A nylon/olefin polymer especially nylon/polyethylene laminate film is useful for packaging food to be cooked in hot water. However, special steps are required to bond the nylon and olefin polymer firmly enough to prevent delamination in these severe conditions. Various adhesives have been tried and in particular combinations of use of an ionomer as adhesive and irradiation of the laminate film. However, a high dosage of radiation is required. The solution to this problem provided by the present invention involves use as an adhesive of an ethylene-vinyl acetate copolymer and irradiation of the laminate film. A dosage as low as 2.0 megarads is possible using this adhesive. |
