Better protection against stress cracking
- Under the rigorous International Society of Beverage Technologists (ISBT) stress-cracking test protocol, the StarLite CSD base lasted 30% longer for 0.5 litre bottles, 50% longer for 1.5 litre bottles and 60% longer for 2.0 litre bottles.
Better base resistance
- The base successfully completed the ISBT 24-hour creeping test under 45°C conditions, compared with 38°C required under standard testing. This means the base is less likely to burst during production, or deform during transport, which can unbalance pallets.
- Base weight can be reduced by up to 20% for 0.5 litre bottles (from 5 grams average base weight to 4 grams), 19% for 1.5 litre (from 9 grams to 7.3 grams), and 17% for 2 litres (from 12 to 10 grams). This can lead to cost savings of up to EUR 331,000 per year for 0.5 litre lines, EUR 563,000 per year for 1.5 litre lines and EUR 662,000 per year for 2 litre lines, based on Sidel data.*
Reduced energy use
- Under controlled conditions the base can be blown using down to 16 bars of air pressure versus 25 bars average for 0.5 litre bottles, 18 bars versus 26 bars average for 1.5 litre bottles, and 20 bars versus 28-30 bars average for 2 litre bottles, creating up to EUR 78,700 cost savings per year, based on Sidel data.**
