Packing is placing the product inside a protective container; packaging is the whole protective arrangement: product pack, carton, filler, pallet, stretch wrap, strapping and label. Each layer answers a different risk: impact, moisture, crushing, shifting, theft or mix-ups.
The cost of packaging is not just the price of the material. Heavy or bulky packaging raises freight and increases volumetric weight in air transport; weak packaging means damage, compensation claims and lost customers. To find the right balance, the value of the product, the mode of transport and the number of transfers on the journey have to be considered together.
