'''* Flexibility with input material'''

Depending on the end application the system processes PET bottle flakes, ground amorphous skeleton waste/edge trim and virgin material (also in mixtures), i.e. bulk densities of 250 to ~~850 kg~~/m³.

rPET pellets which not only fulfil but exceed all current minimum requirements with regard to direct food contact for PET packaging solutions: that is the end product in bottle-to-bottle recycling with VACUREMA Prime ~~technology. This high-end~~ PET extrusion system features two crystallisation dryers operating in batch mode. ~~A compact, space-saving all-in-one solution which achieves IV increases and a remarkable cleaning effect. As the user you are flexible at all times and can react~~ quickly to current market requirements: whether it‘s decontaminated, pre-dried and crystallised rPET flakes or high-quality, melt-filtered rPET pellets – products produced using ~~VACUREMA~~ Prime technology fulfil the respective criteria of the FDA, EFSA and many major brand owners. If IV values of > 0.9 dl/g or very high throughputs (> 2500 kg/h) are required, ~~EREMA~~ can offer ~~VACUREMA~~ technology also in combination with an SSP solution from Polymetrix.
