TWIST WRAPPING FILM THAT IS PREPARED FROM BIAXIALLY-ORIENTED POLYPROPYLENE AND CAN BE METALLIZED

摘要

PURPOSE: To provide a transparent biaxially stretched multilayered film having excellent adhesion characteristics for especially depositing a metal on at least its single surface and equipped with good twist characteristics. CONSTITUTION: A multilayered polypropylene film is characterized by that (a) a base layer pref. contains a low molecular-wt. hydrocarbon resin having a softening point of 130-180 deg.C in a ratio of 5-30% in addition to polypropylene, (b) a base layer contains 0.05-0.1% of antistatic agent, (c) an outside layer contains 0.1-0.5% of a sticking (blocking) preventing agent but contains no lubricant at all and (d) the film is oriented isotropically.
