openable gas barrier laminate.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
