1、Designation:D267314Standard Specification forOriented Polypropylene Film1This standard is issued under the fixed designation D2673;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indi
2、cates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers oriented polypropylene(OPP)film in the thickness range from 10 to 75 m(0.4 to 3.0 mils).1.2 The film can contain colorants,stabilizers,or
3、otheradditives,and can be coated for the improvement of perfor-mance properties(heat sealability,gas permeability,and soforth).1.3 The film can be annealed(heat-set)to reduce theunrestrained linear shrinkage and shrink tension on exposure toheat.1.4 The values stated in SI units are to be regarded a
