A history of the plastic Shopping Bag
Plastic shopping bags are now an omnipresent global product, produced at a rate of one trillion a year.
How did this happen?
1933 – Polyethylene, the most commonly used plastic, is created by accident at a chemical plant in Northwich, England. While polyethylene had been created in small batches before, this was the first synthesis of the material that was industrially practical, and it was initially used in secret by the British military during World War II.
1965 – The one-piece polyethylene shopping bag is patented by the Swedish company Celloplast. Designed by engineer Sten Gustaf Thulin, the plastic bag quickly begins to replace cloth and plastic in Europe.
1979 – Already controlling 80% of the bag market in Europe, plastic bags go abroad and are widely introduced to the United States. Plastic companies begin to aggressively market their product as superior to paper and reusable bags
1982 – Safeway and Kroger, two of the biggest supermarket chains in the United States, switch to plastic bags. More stores follow suit and by the end of the decade plastic bags will have almost replaced paper around the world.
1997 – Sailor and researcher Charles Moore discovers the Great Pacific Garbage Patch, the largest of several gyres in the world’s oceans where immense amounts of plastic waste have accumulated, threatening marine life. Plastic bags are notorious for killing sea turtles, which mistakenly think they are jellyfish and eat them.
2002 – Bangladesh is the first country in the world to implement a ban on thin plastic bags, after it was found they played a key role in clogging drainage systems during disastrous flooding. Other countries begin to follow suit.
