Blends of polyethylene and polybutene and films made from the blends

A polymer blend consists of (a) 90.0-98.0 wt.% of polyethylene or copolymers of ethylene with 1.0-9.0 wt.% vinyl acetate having a melt index of 0.3-7.0g/10 mins. and a density of 917-933 kg/m3 and (b) 10.0-2.0 wt.% of polybutene of m.wt. 1000-2000, esp. 1300 or 700-1000, esp. 900. Films of the blend...

Zusammenfassung:A polymer blend consists of (a) 90.0-98.0 wt.% of polyethylene or copolymers of ethylene with 1.0-9.0 wt.% vinyl acetate having a melt index of 0.3-7.0g/10 mins. and a density of 917-933 kg/m3 and (b) 10.0-2.0 wt.% of polybutene of m.wt. 1000-2000, esp. 1300 or 700-1000, esp. 900. Films of the blend are also claimed. The films have excellent cling and tack props. making them suitable for use in self-sealing stretch wrapping and self sealing packaging and providing interlayer adhesion between layers of film.
