Abstract
There is provided a double-sided adhesive tape includes a foam base, a resin film disposed on a surface of the foam base, an adhesive layer disposed on a surface of the resin film, and an adhesive layer disposed on another surface of the foam base. The foam base has a density of 0.45 g/cm3 or less and an interlaminar strength of 10 N/cm or more. The adhesive layer has a 180°-peel adhesion of 10 N/20 mm or more. The 180°-peel adhesion is measured at a peeling speed of 300 mm/min when an adhesive tape including a 25-μm-thick PET base and a 25-μm-thick adhesive layer disposed on the PET base is bonded to an aluminium board at 23° C. and 65% RH by pressing the adhesive tape against the aluminium board with one stroke of a 2-kg roller and subsequently the adhesive tape is left standing for 1 hour at 23° C. and 50% RH.
