Cast films

摘要

"Cast" films having excellent puncture resistance and tear strength are manufactured from "pseudohomogeneous" linear low-density polyethylene resin. The preferred pseudohomogeneous resins used in the present invention are prepared with an advanced Ziegler Natta catalyst (having a magnesium component and a titanium component), preferably in medium pressure solution polymerization process. The films of this invention are especially suitable for "pallet wrapping" and for wrapping goods of unusual or uneven shapes and sizes.
