ANN ARBOR, MICH. — Amcor Rigid Plastics says it has created the lightest 64-ounce hot-fill PET container of its kind, weighing only 59 grams.
The company developed Powerblock 3.0 technology to make the bottle, which comes with a 38mm finish, 13.2 percent lighter than the typical 68-gram bottle.
"The Powerblock 3.0 container is a major breakthrough because we achieved a highly sustainable packaging solution without compromising performance," Michael Lane, Amcor engineer, said in a statement. "Our unique lightweight design retained line/stack handling performance and maintained ergonomic features for consumer handling."
Advantages of the Powerblock technology include optimized footprint (width and depth) for improved pallet pattern and corrugate savings. The bottles are also easy for the consumer to handle, says Amcor.
The firm is currently only using the technology for 64oz hot-fill containers but says it will adapt it to other bottles in the future. The stock bottle is currently commercially available in the US.
The Valox iQ recycled resins, which are based on PBT incorporating post-consumer PET feedstock, can be used for cosmetics, particularly airless covers, it adds.
