Packaging film is a thin layer of material used to wrap and protect products for storage and transportation. It is commonly made from materials like polyethylene or polypropylene, which provide durability and flexibility. Packaging film helps keep items fresh, prevents damage, and can be used for various products, including food, electronics, and household goods. This type of film can be produced in different forms, such as shrink wrap, stretch film, or vacuum bags, depending on the specific needs of the product. Additionally, packaging film can be printed with branding or information, making it an essential component in the packaging industry.
