DOUBLE BOND TAPE AND PRODUCTION OF DOUBLE BOND TAPE

摘要

PURPOSE: To prepare a double bond tape improved in adhesiveness and releasability to adherend due to the occurrence of penetration of an adhesive and provide a method for simply and inexpensively producing the tape. CONSTITUTION: A tacky agent layer 1 having 5-100μm thickness is provided on the both sides of a substrate 2 having unevenness face formed by embossing finish, having 20-200μm height of protruded part of the uneven face and 0.5-10mm maximum width of the protruded part and 0.5-10mm interval between the protruded parts. The objective double bond tape is obtained by directly applying an adhesive controlled to 100-20000cm poise viscosity to the substrate.
