Abstract
PURPOSE: A protective tape, surely peeling off from an adherend without change of property or deformation of the adherend by heating, which comprises, as a base material, a heat-shrinkable film having a specified range of absolute value of difference in heat-shrinkage initiating temperatures between longitudinal and crosswise directions.
CONSTITUTION: In a protective tape comprising, as a base material, a heat- shrinkable film having longitudinal and crosswise heat shrinkage each of 15% or higher, preferably, 18% or more and 35% or more at 120°C, respectively, the absolute value of difference in heat shrinkage initiating temperatures between longitudinal and crosswise directions ranges from 20 to 50°C, preferably from 30 to 40°C. The protective tape surely peels off from an adherend without change of property or deformation of the adherend by heating. A polyolefin polymer is excellent as the material of the protective tape. Said protective tape completely or almost completely peels off without evolution of any toxic gas at a low temperature.
