ABSTRACT:
In a foodstuff container of the type comprising a cylindrical body of a laminated sheet and lids closing the opposite ends of the cylindrical body, the laminated sheet is made up of two outer layers made of a thermoplastic resin consisting essentially of a synthetic resin having a melting point higher than 115.degree. C., a paper layer and an aluminum foil. The opposite side edges of the laminated sheet are covered by tape shaped aluminum foils with both surfaces coated with a thermoplastic resin similar to that of the laminated sheet, and one ends of both of the tape shaped aluminum foils are bent back to face the inner surface of the container. The tape shaped aluminum foils and the opposite side edges of the laminated sheet are welded together to form the cylindrical body.
