Abrégé

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/15mm or more.
