Injection Stretch Blow Moulding
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.
Packed with Sustainability
PET is one of the most easily recyclable materials for brands seeking Post Consumer Recycled (PCR) solutions. Requiring less energy to produce than glass, PET can also be made using bioplastics, such as sugarcane-based materials which uses ethanol from plant-based materials instead of fossil-based materials such as oil or gas.
Need an Environmental Solution?
The Truly Environmental Alternative To Glass
Because plastics are flexible and boast lower melting points, PET bottles require less energy to manufacture than glass. Up to 85% lighter than other packaging materials, PET helps cut transportation costs and reduce CO2 emissions. Recent figures indicate that nearly 60% of PET plastic bottles in the household waste stream are now collected for recycling
What are the benefits of the Injection Stretch Blow Moulding Process?
Polyethylene Terephthalate (PET) produces a clarity similar to glass
PET offers excellent barrier characteristics against carbon dioxide and oxygen
PET bottles require less energy to produce than glass bottles and are easily recycled
Bottles made from PET have a higher breakage resistance to avoid risk and injury
PET bottles are more durable and lightweight than glass bottles
Because PET is lighter than glass, it is more cost-effective to transport
