Abstract
Adhesive tape is manufactured by laminating at least one layer of a heat activated adhesive film to one layer of a substrate material, and coating the thereby obtained laminate with a pressure sensitive adhesive. Because the substrate is laminated with a film, typically a random copolymer of ethylene and acrylic acid, the adhesive which is thereafter coated on the laminate will not flow through the substrate, even if a porous substrate is used.
