Title:
結露抑制包装容器、青果物入り包装体および青果物の鮮度劣化抑制方法
Document Type and Number:
Japanese Patent JP7423902
Kind Code:
B2
Abstract:
To provide a dew condensation suppression packaging container which has an excellent heat sealing property, and which is hardly broken by an external force.SOLUTION: A dew condensation suppression packaging container is constituted by a resin film. The resin film includes a base material layer and a heat seal layer provided on one surface of the base material layer. A tensile modulus of elasticity of the resin film measured by a tensile test at a tensile speed of 2 mm/minute is 300-1200 MPa. The moisture permeability of the resin film at 40°C, 90%RH is 50-350 g/(m2 24h). The melting point of the heat seal layer is lower than the melting point of the base material layer by 15°C or more.SELECTED DRAWING: Figure 1
