Packaging foam is a lightweight material used to protect fragile items during shipping and storage. It comes in various forms, such as sheets, rolls, and molded shapes, designed to cushion products and prevent damage from impacts. Commonly made from materials like polyethylene or polyurethane, packaging foam is often used in boxes, crates, and pallets. This type of foam is popular in industries like electronics, glass, and furniture, where delicate items need extra protection. Its ability to absorb shock and resist moisture makes it an effective choice for ensuring that products arrive safely at their destination.
