Plastic containers made of high-density polyethylene (HDPE), polyethylene terephthalate (PET), and polypropylene (PP) are widely used in the food packaging industry. HDPE is a strong and durable material that is resistant to impact, chemicals, and moisture, making it ideal for packaging products such as milk, juice, and yogurt. PET is a lightweight and transparent material that is commonly used for packaging beverages, condiments, and snacks. PP is a versatile plastic that can be molded into various shapes and sizes and is often used for packaging products such as sauces, soups, and ready-to-eat meals.
