German-based component specialist Kreyenborg has reportedly found that recycled polyethylene terephthalate, (r-PET), taken from crushed plastic bottles is effective and efficient for the production of PET flat films. In addition, the company has found that the production of flat films on extrusion lines is highly productive.
Kreyenborg claims that filtration technology ensures the required product quality even at high R-PET raw material usage. The company provides modular discharge units consisting of melt pumps and screen changers. This allows for the high demands of film extrusion on the homogeneous melt quality and pressure constancy in the process.
