ABSTRACT:
A process for manufacturing thermoplastic materials having an elevated gas impermeability and/or improved physical properties. This process is characterized in that it comprises mixing at least partially incompatible polymers, gelling them by the combined action of heat, pressure and kneading. The gelled mixture is then subjected to laminar flow through substantially parallel surfaces in which the ratio of the length of the surfaces to the distance between them is greater than 10.
A thermoplastic material having increased gas impermeability as well as containers made out of said materials.
A packaging method in which the thermoplastic materials of the invention are used to package oxygen sensitive materials.
