Weight loss for yogurt packaging

Schwälbchen AG, a dairy company in Bad Schwalbach, Germany, is now using beverage bottles made of BASF’s Polystyrene.

Serial production has started, after the switch from PET to PS was successfully tested on the existing filling equipment in a joint project.

The material is a highly impact-resistant polystyrene (PS-I) made by BASF that is used for injection blow molding and injection stretch blow molding.

The density of polystyrene would mean that the production of bottles would need about 20% less plastic.

This also translates into 20% less packaging material that has to be disposed of.

Polystyrene, which up to now has been known primarily as a material for food-product films and yogurt cups, is also proving its worth for re-sealable packaging made of plastic.
