Multi-layer Polyethylene-Based Stretch-Shrinkable Film and Method for Manufacturing the Same (POLYTHYLENE TYPE STRETCHABLE / SHRINKABLE MULITILAYER FILM AND PREPARATION THEREOF)

摘要

The present invention provides a multilayer film having an inner layer and an outermost layer mainly composed of an intermediate layer composed mainly of a mixture of two specific linear low density polyethylenes, a specific high pressure polyethylene, an ethylene-α-olein copolymer, and a mixed composition of linear low density polyethylene. According to the present invention, it has an automatic packaging machine aptitude that is excellent in non-thermal heat sealability without cutting ability, transverse stretchability and deterioration in film lubricity and blocking defects, and especially stretch packaging used for prepackaging of food products mainly for retail products. Or as a film for shrink wrapping. In addition, in the multilayer film, the multilayer film obtained by blending at least two or more specific surfactant compositions has excellent anti-fog effect (initial anti-vibration property and anti-vibration persistence) against various packages in addition to these properties.
