What are the common materials used in food packaging?
Food packaging materials vary widely and include plastics, metals, glass, and paper. Plastics such as polyethylene, polypropylene, and polyvinyl chloride are frequently used due to their versatility and cost-effectiveness. Metals, including aluminum and tin, are often used for cans, while glass is popular for jars and bottles due to its inert nature. Paper and cardboard are used for dry goods and have the advantage of being biodegradable.
