History of Plastic Bags: How Did We Get Here

Why Are Single Use Plastic Bags Everywhere?

Plastic bags are ubiquitous and most people don’t question it. Why?

Less than 50 years ago plastic bags were a rarity. Now you it seems like you can’t buy anything without it being carried out in a branded plastic bag.

If we can understand how we got ourselves here, maybe we can find a way to get ourselves out.

Polyethylene (the most common type of plastic used for disposable bags) was first created in 1898 but it was not until the mid 1950s that a high-density polyethylene was invented. High density polyethylene was the “breakthrough” that enabled the production of cheap, yet strong plastic bags.

This seemingly simple invention changed the way we shop and had unimaginable consequences for our natural environment.

 

A Brief History of Disposable Bags

1933 - Polyethylene (the most common type of plastic used for disposable bags) is invented.

1953 – High-density polyethylene (HDPE) is invented, giving plastics the strength they need to be light, moldable, and still strong.

Quick Facts:

Karl Zeigler, one of the chemists who invented HDPE won a nobel prize for chemistry in 1965.
Plastic was a highly guarded secret when first invented as it was used by the US military during WWII as an insulating material which allowed them to place radar into airplanes for the first time.

 

1965 -  The plastic bag we use today is invented by the Swedish company Celloplast.

1980s – The Dixie Bag Company begins manufacturing and marketing plastic bags as an alternative to the then used paper bags in grocery stores.

1982 – Grocery chains Kroger and Safeway replace their paper bags with plastic.

After 1982 – It didn’t take long for grocers and department stores to realize that plastic bags were stronger and cheaper. 

Plastic’s Rise to Dominance

Disposable plastic bags became so popular so fast mainly because of their convenience.

Before plastic bags, there was paper. Paper bags worked but they were not easy to carry and they weren’t nearly as strong as plastic. The most important part… paper was more expensive to produce than plastic.

The plastic bag not only made life easier for the consumer, it also saved retailers money.

Although we see the downsides of plastic bags today, you can see why at the time they were adopted so rapidly.

The Problem We Didn’t See Coming (or Didn’t Care To See)

The problem with plastic that wasn’t considered at the time, is its impact on our environment and how that inevitably impacts us.

High-density polyethylene’s application to plastic bags may have benefited the consumer and the retailer, but the environmental ramifications of widespread use are disastrous.

There are a host of issues caused by plastic bags that directly impact humans. The main issues are:

  • Environmental – from its contribution to global warming to massive ocean pollution, plastic bags have become one of the largest environmental issues of our time.
  • Health – plastics are made of synthetic molecules that can have negative impacts on our health and ramifications of environmental degradation are also taking their toll on human health.
  • Cost – the cost of disposal and clean up of plastic bags comes back to the tax payer.

What Does This Mean for Us?

Plastic bags have risen to dominance because of the need for a cheap and useful way to transport goods. Unfortunately, we are now paying the price with environmental degradation and the health implications that result.

Although most of this transition was out of the hands of the consumer, our transition to a more sustainable future very much is.

Now that we understand the impact of our disposable bag use, it’s up to us to find and use alternatives.

The plastic bag revolution started with an invention and proliferated one bag at a time as consumers found it more useful. Now it’s time for a replacement. Here are a few options: alternatives to plastic bags.
