This diagram shows the various stages in which raw material is converted to plastic products. The product example described here is a common shampoo bottle made of PE material.

From the beginning, the natural raw material of crude oil is converted into a monomer substance called Ethylene. From here the monomer goes through a polymerization process which incorporates other additives to form a polymer which produce what is known as plastics resins. Plastics manufacturers purchase these resins and through the use of various plastics processing machines – injection molding, blow molding, etc., to manufacture a product. The product – in this case – a shampoo goes through other secondary processes like filling the content (shampoo), applying labels, assembly of caps, etc., before it is shipped to a retailer.
