Plasticzer in alkyl acrylate vinylidene chloride polymer

An article selected from a package, a container, a laminate, a sausage casing or a combination thereof comprising a monolayer blown film prepared from a composition including at least one vinylidene chloride polymer and at least one plasticizer present in an amount of from 3 to 9 parts by weight per hundred parts of polymer, and selected from ester plasticizers and combinations of ester plasticizer and epoxy plasticizer wherein at least one vinylidene chloride polymer comprises vinylidene chloride and at least one alkyl acrylate selected from methyl acrylate, ethyl acrylate, or butyl acrylate or a combination thereof in an amount of from 3.8 to 7.5 mole percent of the monomer content of the vinylidene chloride polymer from wherein the alkyl acrylate is present in an amount that results in at least 4 of the following characteristics:

• (a) the crystallization temperature as determined by differential scanning calorimetry (DSC) is at most about 75° C.;
• (b) the remelt temperature as determined by DSC is from 100° C. to 175° C.;
• (c) the failure rate is at most about 150 per 10000 after having been heated to a temperature of from 75° C. to 145° C. for a period of from 20 minutes to 200 minutes:
• (d) the oxygen permeability as determined by the procedures of ASTM D3985 is from 4.6×10E-17 m3.m/m2.sec.atm to 4.6×10E-13 m3.m/m2.sec.atm;
• and
• (e) the glass transition temperature as determined by DSC of at most about 0° C.
