BOPET extrusion program successfully has been recognized


Our customer who's one of the biggest packaging materials suppliers in China approved our 1000kg/hr BOPET extrusion system.

This system consisted of 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.

Evaluating with traditional sole screw extruder process, twin screw extruder process for BOPET can save power energy up to 35%. This improvement substantially cut the processing cost through the elimination of electric power and time-consuming pre-crystallization and pre-drying program. It save labor price and turnover period of pre-handling raw materials also.

The secret of this cutting edge is that twin screw extruder can outfit with high vacuum system which exposure the PET melt in the vacuum extrusion screw condition so long as possible in order to exhaust out the moisture and low molecular particles that may entail PET hydrolysis so the IV of PET will drop down. Single screw extruder is certainly impossible to equip with solid vacuum program without loss of output.
