The composition comprises a polymer emulsion containing, for example, polyvinylidene chloride having a particle size distribution finer than 10µ, and an additive with generally the same size distribution, for example aluminum silicate, 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.
La composition comprend une émulsion d'un polymère contenant, par exemple, du chlorure de polyvinylidène ayant une granulométrie inférieure à 10 µ et un additif ayant sensiblement la même granulométrie tel qu'un silicate d'aluminium, un carbonate de calcium, un polyvinylacétate, un polystyrène, des polyacrylates, en émulsion ou sous forme de poudre, cet additif étant capable d'une combinaison interstitielle avec les particules de polymère. La composition a un pH critique entre environ 2 et environ 7. On décrit également un procédé pour transformer en pâte à papier un emballage portant le revêtement.
