In many cases small objects are typically grouped together in one package for reasons of efficiency. Stationery for example is often all kept in one piece of cardboard packaging. Similarly, any liquids, powders, and granular materials need containment in order to avoid contamination. It is for these reasons that packaging manufacturers are necessary for both containment and agglomeration purposes.
If we look at various packaging labels, we can see that they are a necessity for information transmission during the shipping and transaction process. Packages and labels such as that used in foam packaging communicate how to use, transport, recycle, or dispose of the package or product. As is the case with pharmaceuticals, food, medical, and chemical products, many of these pieces of information are required by governments. Labelling the correct ways to dispose of packaging and products can bring environmental benefits as well as improving productivity. Some packages and labels are also used for track and trace purposes.
