A vinyl chloride copolymer foam plastisol with an epoxidized natural oil plasticizer such as epoxidized soybean oil and a blowing agent, the plastisol having a long shelf life and the plastisol easily being applied as a liner to the underside of a closure top and fused, without preheating, at a relatively low temperature of about 300 DEG C. for a short time of about 90 to 120 seconds to form a foam liner, the solidified foam plastisol having resilience, good tensile and elongation properties to thereby provide a stable gasket assembly.
