Abstract
Process and apparatus for bonding shaped members without the use of an adhesive, comprising the steps of exposing the surfaces to be bonded to the low energy particles of a gas discharge plasma just before and substantially simultaneously as the members are brought together into intimate face-to-face contact; heating the members; and then compressing the heated members together. The process is applicable to bonding a thermoplastic resin such as polyethylene or ethylene-vinyl acetate copolymer to a wide variety of materials including cellophane, polyester or aluminum foil.
