Use of FT-NIR Spectroscopy for Fast Quality Analysis of PET Packaging Material(PPT)

摘要

1. Polyethylene terephtalate (PET) containers are commonly made by using injection molding to manufacture preforms, which in turn are processed in high-speed stretch-blow molding machines. 2. Between insertion and extraction the stretch-blow molding process is run in multiple cavities in parallel, yielding quasi continuous production of containers at rates currently ranging up to 81,000 per houron a single stretch-blow molding machine.
