Packaging films are thin layers of material used to wrap and protect products. They are commonly made from plastics like polyethylene or polypropylene, which provide durability and flexibility. These films help keep items fresh, prevent contamination, and make them easier to handle and transport. In addition to food products, packaging films are also used for pharmaceuticals, cosmetics, and various consumer goods. They can be designed to be transparent for visibility or printed with colorful designs for branding. The use of packaging films plays a crucial role in reducing waste and improving product shelf life.
