Düsseldorf, Germany — KHS Corpoplast GmbH developed the first juice bottle made from recycled PET thanks to a glass lining that protects sensitive beverages and then washes away at material recovery facilities.
The Dortmund, Germany-based manufacturer of filling and packaging systems showed its concept bottle called Beyond Juice for the first time at K 2019 in Düsseldorf, Oct. 16-23.
The container uses KHS' FreshSafePET barrier technology. Launched last year, the barrier puts an ultrathin, water-soluble glass coating on the inside of the bottle that washes off during the recycling process.
KHS took its FreshSafePET and added other eco-friendly features for its Beyond Juice concept, Philipp Langhammer, a product manager of barrier technology at KHS, told Plastics News. He pointed to a small recyclable polypropylene label that wraps around the neck of the bottle and adhesive glue dots that can hold six packs of beverages together.
The glue eliminates secondary packaging, such as plastic rings and film wraps. Like the glass coating, which KHS branded as Plasmax, the glue is soluble at 60-80° C and washes away during recycling.
"This package combines all the sustainable technologies that KHS offers," Langhammer said. "The design has a small label so the bottle can be recognized as PET during the sorting and recycling process. If you have a sleeve, it could be recognized as a PP or PE [polyethylene] bottle."
