Shavings and chips are made out of polystyrene to fill any casing and their function is to deaden shocks in order that the content is kept safe. Minced polystyrene is obtained from the rejects of virgin material for blending concrete to get lighter building substructures. It’s a cheap lightweight filling material that gives protection, ensuring a high coefficient of cushioning. The Poliplast polystyrene chips protect your products from bumps occupying all the empty spaces between objects, ensuring the integrity of your item during any stage of the delivery. Each bag contains M3 1⁄4.
