BOPET extrusion program continues to be accepted successfully
Our customer who's one of the biggest packaging material suppliers in China accepted 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 consumer also bought one group of SAT95 twin screw extruder for film margin recycle line from us.
Comparing with traditional sole screw extruder practice, twin screw extruder approach for BOPET can save electricity energy as much as 35%. This improvement substantially cut the processing cost through the elimination of electricity 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 the cutting edge is the fact that twin screw extruder can outfit with high extruder dies 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 that the IV of PET will drop down. One screw extruder is usually impossible to equip with strong vacuum system without loss of output.
