Circular FoodPack aims to enable the circular use of plastic packaging, addressing the most sensitive product category: food. The main function of food packaging is the protection of the product during transport from manufacturer to consumer and maximize the food shelf life, thus reducing food waste and its carbon footprint. Therefore, food packaging has to fulfil high requirements, like being light-weight, impermeable, sufficiently tear-resistant and printable, with an appealing haptic and not release chemicals into the food in quantities that are harmful to human health.
