When standard-size stock cartons are used, the selected carton may not closely match the actual dimensions of the products inside. This can result in excessive empty space, greater use of void-fill materials, and increased parcel volume.
Manual processes also depend heavily on operator experience. During peak periods, or when handling a high variety of SKUs and multi-item orders, the risk of inconsistent packaging, shipping-label mismatches, and item omissions or mix-ups can increase.
