Abstract
Official abstract text for this publication.
A composition comprising an ethylene-based polymer, wherein the ethylene-based polymer comprises the following properties: a) an Mw(abs) from 130,000 to 162,000 g/mol; b) a melt index (I2) from 1.5 to 3.0 g/10 min; c) an ADF LS from 0.350 to 0.450 for molecular weight ≥500,000 g/mol.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising an ethylene-based polymer, wherein the ethylene-based polymer comprises the following properties: a) an Mw(abs) from 130,000 to 162,000 g/mol; b) a melt index (I2) from 1.5 to 3.0 g/10 min; and c) an ADF LS from 0.350 to 0.450 for molecular weight ≥500,000 g/mol. 2. The composition of claim 1 , wherein the ethylene-based polymer further comprises an ADF IR from 0.200 to 0.250 for molecular weight ≤15,000 g/mol. 3. The composition of claim 1 , wherein the ethylene-based polymer further comprises an ADF DV from 0.180 to 0.240 for molecular weight ≥200,000 g/mol. 4. The composition of claim 1 , wherein the ethylene-based polymer further comprises an ADF DV ≤0.210 for molecular weight ≥200,000 g/mol. 5. The composition of claim 1 , wherein the ethylene-based polymer has a density is from 0.923 to 0.927 g/cc (1 cc=1 cm 3 ). 6. The composition of claim 1 , wherein the ethylene-based polymer is an LDPE. 7. The composition of claim 1 , wherein the composition comprises a second ethylene-based polymer. 8. An article comprising at least one component formed from the composition of claim 1 . 9. A film comprising the composition of claim 1 , wherein the film has a 45° gloss >72% and a 2% MD secant modulus >30,000 psi for a 2.0±0.3 mil film thickness. 10. A film comprising the composition of claim 1 , wherein the film has a ratio of MD shrink tension to CD shrink tension of less than 7.0 and a CD shrink tension greater than 0.9, each for a 2.0±0.3 mil film thickness.
