<p>PROBLEM TO BE SOLVED: To prepare a non-halogen pressure-sensitive adhesive tape which is prevented from the deterioration of its external appearance caused by 'whitening' of a substrate film layer due to a white inorganic flame-retardant and, at the same time, improve in the heat resistance of its outer film layer. SOLUTION: In the non-halogen pressure-sensitive adhesive tape 10 having a tacky layer provided on one surface of a substrate film 1 composed of a polyolefin based resin composition comprising a polyolefin based resin and a white inorganic additive, an outer film layer 3 composed of a ethylene/ethyl acrylate based resin which is crosslinked by activated energy rays in the pressure of a crosslinking auxiliary is provided on the outer surface of the substrate film 1. The white inorganic additive comprises an inorganic compound such as magnesium hydroxide to be added as a flame-retardant or an inorganic compound such as calcium carbonate to be added as a filler. The crosslinking auxiliary is, e.g. adenosine phosphate. The activated energy rays are, e.g. electron rays, ultraviolet rays, alpha rays, or gamma rays.</p> |
