Provided is a process for preparing a PVDC additive blend in which an additive is blended with PVDC under high shear blending to produce a highly uniform blend in which the additive is homogeneously distributed throughout the PVDC. It has been found that performing high shear blending in multiple successive stages in which the concentration of the additive in the blend is reduced in each successive stage helps in prove the uniformity of the PVDC additive blend. For example, the high shear blending may be carried out in 2 to 6 stages, and in particular, from 2 to 4 stages. Also provided is a PVDC additive blend having a uniform blend of PVDC and an additive, such as a blend of a PVDC copolymer of vinylidene chloride and methyl acrylate and a fluorescing agent, such as 2,2(2,5-thiophenylendiyl)bis(5-tert-butylbenzoxazole).
