PROBLEM TO BE SOLVED: To provide laminated tapes for packaging materials which excel in thermal adhesion to packaging base material such as carrier tapes and, simultaneously, exhibit high antistatic properties independently of high and low humidity or even after long-term storage. SOLUTION: The laminated tapes for packaging materials have an adhesive layer containing a base polymer, a tackifying resin layer, a polymeric antistatic agent, and a filler which has been laminated on a support base material. The adhesive layer may contain, based on 100 pts.wt. base polymer, 2-50 pts.wt. tackifying resin, 1-150 pts.wt. polymeric anti-static agent, and 5-100 pts.wt. filler. The adhesive layer has a thickness of, e.g. about 5-50μm, and a surface resistivity of, e.g. <=1013Ω/(square).
