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/15 mm or more.

Abstract: Provided are a heat-shrinkable polyester-based label, and a package which each have a solvent-bonded portion where no solvent permeation-through is caused even when a film of the label is small in thickness. Provided are, in particular, a heat-shrinkable polyester-based label and a package which each have a solvent-bonded portion giving a high peel strength stably even through a high-speed tubing step, or even when the film is a heat-shrinkable polyester-based film in which a PET-bottle-recycled material is used in a large proportion. The label is a heat-shrinkable polyester-based label that is a tubular label in which both end portions of a heat-shrinkable polyester-based film are bonded to each other with a solvent composition. In this label, the solvent composition is a solvent composition containing at least 1,3-dioxolane and/or tetrahydrofuran (THF), and a polyester, and the end portion bonded has a peel strength of 2 N/15 mm or more.
