Injection Stretch Blow Moulding

Centred at the Robinson Madrox site in Poland, the addition of injection stretch blow moulding (ISBM) technology was largely prompted by growing customer demand for lightweight, glass clear containers.

This process also guarantees consistently accurate neck finish profiles. The majority of Robinson's packaging made in this way is in the form of screw-threaded bottles, but they can also produce preforms for conversion by customers.

Robinson offers both single-stage and two-stage options, predominantly using PET material but also PP where appropriate.

The key advantages of ISBM are:

  • Flexibility to make smaller runs
  • Preform wall thickness can be varied to allow blowing of rectangular and non-round shapes
  • Good O2 and CO2 barrier properties for PET bottles
  • Reduced weight containers
  • Dimensionally accurate neck finishes
  • High breakage resistance
