PURPOSE: To provide a polyvinyl chloride heat-shrinkable film not generating natural shrinkage caused by a change with the elapse of time and good in packing properties. CONSTITUTION: A vinyl chloride resin sheet is uniaxially stretched by 2.0 times or more to form a vinyl chloride resin heat-shrinkable film 15 which is, in turn, taken up to form a roll-shaped film l1 The vinyl chloride resin heat- shrinkable film 15 of which the heat shrinkability in the same direction is 0.5% or more at 50 deg.C is passed through the nips between rollers 2, 3, 4 held to 40-65 deg.C in surface temp. to be wound into a roll form. |
