Frequently asked questions
GF grades require higher injection pressures. Strongly anisotropic shrinkage (perpendicular to fibres > along axis). Increased nozzle and mould wear — nitrided steels recommended. Drying identical to base grade.
PET (code 1) is the most widely recycled plastic in the world. Well-established recycling processes enable the production of food-grade r-PET for bottles, textile fibres and engineering components. The target is 90% collection in the EU by 2029.
PET is the standard for food packaging (FDA, EFSA, EU Regulation 10/2011). Approved for all types of food, including carbonated drinks, oils, and acidic foods. Recycled r-PET can be certified food-grade after approved decontamination.
