Demand for food is growing rapidly. According to the Federal Ministry of Food and Agriculture, agricultural yields must be increased by up to two thirds over the next 30 years in order to meet global demand. Food is a valuable commodity. Nevertheless, the United Nations estimates that 1.3 billion tons of food are thrown away every year. Modern plastics already protect seeds in the field and help to improve crop yields. As packaging, they keep food such as, cheese and meat fresh for longer – and also improve food safety.
