Title:
WATER-SOLUBLE FILM AND MEDICINE PACKAGE
Document Type and Number:
Japanese Patent JP2017100806
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a water-soluble film which has good heat sealability that adhesion, strength and the like in a heat seal portion are excellent even at a low heat seal temperature when a package is formed, and is excellent in productivity, and to provide a medicine package formed by packaging various medicines with the water-soluble film.SOLUTION: A water-soluble film which contains a PVA-based resin (A), has a breaking strength (X1) of 11.0 N/15 mm or more, when two water-soluble films overlap each other of which humidity is adjusted under environments of 23°C and 40%RH for one day, the overlapped water-soluble films is heat-sealed once under environments of a temperature of 140°C, a pressure of 0.65 MPa, a time of 1.5 times, and a seal width of 1.5 mm, then the heat sealed film is left for 2 hours under environments of 23°C and 40%RH, and the heat seal portion is peeled; and prevents interfacial peeling during peeling. A water-soluble film which contains a PVA-based resin (A), and has a breaking strength (X2) of 11.5 N/15 mm or more, when two water-soluble films overlap each other of which humidity is adjusted under environments of 23°C and 40%RH for one day, the overlapped water-soluble films is heat-sealed once under conditions of a temperature of 145°C, a pressure of 0.65 MPa, a time of 1.5 times, and a seal width of 1.5 mm, and the heat sealed film is left for 2 hours under environments of 23°C and 40%RH, and the heat seal portion is peeled; and prevents interfacial peeling during peeling.SELECTED DRAWING: None
