METHOD FOR RECYCLING OF PET, HETEROGEN PET FLAKES AND PLASTIC STRID

摘要

The present invention relates to a process for making PET material suitable for the production of high quality plastic tape, comprising the steps of: distributing a wide range of BV (internal viscosity) with a BV value of 0.60 dl / g to 0.80 dl. / g, but this value is up to 0.95 dl / gle; mixing the collected material and converting it into a heterogeneous mixture of BV, which is a heterogeneous mixture of substantially fluffy and debrisous pieces; and the heterogeneous mixture is subjected directly to solid state polymerization (SSP) to a heterogeneous material having an average BV of at least 0.90 dl / g. ŕ
