The end result is a PET bottle that offers improved bottle resistance, as well as better stability throughout the supply chain. The technology helps avoid material waste during production and storage and offers a great consumer experience, without compromising on the safety standards of the beverage. Sidel's packaging experts conducted various trails through computer simulations, followed by real-world physical tests, to achieve this optimum strength.
The Sidel StarLite Tropical base is already in production in far-eastern countries by Sidel customers who have trialled the base and achieved great performance results, including significant improvements to stress cracking.
Improved bottle resistance throughout the supply chain
The StarLite Tropical base, designed to improve resistance performance, has been evaluated and qualified under rigorous test protocols (1)
- Its optimised geometry reinforces all the zones which are more susceptible to stress cracking, due to mechanical constraints. This avoids potential breaking of the bottle walls and base, which can be caused by interactions with fluids or chemicals during conveying.
- When the bottle is under pressure at high temperature, it demonstrates good base roll-out resistance and it is less likely to burst during production or to deform during transportation.
