The effect of process parameters of heat contact welding of three-layer films based on polyethylene terephthalate and polyethylene with adhesive layers of modified ethylene-vinyl acetate copolymers on the strength properties of the weld is studied. The optimum welding conditions are determined. The dependence of the strength of the T-shaped weld on the thickness of the adhesive layer when duplicating the polar and non-polar polymers is established . .
