"Plastics" derived their name from their properties to be molded, cast, extruded or processed into a variety of forms, including solid objects, films and filaments. These properties arise from their molecular structure. Plastics are polymers, very long chain molecules that consist of subunits (monomers) linked together by chemical bonds. The monomers of petrochemical plastics are inorganic materials (such as styrene) and are not biodegradable.
Plastic has many properties which has made it a raw material of choice for Manufactures of plastic Bags and packing materials. Cost of production, light weight, strength, easy process of manufacture, and availability are few of the properties. There is nothing wrong with plastic as a material. Man has simply not put the plastic to the right use/ or using it without taking proper care of other related norms of usage.
PLASTIC AS PACKING MATERIAL
Plastic has replaced the traditional material ( paper/cloth etc) as packing and carry bags because of cost and convenience which is possibly a wrong choice of material for such use. Even though plastic bags can preserve food and can be used for growing vegetables in a controlled environment, their method of disposal has creates unprecedented pollution problem.
Plastic has many more uses other than Plastic Bags and Packing material. It is used for manufacturing of protective covers and parts for many machines, which should be the preferred utility for plastic.
