Abstract

L'invention concerne un procédé industriel pour préparer un matériau d'emballage alimentaire entièrement biodégradable. Le procédé selon l'invention utilise de la proline et un polymère d'éthylène-alcool vinylique respectivement en tant que plastifiant et agent de compatibilité, et comprend les étapes suivantes : tout d'abord, de l'amidon de maïs, de l'amidon de pomme de terre, de l'amidon de blé et de l'amidon de manioc sont ultra-micronisés par granulation physique afin d'améliorer la fluidité et la capacité de remplissage, puis une certaine quantité de proline, de polymère d'éthylène-alcool vinylique et d'amines couramment utilisées dans les procédés classiques, en tant qu'agent de réticulation, sont ajoutés pour modifier l'amidon. L'amidon modifié est extrudé par extrusion bivis à mécanosynthèse et laminage pour produire des panneaux. Des procédés de moulage sous vide et/ou de moulage par compression, entre autres, sont alors employés pour fabriquer les matériaux d'emballage à base d'amidon. Le matériau d'emballage alimentaire fabriqué par ce procédé peut être entièrement biodégradé et est conforme à la norme nationale chinoise relative à l'hygiène alimentaire, tout en conservant de bonnes propriétés mécaniques. Grâce à son caractère écologique, son efficacité énergétique, son faible coût et sa simplicité, l'ensemble du procédé peut être mis en œuvre à l'échelle industrielle.
