The electron pre-irradiation of polyethylene powder and subsequent reaction with acrylic acid for modifying adhesive property of polyethylene were investigated. The dependences of melt index
gel content
surface tension and polyethylene/A1 foil adhesion on irradiation dose and acrylic acid content were measured. It was shown that adhesion between the grafted polyethylene and aluminium foil
as measured by a "180°" peel-test
reached the value of 2.45N/2.5cm. This material can be developed to produce laminate for food packing. The possible mechanism of graft modification was discussed. "H" and "T" graft models were proposed.
