After all, the quality of the end product must be good. An ideal possibility to combine low investment costs with an extended processing window for recycled material is offered by Gneuss Kunststofftechnik GmbH from Bad Oeynhausen, Germany with a special retrofit service. One of the companies that has used this service is Cotnyl S.A. from San Martín, thus being the first company in Ar- gentina to obtain local approval to produce packaging made of 100% r-PET.

On the other hand, plastic packaging in particular has fallen into disrepute and has received new, often negative attention from the public. The call for waste reduction and reasonable recycling of plastic packaging is becoming ever louder. The Eu- ropean Union has drawn up legal directives which stip- ulate that by December 31, 2025 50% of plastic pack- aging placed on the market in an EU member state must be recycled. “The demand for PET packaging sheet, which contains a high proportion of recycled material or is even made of 100% of it, has recently increased enormously due to public discussion and legal requirements.” PET Sheet Lines – Fit for Recycled Material Thanks to Retrofitted Line Components Key components and know-how for plant optimisation in sheet extrusion Gneuss Processing Unit withMRS Extruder and RSFgenius Filtration System at Cotnyl S.A. in Argentina
