发明名称 アルコール含有物用包装袋
摘要 PROBLEM TO BE SOLVED: To provide a packaging bag for an alcohol inclusion which is used for packaging liquid having an alcohol concentration of 50 mass% or more, or a matter impregnated with the same, formed by heat-sealing a laminate, has excellent alcohol resistance and satisfactory cutting properties by hands when opening the bag, capable of reducing the discharge amount of an organic solvent when the laminate used for the bag is produced, excellent in property and use suitability, and does not give adverse influence to environment.SOLUTION: The laminate is formed by laminating a base material layer 1, an adhesion layer 2, a barrier layer 3, an anchor coat layer 4 and a polyolefin based resin layer 5 in this order. The barrier layer is formed by depositing an aluminium foil or the like on a base material film. The anchor coat layer is formed by applying an aqueous dispersion liquid of a polyolefin polymer resin, which contains 0.01 to 5 mass% of an unsaturated carboxylic acid or an anhydride thereof and has an average particle diameter of 1 μm or less, to form a dry film having a thickness of 0.1 to 2 μm on a surface of the barrier layer, and thereby, the alcohol resistance is improved. The polyolefin based resin layer is formed by laminating a polyolefin based resin on the anchor coat layer, and recesses and projections having a height of 7 to 20 μm are formed on the surface thereof to improve the cutting properties by hands.SELECTED DRAWING: Figure 1
