Plastic Bags Everywhere
A Bag That Is Light and Strong
Plastic shopping bags are very thin. A lightweight bag uses only a small amount of material, but it can still be strong enough to carry groceries, clothes, or other purchases.
These bags can fold almost flat, weigh very little, and resist water. That makes large numbers of them easy for stores to keep and move.
A lightweight plastic shopping bag can have walls less than 50 microns thick. That is about half the thickness of a sheet of printer paper.
Even though the plastic is so thin, the bag can still do its job. This mix of low weight and strength helped plastic bags become common.
Easy for Stores and Shoppers
The single-use plastic grocery bag was patented in 1965.
Its design fit easily into the way many stores worked. A retailer is a business that sells products directly to shoppers. Retailers could keep large numbers of thin plastic bags near checkout areas without needing much storage space.
Plastic bags also offered convenience, meaning they made shopping quicker or easier. A shopper did not need to bring a container from home. The store could simply provide a bag for carrying purchases.
Plastic bags became common because they worked well for both stores and shoppers.
Used Once, Carried Everywhere
Many shopping bags are single-use. This means they are mainly designed for one short period of use before they are thrown away.
A bag may carry purchases for only a few minutes or hours, although some people use their bags again.
One bag may seem like a tiny amount of plastic. The scale changes when the same kind of bag is used again and again around the world.
People around the world use about 5 trillion plastic bags each year. That averages about 160,000 bags every second.
Even a very light object can create a huge amount of material when people use trillions of them.
Why One Small Item Became a Big Issue
The same qualities that made plastic bags useful also caused problems after use. Thin bags are easy to hand out in large numbers. Their light weight also means discarded bags can be carried away by wind.
Lightweight plastic shopping bags became very common litter in Europe. The European Union has been working to reduce this problem since 2015.
One way countries tried to reduce bag use was by stopping stores from giving them away for free. In many places, shoppers began paying for bags instead. This also encouraged some people to bring reusable bags.
Plastic bags did not spread for only one reason. Their strength, low weight, low cost, and convenience all worked together. The story of the plastic bag shows how one small item can become a much bigger issue when it fits easily into everyday systems.
