When Were Bags Invented & Who Invented Them?

With mentions throughout the documented history of all civilizations, it's impossible to know who invented bags.

However, the invention of burlap bags can be traced to 1793 India, where fibers from the native jute plant were woven together to create burlap fabric. And until the mid-19th century, this is how bags were made – by hand, using natural materials.

When Were Paper Bags Invented?

Mass-produced paper bags were invented in 1852, with one major drawback – they didn't have bottoms. At this point, you're probably wondering: Is a bag without a bottom…a bag?

"Large, not terribly useful paper envelopes" more accurately describes the output of this new machine, but no matter – it was a 19th-century disruption. A machine-made, disposable carrier unlike anything seen before? It's no surprise their inventor was able to call them whatever he liked.

Paper Bag History Develops With New Additions

In 1912, a St. Paul, Minnesota grocer invented a reinforced, handled shopping bag after seeing his customers struggle to carry brown grocery bags. On behalf of all shoppers everywhere, thank you, Walter Deubener.

This part of paper bag history is as enduring as the square-bottom bag. The best modern grocery bag designs include reinforced seams and handles or straps to carry more, farther.

Paper or Plastic? Bag History Takes a Turn

America's plastic bag history started in 1979, and by the 1990s, plastic bags had taken over the world.

The obvious advantage for retailers was that they were much cheaper than paper bags. Shoppers preferred them because durable and weather-resistant plastic proved relatively easier to carry.

What We Know Now About Our History of Bag Choices

The Swedish engineer who invented the one-piece, high-density polyethylene grocery bag in 1965 thought it was better for the environment because it was reusable and saved trees. However, plastic bags are so cheap to make and easy to use that they have become a single-use product due to convenience, with serious environmental consequences.

The original breast milk cooler includes a clear pocket for a name and date card. Plus, you get your pick of fun styles like polka dots.

Eight states have banned single-use plastic bags, and some of the nation's largest retailers, like Walmart and Kroger, are planning a nationwide ban or pilot-testing bagless stores. Similar efforts have been made all over the world.

Although the history of bags has a dark side, today's policymakers and consumers are wiser to the realities of plastic pollution, and many people are choosing alternatives for getting their purchases home. The demand has created new styles of grocery bags that are better than ever, and transporting fresh food has never been easier.

Reusable but Cooler Grocery Bag Design

The 90s saw what a plastic bag habit can do to a planet, and the modern reusable tote was born.

Over the years, improved materials like insulation have been incorporated into reusable grocery bag designs. Perishable foods can go without refrigeration for one to two hours, and insulation helps make the most of that time – but only by adding ice or ice packs can you keep foods safe for longer than two hours.

PackIt is the bag that's an ice pack, with the features of a traditional reusable tote plus the functionality of a cooler. None of the many different types of grocery bags, with or without insulation, have PackIt's built-in cooling capabilities.
