Abstract
A low shrink tension packaging film contains a first polymer that is an ethylene-unsaturated carboxylic acid copolymer and a second polymer containing one or more copolymers selected from an ethylene-vinyl acetate copolymer and an ethylene-acrylate copolymer. A molar ratio of a specific structural unit of the first polymer to a specific structural unit of the second polymer is in a specific range, such that the low shrink tension packaging film has excellent optical and mechanical properties and a significantly low tension applied when being shrunk by heat.
