Abstract

PURPOSE: To offer the polyolefin film inscribed on the face, useful as a wrapping sheet, having a specified heat contraction coefficient and excellent in creases-proof property, transparency, brightness, moisture-proof property, strength, etc..
CONSTITUTION: By controlling the temperature of heat treatment or the like after elongation, for instance, the heat contraction coefficient of a polyolefin (preferably biaxially orientated) film is 0.3 (preferably 0.4) or more along both of longitudinal and transversal directions at 50°C and 10% or less along both of the longitudinal and transversal directions at 120°C.
