Plastics enable development of lightweight and less bulky protective packaging and typically account for just 1 - 3% of a product's weight. The average plastic packs now weigh up to eighty percent less than they did twenty years ago. 100 kgs of plastic components replace parts that once weighed up to 300 kgs. A car weighing one ton and combining 70 kgs of plastics uses 4% less fuel and produces lower emissions.
