Answer:
Polythene is commonly used as a packaging material. The most common polyethylene types used in food packaging are high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE).
Step-by-step explanation:
One of the most popular materials used in the food industry for packaging is petroleum plastics (synthetic polymers). Such polymers include polyethylene terephthalate (PET), low and high-density polyethylene (LDPE and HDPE respectively), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS). Paper, paperboard, and cardboard cartons are frequently used as packaging for products in stores as well as used in shipping. Corrugated cardboard, for example, has excellent structural stability for shipping, storing, and even marketing products.
