The ACI AMUT extrusion system is capable of producing high quality PET sheet from FDA and EFSA certified post-consumer PET flakes. The AMUT-EREMA system, including a decontamination/dehumidification process (approximately 1 hour), completely removes the volatile contaminants remaining in the flakes, producing perfect and unbreakable PET sheets without reducing the viscosity (IV) of PET more than any other system, and can produce PET sheets as thin as 1.5 mm thick.
