摘要： A packaging sheet for containing foodstuff is proposed which comprises a substrate of synthetic resin and a metallic film layer laminated to the substrate through an adhesive layer and a resin layer having a lower bond strength than the adhesive layer. Food packaging containers using the packaging sheet as a lid and self-standing pouches using the packaging sheet as their side sheets are also proposed. Before such a container or pouch containing food is put into a microwave oven for cooking, the metallic film layer or layers can be removed easily from the substrate.

摘要： Laminates comprising a film of heat-shrinkable synthetic resin and a metallic foil laminated to the resin film through a bonding layer which comprises a discontinuous layer of a synthetic resin which does not flow at a temperature for heat shrinkage and an adhesive layer which maintains its adhesive strength at the temperature. Upon heat shrinkage, the metallic foil will wrinkle at the discontinuous layer portions because the synthetic resin is hardly adhesive at the temperature for heat shrinkage. The heat-shrunk laminate can be formed into a casing or container such as an electromagnetic interference shields, packaging material, and decorative material.

摘要： An improved packaging container comprising a container body (30) and a lid (40) heat-sealed to the container body is proposed which is retortable and has a high peel strength and a good easy-openability. The heat-sealed portion is formed with a groove (41) having a sectional shape gradually deepening from its outer edge (42) toward its inner edge (43), the inner edge (43) extending in a smoothly curved line while the outer edge (42) extends in a zigzag line. This ensures high peel strength against the force applied from inside of the heat-sealed portion and a good easy-openablility from outside of it.
