BASELESS DOUBLE-SIDED ADHESIVE TAPE AND METHOD OF PRODUCING THE SAME, AND ADHESIVE ROLL AND METHOD OF PRODUCING THE SAME

PURPOSE: A non-carrier double sided adhesive tape stably prevents an end part from being cut by having a large difference between heavy peeling force and light peeling force. CONSTITUTION: A non-carrier double sided adhesive tape (10) includes a light-peelable sheet (1), a substrateless adhesive lay...

Zusammenfassung:PURPOSE: A non-carrier double sided adhesive tape stably prevents an end part from being cut by having a large difference between heavy peeling force and light peeling force. CONSTITUTION: A non-carrier double sided adhesive tape (10) includes a light-peelable sheet (1), a substrateless adhesive layer (2) and a heavy-peelable sheet (3). On one main side of the substrateless adhesive layer, the peeling side of the light-peelable sheet is attached, and on the other main side of the sustrateless adhesive layer, the peeling side of the heavy-peelable sheet is attached. The peeling force of the light-peelable sheet and the peeling force of the heavy-peelable sheet satisfy a formula 1: FH-FL >= 10 mN/50mm. The peeling side of the light-peelable sheet has a region on which the substrateless adhesive layer is not laminated at both ends.
