Abstract
A process for manufacturing a flat adhesive tape comprises: providing a stiff interfacial sheet having a flat and solid form; surrounding the stiff interfacial sheet with a plurality of adhesive layers so as to form a roll of the adhesive layers with the stiff interfacial sheet positioned on a symmetric plane of the roll; and compressing the roll to form the flat adhesive tape. The stiff interfacial sheet can have a length slightly longer than a half-length of an innermost circumference of the roll of the adhesive layers. A layer of high adhesion material containing uncured high cross-linking epoxy or uncured high cross-linking cyanoacrylate can be provided between the stiff interfacial sheet and the adhesive layers. After compressing the roll of the adhesive layers, the high adhesion material is cured to form the flat adhesive tape.
