Abstract

A process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls. Also, a process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; disposing a barrier film onto the dried adhesive; casting a liquid plastisol formulation onto the barrier film; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the barrier film; and, winding the resulting tape laminate onto rolls.
