1. A packaging film for food application comprising a composition comprising:

(A) from 86 wt % to 91 wt % of a vinylidene chloride/methyl acrylate interpolymer having from 7.7 wt % to 8.5 wt % methyl acrylate mer units in the interpolymer;

(B) from 7 wt % to 10 wt % of an epoxy plasticizer that is epoxidized soybean oil based on total weight of the composition; and

(C) from 2 wt % to less than 4 wt % of an acrylate polymer based on total weight of the composition, the acrylate polymer consisting of an interpolymer of methyl methacrylate, butyl methacrylate, and butyl acrylate; wherein

(D) the composition has a crystallization time greater than 50 minutes to crystallization at 35° C. measured with a differential scanning calorimeter; and
