PROBLEM TO BE SOLVED: To provide a package excellent in food hygiene, and having excellent opening properties, excellent resealing properties only by crimping with the finger, and a mischief/alteration preventing function.SOLUTION: A package is such that in a multilayer film in which a surface resin layer 3, an adhesive resin layer 4, a peeling resin layer 5, and a heat seal resin layer 6 are stacked in this order, the layer has as the main component, styrenic thermoplastic elastomer having a temperature showing a peak value of loss tangent (tanδ) of equal to or more than -35°C, the layer 5 has as the lid material or bottom material, a multilayer film with a resealable function, comprising a layer formed of cyclic olefin resin of a glass-transition temperature (Tg) of 100-150°C, and the bottom material and the lid material are heat-sealed by heat sealing the heat seal resin layer 6 of the multilayer film to a heat seal part of a body to be sealed. Furthermore, in the resealable package, when the layer 4 and the layer 5 are separated between the layers in the heat seal part, both layers expose in a resealable state. |
