Hand wrap multilayer 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 4 to 13 percent by weight of the film and each comprises a blend of two different linear low density polyethylene products. The film includes a first and second inner layer where each represents from 20 to 40 percent by weight of the film and comprises linear low density polyethylene products. The core layer represents from 10 to 30 percent by weight of the film and comprises linear low density polyethylene products. The final film exhibits improved properties needed in hand wrap films such as puncture resistance and load retention. Preferably, each of the outer layers comprises a blend of linear low density-polyethylene hexene/copolymers and linear low density-polyethylene/butene copolymers. The same linear low density-polyethylene/butene copolymer may be utilized in each of the layers. In one process, the first and second inner layers are drawn from an extruder at a faster rate than the core layer and the outer layers.
