Our customer who's one of the biggest packaging materials suppliers in China accepted our 1000kg/hr BOPET extrusion system.
This system consisted of two sets of SAT40 twin screw extruders and one 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 collection from us.
Comparing with traditional sole screw extruder approach, twin screw extruder process for BOPET can save power energy up to 35%. This improvement substantially slice the developing cost through the elimination of time-consuming and electricity pre-crystallization and pre-drying system. It conserve labor price and turnover time of pre-handling recycleables also.
The secret of the cutting edge is the fact that twin screw extruder can outfit with high vacuum system which exposure the PET melt in the vacuum condition as long as possible to be able to mixer extruder exhaust out the moisture and low molecular particles that will entail PET hydrolysis so the IV of PET will drop down. One screw extruder can be impossible to equip with strong vacuum program without lack of output.
