ABSTRACT:
The composition comprises a polymer emulsion containing, for example, polyvinylidene chloride having a particle size distribution finer than 10.mu., and an additive with generally the same size distribution, for example aluminum silicte, calcium carbonate, polyvinyl acetate polystyrene, polyacrylates, in emulsion or powder form which is capable of interstitial combination with the polymer particles. The composition has a critical pH between about 2 and 7. The method of repulping coated packaging is also disclosed.
