LID FOR A FOOD CAN

摘要

A lid for a food can, comprising a body layer (2) made of paper, a plastic layer composite (4, 5, 6) extruded onto that surface of the body layer that faces the can and, attached to the plastic layer composite, a peelable heat-sealing layer (7) for fastening the lid (1) to the can by heat-sealing. According to the invention, the heat-sealing layer comprises a layer (7) of heat-sealing lacquer, and the plastic layer composite comprises, adjacent to the paper layer (2), a first plastic layer (4) made of acid-modified ethylene-based copolymer; adjacent to the first plastic layer, a second plastic layer (5) made of plastic that is infusible at the heat-sealing temperature used; and between the second plastic layer (5) and the heat-sealing lacquer (7), a third plastic layer (6) made of acid-modified ethylene-based copolymer.
