Most Technically Useful Material
Because of their high functionality, plastics are being used increasingly in the design of food packaging . Plastics are light, durable, strong, dent and shatter-proof and can be compressed, molded and sealed to prevent leakage. They have excellent insulating properties and transport easily.
Plastics are available in stretchable films as thin as a strand of hair or as rigid as steel or glass. In many cases, plastic packaging is reusable and highly recyclable. There are plastic films that can detect toxins, report on freshness, and provide a barrier to food-decaying gases. And because plastics are versatile, they can take an almost infinite variety of shapes which makes them the ideal packaging material.
