Sidel Group said it beat the world record for lightweighting of hot-fillable PET bottles — less than 19 grams on a half-liter bottle — and did it with innovative shapes.
Sidel has introduced the Skyward and Curvy designs.
Skyward is a long silhouette with cylindrical and square shapes and just four panels. Curvy sports curves, spirals and a twisted back that is a support beam. The Curvy bottle does not have panels.
The new geometric structure of the body compensates for deformation during cooling.
Sidel said the bottles, which weigh just 18.9 grams each, can be blow molded at the rate of 1,800 bottles per hour, per mold, using standard Sidel equipment, thanks to heating optimization with the company's SBO Universal range of machines.
