Flow Packs for Sustainable Packaging.

Why Sustainability is important in Packaging

Sustainable food packaging is a crucial aspect of the food industry. It aims to reduce the environmental impact of packaging materials while preserving the quality and safety of food products. Packaging plays a vital role in protecting food from physical, chemical, and biological hazards. It extends shelf life and also enhances consumer appeal. Conventional packaging materials, such as plastics, metals, and paper, pose significant challenges for the environment. They consume large amounts of resources, generate waste, and contribute to greenhouse gas emissions. In 2021, the EU generated 188.7 kg packaging waste per inhabitant, 10.8 kg more per person than in 2020, the biggest increase in 10 years. There is a growing need for sustainable packaging solutions that can minimize  negative effects and promote a circular economy.
