Claims
- 1. A transparent plastic film having balanced physical properties comprising (1) a homopolymer of ethylene having a density of between about 0.92 to about 0.94 and a melt index of between about 1 decigrams per minute to about 6 decigrams per minute, said film having a two percent secant modulus of greater than 172 MPa and less than 210 MPa; and a Puncture, Propagation, and Tear resistance of greater than 140 mN/.mu.m and less than 200 mN/.mu.m;
- wherein the film has an amorphous phase and a crystalline phase with polyethylene crystalline units, said polyethylene crystalline units having an a-axis orientation, as measured by IR trichroism, of A.sub.X /A.sub.O between about 1.0 to 1.5; A.sub.Y /A.sub.O between about 0.7 to 1.0; and A.sub.Z /A.sub.O between about 0.7 to 1.0.
- 2. The film of claim 1 further comprising a cling additive in an amount of between about 0.2 to about 2.0 weight percent.
- 3. The film of claim 1 further comprising an antioxidant in an amount of between 200 to about 800 parts per million based on the weight of the ethylene.
- 4. The film of claim 1, wherein the homopolymer of ethylene is low density polyethylene.
