The kind of container utilized for shipping products at the early stage of history was not given much thought compared to the sales of these products themselves. Unlike today when it is easy to buy packaging supplies of high quality, processors until end of 19th century had the tendency of applying easy-access materials to transport their goods to the market.
Materials Used in Early Containers
Containers were mostly made using cork, clay and wood at these times. A shift however came about in the 20th century in the materials utilized for shipment of food. The larger number of those made got constructed from glass, paper and even metals. Another evolution that took place as a relatively new material, Polyethylene Terephthalate or PETE, entered the marketplace. Invention of the versatile plastic prompted food processors to begin using it for packing and shipping the majority of food items they produced and distributed to their consumers. This arose because Polyethylene, being an extremely versatile plastic could be molded or stamped into numerous shapes. As well, producing it also became quite a costly exercise. Increase in environmental awareness also moved consumers to start clamoring for more eco-friendly solutions of containment from suppliers. This occurred since it became notable that a majority of plastics were manufactured using petroleum products and like non-renewable resources. The clamor for newer options that were friendlier to the environment heated up, resulting in the rapid evolution of packaging supplies within the food industry.
Information Displayed on Containers
Packaging has not just evolved as a method of storage and preservation only, but an aid for information and communications to the end-user. All containers of food contain detailed information concerning the quantities and contents of the diverse foodstuff-components they carry. Such information could include listing of all components within food by chemical name, along with the physical or chemical properties relative to their projected use. Another type of information available includes caloric content and percentage of minerals along with basic nutritional building blocks such as fat and proteins. Today, manufacturers of various products can for example buy packaging supplies and get them customized with targeted information their consumers.
Eco-Friendly Packaging Materials
The use and development of safe and green products in construction of packages is yet another major tend in packaging observable today. Development of this new form of material utilized in constructing containers directly corresponds to the demands posed by consumers for an eco-friendlier footprint by manufacturers globally. Development of natural fibers of cellulose that can be recycled or composted after usage is yet another example of this instance. In addition, natural fiber containers have a host of other gains, primarily because they decompose in presence of moisture, heat and oxygen. As well, microorganisms get to consumer them by nature as part of their regular diet. Mundane substances like these as well can be formed readily into any imaginable shape. It follows that all of these configurations of container-cans can be crafted from such biodegradable substances.
New technology is playing an instrumental role to the end-consumer as well as manufacturers who always need to buy packaging supplies for food products.
