2.5% lightweighting for preforms

| Preform developements | SIPA | Vittorio Veneto

SIPA has recently successfully developed a new PET preform geometry that yields a product 2.5% lighter than before. This is a major achievement, both in terms of sustainability and economic advantage to the customer.

The preform has an optimized base design that is noticeably less angular than competing designs on the market while achieve the same weight reduction. It is a result of SIPA’s extensive expertise in preform and bottle design as well as in injection and blowing processes.

GIVING THE CUSTOMER AN EDGE, HELPING THE ENVIRONMENT

SIPA has recently successfully developed a new PET preform geometry that yields a product 2.5% lighter than before. This is a major achievement, both in terms of sustainability and economic advantage to the customer.

The preform has an optimized base design that is noticeably less angular than competing designs on the market while achieve the same weight reduction. It is a result of SIPA’s extensive expertise in preform and bottle design as well as in injection and blowing processes.

The weight reduction has been achieved without any loss in mechanical performance of the blown bottle. Visual appearance is actually improved, because there is less residual material in the area of the preform injection point. This achievement has been verified in an application at one of our Chinese customers’ plants, where blowing tests produced very good performance results.
