In the United Kingdom, Starbucks is testing fiber-based cold cups designed and produced by Finnish packaging specialist Huhtamaki.
According to Packaging World, the trial is being conducted across selected Starbucks stores in the U.K. The single-use cups are made from fiber-based materials and feature a compostable barrier coating, offering an alternative to the conventional plastic-lined paper cups commonly used in the food service industry. This trial aims to ensure the new material can maintain structural integrity and prevent leakage or condensation as well as existing solutions. The cups are also compostable under industrial conditions.
