Abstract
A process for preparing a PET flake mixture for use in connection with the fabrication of high-performance plastic strapping comprises the steps of initially collecting post-consumer and non-post-consumer PET materials having an initially wide range of relatively low intrinsic viscosity (IV) values with a relatively low average intrinsic viscosity (IV) value and processing the same through solid state polymerization (SSP) so as to obtain a wide range of relatively high intrinsic viscosity (IV) values with a relatively high average intrinsic viscosity (IV) value. The initially collected materials are chopped into flakes and chunks and the chunks are flattened so as to render the remaining mixture comprised substantially entirely of flake materials or segments. This is advantageous because the flake segments, as opposed to the chunk segments, are able to be substantially increased in intrinsic viscosity (IV) values and within a relatively short period of time. The initially collected materials have intrinsic viscosity (IV) values which are within the range of 0.60 - 0.80 dl/g and as high as 0.90 dl/g and the diversity of such materials is underscored or emphasized by the fact that the difference in such intrinsic viscosity (IV) values of the initial or starting materials is at least, or greater than, 0.05 dl/g, is probably at least 0.10 dl/g and can be within the range of 0.10 - 0.30 dl/g.
