Plastic food packaging is one of the most widely used forms of packaging for both fresh and processed foods. It offers an effective barrier against moisture, air, and contaminants, extending the shelf life of products. Common types of plastic used for food packaging include polyethylene, polypropylene, polystyrene, and polyethylene terephthalate (PET), each offering different properties for specific applications. For example, PET is commonly used for beverage bottles, while polyethylene is ideal for flexible packaging like bags and films. The lightweight and durable nature of plastic makes it highly cost-effective, and it can be molded into various shapes, such as bottles, jars, containers, and trays, depending on the food type. However, there is an increasing focus on reducing plastic waste through the development of biodegradable or recyclable plastics to mitigate environmental impact.
