Injection stretch blow molding (ISBM) is a conversion process of thermoplastic resins used to produce bottles and containers  for beverages and household cleaning products. 

Key stages of the process include: the injection molding of preforms, their transfer to blowing equipment, heating, stretching, blowing and cooling of the final container shape.  This process allows  good dimensional stability control and minimum production waste.

LyondellBasell offers its Stretchene range for this process as well as Moplen, Pro-fax, Alathon, and Petrothene grades.
