Cartons affect the full sequence of warehousing operations, but are frequently overlooked.
Besides carton sizes, you must also consider carton construction. One box out of square may not matter much; over a whole shipment, un-squared cartons can cause issues up and down the line. They don’t stack well, may not convey correctly and could result in product damage. In fact, you may pay higher shipping costs due to the size, composition and condition of the simplest thing: the carton.
