Packaging is usually used to contain, protect, handle or deliver goods like food or products in general. Besides the content, packaging also includes auxiliary or ancillary elements (such as labels, lids (on yogurt pots, for example), fillings, among others).
Packaging can be made from different types of material, such as glass, cardboard, plastic or metal, among others.
Paper is an organic material that is primarily made from the cellulose fibers of virgin wood from trees which is used to obtain pulp. This cellulose pulp can be obtained from virgin wood or also from recycled paper.
Glass is an inorganic material that is obtained mainly from silica sand (SiO2, around 70%), calcium carbonate (Ca2CO3, around 15%), limestone (CaCO3, approximately 10%) and other additives, by melting at about 1,500 ºC (2,732 ºF).
According to different sources, glass was first manufactured around the year 3500 a.C. in Egypt other sources indicate its origin to be2500 a.C. in Mesopotamia– as a decorative element, and its different uses have evolved. Thus, glass has been used to manufacture vessels, windows and nowadays, above all, for packaging, specifically for liquids, since it’s a type of packaging that neither interferes nor alters the taste of its contents. We have been manufacturing glass for the last 4,500 years, at least.
