A process for preparing an RPET polymer blend component comprises providing
a quantity of RPET flakes, comminuting the RPET flakes to prepare RPET
particles having an average mean particle size from about 500 microns to
about 5 microns, adding at least one specialty additive to the RPET
particles, and mixing the RPET particles and specialty additive, to
prepare a homogeneous blend of RPET carrier and specialty additive.
