Abstract
A pressure sensitive adhesive tape for skin, including a stretchable base material having good moisture permeability and a pressure sensitive adhesive layer formed on at least one side of the base material, wherein the adhesive tape has features that (a) the conformability to a stretchable film is at most 4.2 times as much as the stress of the stretchable film at 15% elongation, (b) the water-vapor transmission rate is at least 500 g/m,·24 h, and (c) the adhesive strength to bakelite is at most 1.5 N/15 mm, and a base material of a pressure sensitive adhesive tape for skin, including a microporous film formed from a resin composition containing a polyolefin resin and an inorganic filler, and having features that (1) the thickness is 40 to 200 &mgr;m, (2) the average pore size is 0.02 to 10 &mgr;m, (3) the air permeability is 10 to 400 sec/100 cc, (4) the water-vapor transmission rate is 1,000 to 20,000 g/m,·24 h, and (5) the stresses at 15% elongation in the machine direction and transverse direction is both 0.5 to 15 N/15 mm.
