plastics include synthetic or semi-synthetic polymerization products. Plastics are formed from organic condensation or the addition of polymers and can also contain other substances to improve the quality of the plastic. There are several natural polymers including plastics. Plastics can be formed into films or synthetic fibers
Plastic materials can be formed according to what is needed when exposed to heat and pressure. The shape itself varies from bars, blocks, to cylinders. All these basic forms can then be reprocessed into crackers, food wrappers, bottle packaging, and so on.
