| abstract |
A composition includes greater than 50 % by weight such as between 51 % and 99 % by weight, of a first PVdC copolymer having a weight average molecular weight of between 80,000 and 125,000, and less than 50 % by weight, such as between 1 % and 49 %, by weight of a second PVdC copolymer having a weight average molecular weight of between 126,000 and 180,000, the weight percent of each of the first and second polymers based on the combined weight of the first and second polymers. A film includes at least one layer having the above composition. A film can have at least one layer including a blend of a first vinylidene chloride polymer and a second vinylidene chloride polymer, the film having a free shrink ratio of between 0.6 and 2.2 at a shrink temperature of 180 °F., or a free shrink ratio of between 0.8 and 1.4 at a shrink temperature of 200 °F. Methods of making the film of the invention are also disclosed. |
