PEELABLE HEAT SEALS AND METHOD FOR MAKING SAME

摘要

A heat sealed package including a first package wall having an inner surface and an outer surface and a second package wall having an inner surface and an outer surface. The first package wall is formed of spunbonded olefin. The second package wall i ncludes an inner layer laminated to an outer layer. The inner layer is formed of a blen d of polybutylene and one other constituent. The other constituent preferably comprises a 2% e thylene vinyl acetate copolymer of polyethylene. The inner layer forms the inner surface o f the second package wall and is heat sealed to the inner surface of the first package wa ll to form an object receiving chamber. The first package wall is joined to the second pac kage wall by the heat seal such that the first package wall can be peelably removed from the second package wall without tearing of the first package wall.
