ABSTRACT:
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.
