| Cutomer’s Key problem by using Double-screw PET Sheet Extrusion line with vacuum degassing | |
|  | |
| 1 | Big problem with Vacuum system | 
| 2 | Final PET Sheet is brittleness | 
| 3 | Clarity of PET Sheet is bad | 
| 4 | Output is not stable | 
Normally the PET Bottle flakes or sheet scrap with initial moisture level of up to 8000-10000ppm. The PET Bottle flakes or sheet scrap (Virgin or mixed) will be recrystallized in Infrared crystal dryer in 10-15mins, the drying temperature will be 150-180℃ and dried to 150-300ppm,then fed to Double screw extruding system for further processing
>>Limiting the hydrolytic degradation of the viscosity
>>Prevent increasing AA levels for materials with food contact
>>Increasing the capacity of the production line up to 50%
>>Securing equal moisture levels for the extruder
>>More consistent performance of the vacuum degassing compared to non-dried material
>> Advanced quality of the end product —Equal and repeatable input moisture content of the material
