Title:
PACKAGING BAG FOR ADHESIVE SKIN PATCH
Document Type and Number:
Japanese Patent JP2013100134
Kind Code:
A
Abstract:

To provide a packaging bag for a sheet-like adhesive skin patch containing a skin-permeable drug such as an analgesic antiphlogistic, wherein a packaging bag for an adhesive skin patch can withstand a preservation test at 60°C for two weeks as an acceleration test for content preserving properties, has a good hand-tearable property when the bag is opened after the preservation, and can decrease the amount of discharging of organic solvents when a laminate used for the bag is manufactured.

A packaging bag for an adhesive skin patch is formed by heat-sealing the laminate prepared by laminating at least a substrate layer, an adhesive layer, a barrier layer, an anchor coat layer (AC layer), and a polyolefin resin layer in this order. The AC layer of the laminate is formed by applying a barrier layer surface with a water-based dispersion in which a polyolefin copolymer resin containing 0.01-5 mass% unsaturated carboxylic acid or its anhydride is dispersed into a number-average particle size of ≤1 μm without using a nonvolatile water-compatibilizing agent with a thickness of 0.1-2 μm, and drying it by heating, and the polyolefin resin layer is laminated on the AC layer by an extrusion coating method or an extrusion laminating method.
