FLEXIBLE POLYOLEFIN FILM

摘要

PURPOSE:To obtain the title film showing little unevenness in thickness and an excellent peelability by preparing a biaxially oriented film comprising an olefin copolymer resin and having specified physical properties. CONSTITUTION:A biaxially oriented film comprising an olefin copolymer resin (e.g. a mixture of a butene-propylene copolymer with a low-density PE) and having a Young's modulus in at least one direction of 100kg/mm<2> or lower and a surface roughness on at least one surface of 0.03mum or higher is prepd.
