Packaging resins are plastic materials used in the production of packaging solutions, offering durability, flexibility, and protection for various products. Common types include polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET), which are widely used in industries such as food and beverages, healthcare, and consumer goods. These resins provide moisture resistance, strength, and lightweight properties, making them essential for both rigid and flexible packaging applications.
