Реферат: The present invention provides a method of lining a plastic closure top with a thermoplastic, non-cross linked curable, vinyl chloride copolymer plastisol composition that is plasticized with an effective low temperature fusing amount of (A) an epoxydized natural oil, (B) an organic diglycidyl ether and (C) a curing agent for the diglycidyl ether, the plastisol being stable with a shelf life of at least about four months, the method including heating, without preheating, the lining and the closure top at a temperature not over about 300°F for about 90 to 120 seconds using convection heating without pressure and without conductive heating, to fuse the composition and thereafter solidifying the fused composition and thereafter cure the composition to provide the lining with tensile and elongation measurements sufficient for a stable closure assembly.
