Appl. No.:

12/074114

Inventors:

David Cron - Ho-Ho-Kus NJ, US

David Rudd - South Hackensack NJ, US

International Classification:

B29C 67/00

US Classification:

264342 R, 425383

Abstract:

The present invention relates to a method and system for edge treatment of a film in which one or both edges of the film is heated to a temperature above a softening point of a DSC onset temperature. In one embodiment, the edges of film are heated to a temperature above the peak DSC temperature. A central portion of the film between the edges remains at a lower temperature. In one embodiment, an edge heat treatment apparatus having a heated channel is used to receive an edge portion of the film and heat the edge portion.

US Classification:

428516

Abstract:

The invention provides a stretch wrapping film (i. e. , non-heat shrinkable) having (i) skin layers and (ii) at least one core layer which includes at least 25% by weight, more preferably from about 60% to about 90% by weight (of the layer composition) of a propylene polymer, preferably a propylene homopolymer; for the film as a whole, the propylene content ranges from about 10% to about 65% by weight (of the film). In more preferred embodiments, the films include skin layers, intermediate layers, and a core layer. At least one of the intermediate and core layers contains the propylene polymer, which is preferably a homopolymer or a blend of homopolymer with linear low density polyethylene (LLDPE); the skin layers comprise an ethylene polymer, preferably a tacky LLDPE composition. These films have improved strength and tear and puncture resistance, and are especially suited for industrial wrapping of loaded pallets and other large objects such as furniture. These films are especially advantageous in providing a high holding force.
