Plastics are almost everywhere to be seen and used for a lot of things and applications. Their uses are nearly endless and a plain plastic tray is just one of them. You probably have plenty of plastics that you use every day in your bakery but do you know what they are or how they are made? In simple scientific terms, plastics are a group of materials called polymers which refers to a substance made out of many parts or units that have been repeatedly replicated. A perfect illustration would be a chain of paper clips or a garland of paper strips.
In addition, it would be meaningful to know that plastics are not all synthetics. There are some naturally-occurring polymers such as cellulose and latex derived from tree sap. Most synthetic plastic materials are used to make plastic bags, plastic cups, bottles, pipes, and more. Plastics also come in various kinds, depending on how they are polymerized. For instance, a hardened silicone, a kind of synthetic polymer, is usually used to make plastic tray because of its resiliency and excellent resistance to heat. Other polymers like polyethylene, polystyrene and acrylics are thermoplastic in nature, meaning they also are made once heated and hardened once cooled.
Another great property of plastics is the fact that they can be easily reprocessed or recycled. Most countries have been recycling plastic tray, plastic packages, plastic bottles, and other plastic containers that significantly contributed to reducing carbon footprints. The plastics industry is one of the fastest-growing industries in the whole of the U.S. and across the world, producing tons of polymers every year. Fortunately, with the improved durability and longevity of synthetic polymers, the use of every piece of plastic material lasts for long years. This makes it a cost-effective material for a wide variety of applications.
