Our customer who is one of the primary packaging materials suppliers in China approved our 1000kg/hr BOPET extrusion system.
This system contains two sets of SAT40 twin screw extruders and something group of SAT110 twin screw extruder that constituted a multi-layers BOPET extrusion system. This client also bought one set of SAT95 twin screw extruder for film margin recycle collection from us.
Comparing with traditional sole screw extruder process, twin screw extruder course of action for BOPET may save power energy up to 35%. This improvement substantially cut the processing price through the elimination of electric power and time-consuming pre-crystallization and pre-drying program. In addition, it conserve labor cost and turnover time of pre-handling recycleables.
The secret of the cutting edge is the fact that twin screw extruder can outfit with high vacuum system which exposure your pet melt in the vacuum condition as long as possible to be able to exhaust out the moisture and low molecular particles that may entail PET hydrolysis so plastic compounding machines the IV of PET will drop down. Solitary screw extruder is normally impossible to equip with strong vacuum program without lack of output.
