Title:
熱収縮性ラベル用溶剤組成物、および熱収縮性ラベルの製造方法
Document Type and Number:
Japanese Patent JP7380721
Kind Code:
B2
Abstract:
Provided are a heat-shrinkable label and a package each having solvent bonded-portion where solvent penetration-through is not caused even when the film is thin. Provided are particularly a heat-shrinkable label and a package each having solvent bonded-portion gaining a high peel strength stability even when the film is passed through a tubing step made high in speed. A heat-shrinkable label has a tubular shape, in which both end portions of a heat-shrinkable polyvinyl chloride-based film or a heat-shrinkable polystyrene-based film are bonded to each other with a solvent composition. The solvent composition contains at least one organic solvent selected from the group consisting of tetrahydrofuran (THF), methyl ethyl ketone (MEK) and ethyl acetate, and at least one resin selected from the group consisting of polyester, polypropylene and hydrogenated petroleum resin, and the end portion bonded has a peel strength of 2 N/15mm or more.
