Adhesive comps. used esp. for heat-sealing of PVC and polyalkens or metals contained mixts of PVC or vinyl chloride copolymer and chloriated polyethylene. Thus, a 250 thick PVC film was coated with an adhesive compn. contg. vinylacetate-vinyl chloride copolymer 50, chlorinated polyethylene 50, a Ca=Zn soap, phMe 500, and AcOEt 500 parts and heat-sealed for 2se- at 150≦̸C under 2kg/cm2 with an 80 thick polyethylene film to give a laminate.
