The Rise of Plastic Plastic began to be mass-produced after the Second World War and then again during the 1960’s and 1970’s when consumers craved plastics to replace traditional materials because they are cheap, versatile, sanitary, and easy to manufacture into a variety of forms.
Why did we start using plastic?
Plastics Come of Age The need to preserve scarce natural resources made the production of synthetic alternatives a priority. Plastics provided those substitutes. Nylon, invented by Wallace Carothers in 1935 as a synthetic silk, was used during the war for parachutes, ropes, body armor, helmet liners, and more.
