A step-by-step guide to the Injection Stretch Blow Moulding Process

Injection Stretch Blowmoulding (ISB) enables the manufacture of high-quality bottles in PET (Polyethylene Terephthalate), which boast a clarity similar to glass. However, the ISB process can also produce less clear materials, such as polypropylene (PP) if required.

Spectra’s state-of-the-art injection stretch blow-moulding machines can produce PET containers in capacity sizes from 50ml up to 500ml. Available in a virtually limitless choice of colours, our PET bottles can be provided in solid opaque finishes as well as varying stylish translucent shades.
