**When were plastic bags manufactured?**.

Plastic bags were first manufactured in the early 1950s as a convenient alternative to paper bags. The production of plastic bags rapidly increased due to their durability and low cost, leading to their widespread popularity in retail stores and supermarkets.

**Step 1: Invention of plastic bags**.

In 1950, Swedish engineer Sten Gustaf Thulin invented the modern plastic bag. Thulin's design used a flat tube of plastic that was sealed at the bottom, creating a simple and efficient way to package products.

The first plastic bags were introduced to the market in the early 1950s, initially as sandwich bags and storage bags. Customers quickly recognized the convenience of using plastic bags for storage and transportation.

**Step 3: Adoption by retail stores and supermarkets**.

Retail stores and supermarkets began to adopt plastic bags in the mid-1950s due to their cost-effectiveness and ease of use. Plastic bags were seen as a more sanitary option compared to paper bags, which were prone to tearing and getting dirty.

**Step 4: Rapid increase in plastic bag production**.

By the late 1950s, plastic bag production had increased significantly as manufacturers recognized the demand for this convenient packaging solution. Plastic bags became a staple in the retail industry, used for carrying groceries, clothing, and other goods.

**Step 5: Environmental concerns and regulations**.

In recent years, plastic bags have come under scrutiny due to their negative impact on the environment. Many countries have implemented regulations to reduce the use of plastic bags and encourage the use of reusable bags instead.

In conclusion, plastic bags were first manufactured in the early 1950s and quickly gained popularity due to their convenience and affordability. Despite their widespread use, plastic bags have become a symbol of environmental pollution, leading to efforts to reduce their production and encourage sustainable alternatives.
