。 At the heat-sealed surface of the longitudinal side end,
It is composed of a laminate having a sealant layer having a cohesive failure property on at least one side end thereof and having a heat-shrinkable plastic film as a base material, and the laminate is easily formed by a body seal. In the openable heat-shrinkable package, the sealant layers at the side ends or the sealant layer at one side end and the other side end that are heat-sealed to have a strength higher than the cohesive failure strength are bonded in the longitudinal direction. Forming an easily openable close heat-sealed portion at the side end portion, forming a close seal portion at the upper and lower ends, and providing a peel initiation portion that is not heat-sealed at the longitudinal side end portion or the upper and lower end portions. In a package that is filled with contents and then heat-shrinked by a heating means after being sealed, when opening the package, almost all of the easy-to-open heat-sealed portions are opened and expanded so that the packaged contents cannot be accessed by hand. An easy-to-open heat-shrinkable package that can be used without touching the package.
