Conventional packing materials come in different types and serve various roles in packaging, such as primary, secondary, and tertiary functions. Their primary function encompasses the initial layer, safeguarding individual products from potential damage. In turn, the secondary function of packing materials is to transport goods contained within primary packages. At the same time, their tertiary function is to facilitate the shipment of products enclosed in secondary packaging, commonly in warehouses. Here are the different types of packing materials and their respective functions.
