Premium hand wrap multi-layer film products

摘要

The present invention provides improved multi-layer hand wrap stretch film products. The products comprise at least five layers. The first and second outer layers each represent from 10 to 25 percent by weight of the film and comprise a blend of a linear low density polyethylene, and a metallocenes based linear low density polyethylene. The film includes a first and second inner layer where each represents from 20 to 40 percent by weight of the film and comprises a blend of linear low density polyethylene and a low density polyethylene. The core layer represents from 10 to 30 percent by weight of the film and comprises linear low density polyethylene. The linear low density polyethylene components are either single products or blends of products. The final film exhibits improved properties needed in hand wrap films such as puncture resistance and load retention. Polyisobutylenes are optionally added to at least one of the outer layer in an amount sufficient to enhance the cling force of the applicable outer layer.
