19 Sep 2019 --- Concern about the potential health implications of microplastics in food and drinks is rising, and for a good reason. A study published by the Norwegian University of Science and Technology (NTNU) estimates that more than 4,000 chemicals are used in modern-day plastic packaging production. However, with over 5,000 different types of plastic puzzled together to create plastic packaging, the number of chemicals used for production will increase further, the research suggests. It is, therefore, becoming increasingly difficult to ensure safety standards.
