Title:
HEAT-SHRINKABLE LAMINATED POLYETHYLENE FILM
Document Type and Number:
WIPO Patent Application WO/1995/012490
Kind Code:
A1
Abstract:
A heat-shrinkable laminated polyethylene film which is excellent in the adaptability for wrapping machines. The film is composed of an intermediate layer comprising a composition based on a linear low-density polyethylene (A) having a density of 0.910-0.930 g/cm3, a melt index of 0.1-0.8 g/10 min, a total heat quantity of fusion of 135 mJ/mg or above, and the endothermic area above the melting point accounting for at least 12 % of the total endothermic area, and the innermost and outermost layers each comprising a composition based on a linear low-density polyethylene (B) having a density of 0.910-0.930 g/cm3, a melt index of 0.8-5.0 g/10 min, a total heat quantity of fusion of 135-160 mJ/mg, and the endothermic area above the melting point accounting for at least 12 % of the total endothermic area.
