Rather than disposing of unused cardboard, which can become very costly, the PacMate offers an alternative. By shredding this spare cardboard, the PacMate creates a shock-absorbent padding perfect for stuffing in packages or boxes. Shipping departments can use this packing material for transporting fragile or sensitive goods. Working with one layer of cardboard at a time, the PacMate breaks down your material into a 1/8″ x 4 1/2″ grid cut padding.
