Our customer who's one of the primary packaging materials suppliers in China accepted our 1000kg/hr BOPET extrusion system.
This system contains 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 set of SAT95 twin screw extruder for film margin recycle series from us.
Evaluating with traditional sole screw extruder course of action, twin screw extruder process for BOPET can save electricity energy up to 35%. This improvement substantially slice the developing cost by eliminating time-consuming and electricity pre-crystallization and pre-drying system. It save labor price and turnover double screw extruder period of pre-handling raw materials 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 exhaust out the moisture and low molecular particles that will entail PET hydrolysis so that the IV of PET will drop down. One screw extruder is definitely difficult to equip with solid vacuum system without loss of output.
