One Stage Injection Stretch Blow Molding Machine


PET bottles are widely used in the beverage packing industry, mainly because PET is non-toxic and highly resistant to impact. Furthermore, PET looks crystalline and feels like glass, giving the container a better appearance than PVC, PE, or PP which have lower transparency. As a result, PET bottles and containers are playing the leading role in the container packing industry.
