IRRADIATED LAMINATE FILM HAVING HEAT SEALING CHARACTERISTICS Abstract A coextruded irradiated film has a crosslinked layer and a heat sealable layer. The crosslinked layer is crosslinked by irradiation at a dosage level sufficiently low that the heat sealing properties of the heat sealable layer are not adversely affected. The crosslinked layer is crosslinked to a desirable level due to the presence of irradiation crosslinking enhancers which are incorporated within the crosslinked layer so as to promote crosslinking at a low dosage level.
