Plastic is a huge industry comprising of many players. Here, we’ll take a look at who they are and what services or products they provide.
When asked to describe the plastic industry, most people tend to focus first on the “plastics product manufacturers”. Let’s start with these manufacturers and we’ll radiate out to see who else work with these manufacturers before a product is finally produced and delivered to the consumers. plastic rotomolding companies
There are 2 ways to describe what a manufacturer does – either by process (the plastics making methods they use), or by the industry that they are serving (packaging, automotive, etc.). The final product to be made determines the type of processes to be used. It is not necessary that a manufacturer be equipped with all known processes. Most manufacturers are specialized in only one or two methods. Bigger plants may have 3 or 4 but it is rarely possible to have every process under one roof since the selection of process is dependent on the final product and industry that a manufacturer is supplying to. Eg, a company that supplies to the electronic industry may have injection molding process to make TV casing and other components. Blow molding processes that are used to make bottles are of little use to them.
Plastics are used extensively by different industries. These industries includes: medical and pharmaceutical; packaging; electronic and electrical; automotive; toys; building and construction; home products; agriculture; and many more. While most manufacturers sell their plastic parts and products to others industries, some trade among themselves. Eg. Plastic bags manufacturers who specialize on producing bags will sell them to other plastics manufacturers for packaging purposes.
There are many types of plastics materials. Within each type of plastic materials, are different grades – suited for different products and for different types of processes. Eg. PP (polypropylene) is a common material and has many applications. However, PP materials that are used for making plastic bags are different from those that are used to make car bumpers – although they may come from the same material suppliers who are also known as Resin Producers.
Resin Producers are petrol-chemical plants that produce plastic resins – the raw material for making plastics. Here, they convert by-products from crude oil refineries to make plastic materials. Different resin producers specialize in different types of materials. They supply large quantities to manufacturers (those who consume a few hundred tons of the same material monthly) and to Resin Traders.
Resin Traders buy the raw material from resin producers and sell to manufacturers in smaller quantities. A trader will often represent several resin producers thus providing manufacturers with a large selection of different materials.
