Packing peanuts, also referred to as loose fill, are small, lightweight, peanut shaped packing foam that are designed to interlock when compressed and flow freely when loose.
The interlocking shape allows packing peanut to cushion the products being shipped. As such, packing peanuts are used to fill up empty spaces around products being shipped. Packing peanuts cannot keep products in place when they are shipped, and so they should not be used with products that can shift and move in transit. The packing peanuts can generate static electricity so they should not be used when shipping electronic equipment.P
