Title:

MULTILAYER STRETCHABLE AND SHRINKABLE POLYETHYLENE FILM AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/1996/009166

Kind Code:

A1

Abstract:

A multilayer film having the intermadiate layer mainly comprising a mixture of two specified linear low-density polyethylenes and the innermost and outermost layer each mainly comprising a mixture of specified high-pressure polyethylene, ethylene-'alpha'-olefin copolymer and linear low-density polyethylene. The film is free from such defects as blocking and reduction in foldability, transverse stretchability and slipperiness, has such an excellent low-temperature heat-sealability as to be adaptable to automatic packaging machines, and is particularly suitable as a stretch or shrink packaging film or use as a prepackage for retail goods represented by food. When a specified surfactant composition is added to at least two layers of the multilayer film, the resultant film has an excellent antifogging effect (initial antifogging effect and persistence thereof) on various substrates in addition to the abovementioned properties.
