<p>A non-yellowing pressure-sensitive adhesive tape with a polyolefin film layer and a fibrous web layer. A propylene film layer has an antioxidant package of: (i) 0.004 to 0.04 weight percent of IrganoxTM 1010: (ii) 0.03 to 0.2 weight percent of a solid phosphite antioxidant; (iii) 0.05 to 0.4 weight percent of a thioester; and (iv) 0.05 to 0.4 weight percent of an inorganic acid scavenger. The tackified synthetic rubber pressure-sensitive adhesive layer comprises 100 parts of a polystyrene-polydiene block copolymer, and 20 to 300 parts of a compatible tackifying agent and an antioxidant package, based on 100 parts on the polystyrene-polydiene block copolymer, comprising: (i) 0.1 to 0.6 parts IrganoxTM 1010; (ii) 0.1 to 0.6 parts IrganoxTM 565; (iii) 0.0 to 0.6 parts of a phosphite antioxidant.</p> |
