Mitsubishi Heavy Industries Ltd. has found a way to enhance the sealing performance of plastic, allowing beer makers to reduce their need for aluminum cans and create new kinds of product containers.
Mitsubishi said the equipment coats the inner surface of a plastic bottle with a substance known as DLC, or "diamond-like carbon," which makes the bottle more than 10 times as resistant to oxygen penetration or carbon dioxide leakage.
