Biaxially oriented polyolefin multilayer film, manufacturing method of this biaxially oriented polyolefin multilayer film, multilayer film and packaging.

Abstract

The invention relates to bidirectional polyolefin multilayer films, a method for producing such bidirectional polyolefin multilayer films, multilayer films, and packaging. Bidirectional polyolefin films, comprising: (A) glycerin fatty acid esters composed of esters between fatty acids with 12 to 24 carbon atoms and glycerin; and (B) one or more substances selected from a group comprising fatty diethanolamines, fatty acid esters of polyoxyethylene fatty amines, fatty acid diethanolamides, and fatty acid monoesters of fatty acid diethanolamides, wherein the fatty acid glycerin ester (A) contains 0 to 15% by mass of fatty acid monoester glycerin, 30 to 60% by mass of fatty acid diester glycerin, 30 to 60% by mass of fatty acid diester glycerin, and fatty acid triesters glycerin, provided that the total amount of monoester, diester, and triester is 100% by mass.
