PROBLEM TO BE SOLVED: To provide a packaging body which is excellent in heat sealability, and has both excellent easy-opening properties and excellent resealing properties only by pressure contact bonding using a hand or a finger, and can be resealed, even when a heat seal resin of a lid material or a bottom material of a packaging body being a body to be sealed is an amorphous polyester resin.MEANS FOR SOLVING THE PROBLEM: There is provided a packaging body using a film which is a packaging body that is exposed in a state where both an adhesive resin layer (B) and a peeling resin layer (C) can be resealed when the layers (B) and (C) are delaminated, in a multilayer film formed by sequentially laminating a surface resin layer (A), the adhesive resin layer (B), the peeling resin layer (C), and a heat seal resin layer (D). The adhesive resin layer (B) is formed so as to contain a styrene-based thermoplastic elastomer having a temperature indicating a peak value of a loss tangent (tanδ) of dynamic viscoelastic measurement of -35°C or higher, as a main component. The peeling resin layer (C) is formed so as to contain a polyester-based resin as a main component. The heat seal resin layer (D) is formed of a layer formed so as to contain an amorphous polyester resin as a main component.SELECTED DRAWING: Figure 2 |
