EcoBlend vPET/rPET blend for food grade applications
The POLYMETRIX EcoBlendTM rPET technology is used to produce premixed PET pellets consisting of virgin and recycled PET. After the CP process, the rPET melt flow from an on-site extrusion system is mixed with the virgin PET melt. Alternatively vPET pellets can be blended with rPET pellets directly after pelletizing. A blend of rPET and vPET is conveyed to the SSP and treated simultaneously.
As a result the output from the SSP consists of the CP plant capacity plus the added rPET capacity. The proportion of rPET in the material can be up to 25%. The EcoBlendTM technology is suitable for installation in a new plant or as an expansion into an existing PET manufacturing plant. For an expansion project the CP plant remains unchanged. The SSP plant is upgraded for the new material composition and the increase in overall capacity.
