Packing peanuts are small, lightweight loose-fill cushioning materials used to protect fragile items during shipping. They come in three main types: traditional Styrofoam (polystyrene), anti-static pink Styrofoam for electronics, and biodegradable cornstarch peanuts. Each type protects packages differently and suits different products. Sold in bulk by the cubic foot, packing peanuts fill the void around items in a shipping box to prevent damage from movement and impact.
