Plastic bags have become a staple of modern life, but their popularity is a relatively recent phenomenon. Before the 1980s, paper bags were the primary method of carrying groceries. The first generation of plastic bags was introduced in the US in the 1950s, but these were produce bags, trash bags, and garment bags. The modern lightweight shopping bag was invented in the early 1960s by Swedish engineer Sten Gustaf Thulin for the packaging company Celloplast. The bags were patented in 1965 and began to replace cloth and paper bags in Europe. By the late 1970s, plastic bags had entered the US market, and by the end of 1985, 75% of US grocery stores carried them. So, while the technology to create plastic bags may have existed in 1918, they were not in widespread use at that time.

What You'll Learn
Plastic bags were not popular in 1918
Plastic bags were introduced as an alternative to paper bags in the early 1970s, but they were initially met with skepticism by both retailers and consumers. It wasn't until the benefits of plastic bags, such as durability and cost-effectiveness, became apparent that they began to gain traction. By the 1980s, large supermarket chains in the United States, such as Safeway and Kroger, started switching to plastic bags, leading to their widespread adoption. This marked a significant shift in retail and solidified the plastic bag's place in American consumer culture.
The late 20th century saw a period of innovation in the plastic bag industry, with companies designing bags with handles cut from a single tube of plastic film and introducing biodegradable alternatives. However, the discussion around the environmental impact of single-use plastic bags also gained momentum during this time. As the negative effects of plastic pollution became more widely known, many countries began to implement bans and restrictions on plastic bags, with Bangladesh being one of the first to do so in 2002.
In summary, plastic bags were not popular in 1918, and it took several decades for them to become a common item. The history of plastic bags is a story of innovation, convenience, and, ultimately, a growing awareness of their environmental impact, leading to a global movement to reduce and replace single-use plastics.

Polyethylene, the most common plastic, was created in 1933
Plastic bags have become an omnipresent product found in every corner of the world. They are produced at a rate of up to one trillion bags per year and are intensifying some major environmental challenges.
The history of the plastic bag is a story of innovation and persuasion. In the 1970s, plastic bags were a novelty, and by the 1980s, they had become a lucrative market for the plastics industry. The switch from paper bags to plastic bags was driven by cost and convenience, with single-use plastic bags being cheaper and more widely available.
The creation of polyethylene, the most common plastic, played a significant role in the popularity of plastic bags. Polyethylene was first created in 1933 by accident at a chemical plant in Northwich, England, by Eric Fawcett and Reginald Gibson, who were chemists at Imperial Chemical Industries (ICI). During their experiments with ethylene gas, a test vessel leaked, leaving trace amounts of oxygen in their ethylene samples. The oxygen reacted with the ethylene to create a new substance with long –CH2– chains, now known as polyethylene.
While polyethylene had been created in small batches before, this was the first synthesis that was industrially practical. Recognizing its potential, the British military utilized polyethylene during World War II for insulating radar cabling.
The widespread usage of polyethylene has had a significant impact on waste management due to its non-biodegradable nature. Polyethylene is chemically resilient, making it challenging to decompose when disposed of improperly. However, polyethylene is also a versatile material used in various products, from shopping bags and Tupperware to artificial hip and knee joints.
The invention of polyethylene has revolutionized the modern world, but it has also contributed to the growing environmental concerns associated with plastic pollution.

Plastic bags were introduced in the 1950s
Plastic bags were not available in 1918. The plastic shopping bag was introduced in the 1950s, marking the beginning of a global shift from paper bags to plastic bags.
Polyethylene, the most commonly used plastic, was first created in 1898, but it was not until the mid-1950s that a high-density polyethylene was invented, enabling the production of cheap yet strong plastic bags. This new material was a breakthrough for the plastic bag industry, as it gave plastics the strength needed to be both light and mouldable while remaining robust.
In the early 1950s, American and European patent applications related to the production of plastic shopping bags began to emerge. These patents referred to composite constructions with handles fixed to the bag in a secondary manufacturing process. However, it was not until the late 1950s that the Swedish company Aktiebolaget Celloplast developed the first carrier bag with handles die-cut from a single, continuous tube of plastic film. This design was a significant innovation, and the company held a virtual monopoly on the plastic bag market for over a decade.
The plastic bag quickly began to replace cloth and paper bags in Europe. By the 1970s, plastic shopping bags had become a novelty, and they soon spread to the United States and other countries worldwide. Plastic companies aggressively marketed their single-use products as superior to reusable bags, and by the end of the 1980s, plastic bags had almost entirely replaced paper bags globally.
The widespread adoption of plastic bags can be attributed to their convenience, low cost, and strength compared to paper bags. However, the environmental ramifications of their widespread use have been disastrous, contributing to global warming and massive ocean pollution.

Plastic bags became popular in the 1970s
Plastic bags did not exist in 1918. In fact, it wasn't until several decades later, in 1933, that polyethylene, the most commonly used plastic today, was created by accident at a chemical plant in Northwich, England.
However, in the 1970s, plastic shopping bags became a novelty. By the late 1970s, plastic bags had become popular in grocery stores, with a few shops offering them to customers. This was despite the fact that plastic bags had been regarded as a novelty just a decade earlier.
So, what changed?
Firstly, the development of plastic bags can be attributed to the work of several companies in the 1950s and 1960s. In the 1950s, a Swedish company, Aktiebolaget Celloplast, developed the carrier bag with handles die-cut from a single, continuous tube of plastic film. This design was produced across Europe and eventually in the United States through Celloplast USA.
Then, in 1965, Celloplast obtained a U.S. patent for a bag with an open top to insert items and handles for convenient carrying. This design, later called the "T-shirt plastic bag", became the model for every plastic bag used in grocery stores.
Another factor that contributed to the popularity of plastic bags was their cost-effectiveness. Plastic bags were significantly cheaper for stores to purchase than paper bags, which could cost up to four times as much. For example, in 1985, it was recorded that one thousand plastic bags cost $24, while the same number of paper bags cost $30. As a result, businesses were drawn to using plastic bags, despite initial customer preferences for paper bags.
By the mid-1980s, 75% of supermarkets were offering plastic bags to their customers, and by the end of the decade, plastic bags had almost entirely replaced paper bags worldwide.
However, the popularity of plastic bags has come at a cost. Being lightweight and aerodynamic, they can easily escape from garbage and recycling trucks, littering streets, communities, and waterways. They also pose a serious threat to marine life, with animals mistaking them for food and ingesting them. As a result, by the early 2000s, governments worldwide began placing restrictions on plastic bags to address their environmental impact.

Plastic bags were patented in 1965
Plastic bags did not exist in 1918. In fact, plastic bags only came into existence in the 1950s, and even then, they were not yet popular. The commonly used plastic, polyethylene, was first created in 1933 by accident at a chemical plant in Northwich, England.
The modern lightweight plastic bag is the invention of Swedish engineer Sten Gustaf Thulin, who, in the early 1960s, developed a method of creating a simple one-piece bag by folding, welding, and die-cutting a flat tube of plastic for the packaging company Celloplast of Norrköping, Sweden. Thulin's design was lightweight yet durable, with a high load-carrying capacity. The bags were also cheap to produce, making them highly attractive to retailers.
In 1965, Thulin's design was patented worldwide by Celloplast. By the 1970s, plastic bags were a novelty, and companies began to aggressively market their single-use products as superior to paper and reusable bags. By the 1980s, plastic bags had become common, and they started to replace paper bags. Two of the biggest supermarket chains in the United States, Safeway and Kroger, switched to plastic bags in 1982.
The widespread use of plastic bags has led to some major environmental challenges. Plastic bags are now found everywhere, from the depths of the oceans to Mount Everest and the polar ice caps. They are extremely durable, taking between 500 and 1,000 years to decompose, and are one of the most prevalent types of litter in inhabited areas. Due to their low weight and resistance to degradation, plastic bags have contributed to the proliferation of plastic waste in the environment. As a result, many countries have introduced legislation to restrict the use of plastic bags and encourage the use of sustainable alternatives.
