POLYMER-METAL LAMINATION BY RADIATION METHOD

Conventional technology of PE-metal laminate involves the use of adhes ives for laminating. Environ pollution has been a big problem not easi ly resolved and processing is complicated. By radiation peroxidation o f the surface of polyethylene a simple polyethytene-metal laminating m ethod has been succeeded. Measurements of the mechanical properties an d the electrical properties made according to China's national standar ds showed the properties of the laminating film conforming well with t he national standards. It has been found that the adhesion strength of the PE-metal film is affected by irradiation, the metal surface react ivity and cleaning of the laminating surface. PE-metal film laminated by radiation method is more heat resistant than the film laminated by conventional methods. The laminate materials can be widely used in ele ctrical devices, chemical and packaging industry.
