Lightweight, stable, and resource-efficient: In just four months, KHS and Husky Technologies have jointly developed one of the world’s lightest PET bottles for still beverages. The 5.89-gram “Factor 101” bottle sets new standards in material savings, top-load stability, and line compatibility.

By developing one of the lightest PET bottles for still beverages, KHS is pushing the boundaries of lightweight packaging technology. Under the working title of Factor 101, in close cooperation with Canadian-based injection moulding technology equipment and services provider Husky Technologies, a container has been produced that uses just 5.89 grams of material to hold 591 milliliters of product. This is equivalent to the 20-ounce size common in the United States.

At Drinktec 2017 KHS presented its Factor 100 concept as a feasibility study that featured a PET bottle weighing approximately five grams with a capacity of 500 milliliters. A number of optimizations have now been made to the further development, as KHS packaging designer Fabian Osterhold in Hamburg explains. “With such extreme lightweighting, what’s known as the top load is especially important. This value tells us how sturdy the bottle is from a vertical perspective. It determines whether the container can be stacked or not and survive transportation undamaged.”
