Have you ever stopped to think about a world without can liners?

If you were born in the 1960’s, you probably can’t remember a time without can liners, and just take for granted that we have always had them.

However, the can liner was invented for very important public health reasons and still serves the public well today.

The Invention of the Can Liner

A Canadian inventor named Harry Wasylyk Sr. is credited with inventing the plastic can liner in 1950, and along with Larry Hanson who worked for the Union Carbide Company, his invention was proliferated throughout the world.

Wasylyk was experimenting in his home with a new stretchy and waterproof material after World War II called polyethylene. He found that by taking polyethylene resin and heating it up and pressurizing them to make them more pliable, he could transform the polyethylene resin pellets into plastic bags through a process called extrusion.

The first facility to use this invention was the Winnipeg General Hospital, which was looking for ways to keep germ-infested waste away from patients, visitors, and workers. As healthcare workers continued to make the connection between germs and pathogens and illness and disease that could result from exposure, the plastic can liner was a helpful tool in protecting public health.

As a matter of fact, before the invention of the Polio vaccine, plastic can liners are credited with helping prevent the spread of Polio in hospitals.

As other hospitals heard about this invention, they also began to use can liners. Eventually, the Union Carbide Company bought out Wasylyk and Hansen and began marketing can liners to other businesses and homeowners under the name Glad Garbage Bags.

 

A Time Before the Can Liner

What did we do with waste before the invention of the can liner?

Well, if our American ancestors weren’t burying it or burning it themselves on their farms (like how we now handle municipal waste in our landfills), they would throw their waste in the street, where hogs, pigs, goats, dogs, or chickens might eat it.

They might dump their waste into a nearby ditch, river, or lake. Dirty sewage sometimes mixed into the drinking water, causing illness and disease. New York City began dumping its waste in the East River, a practice that made that body of water a smelly, germy mess.

Some states began to outlaw the hunting of vultures or even began to bring them into their states since these birds would eat waste and roadkill quickly and efficiently. Buildings and edifices were commonly infested with rats and cockroaches.

Benjamin Franklin began the first street cleaning service in America in 1757. He advocated that citizens dig holes to dispose of their waste and garbage.

As we learned more, the first landfill was opened in Fresno, California, in 1934 to help provide a more scalable and sanitary means of disposing of waste materials.

What About Trash Cans?

The first trash can in America was made of metal, and it first came on the scene in 1885. A Frenchman, Eugene Poubelle, is generally credited with the invention of the modern public “waste bin” in Paris, and his name is still used in France to refer to these receptacles. Poubelle is also credited with developing a system to collect and dispose of public waste.

Metal trash cans were supplemented by plastic trash cans in the 1920’s, but they still weren’t being used regularly with can liners until the 1970’s.

Back then, some common complaints about trash cans were that they were dirty and smelly. After a few weeks of holding all the waste generated by a typical public building or home, these containers would become quite ripe and need deep cleaning and disinfecting.

Enter the Can Liner – And All of Their Benefits

Can liners came on the scene and filled in the void to help protect public health, make waste collection easier and more efficient, and even protect the trash can receptacle itself.

Some of the key benefits of can liners include:

Public Health, Hygiene, and Safety

Can liners help to contain and keep germs and pathogens found in waste away from building occupants, which reduces the spread of pathogens and disease and protects public health, hygiene, and safety

a person expressing foul smell from the trash can

Odor Control

Can liners help to contain and keep odor-causing materials and germs away from building occupants and the waste receptacles themselves, which reduces malodors and improves indoor air quality

a person taking clean leak free garbage bag out to trash bin

Easy + Efficient Waste Disposal

Can liners help to allow for the quick and convenient containment, removal, and disposal of waste without having the continually clean the waste receptacle, which reduces the overall amount of time needed for waste disposal

Protection of Waste Receptacles

Can liners help to keep waste receptacles clean and free from scratches, dents, and other damage, which leads to their longevity and extends the time needed before replacement, saving money and landfill space

Spill + Leak Prevention

Can liners help to prevent leaks and spills from waste receptacles, which helps to keep the area surrounding waste receptacles clean


So, there you have it – the history of the can liner and the public benefits we receive from using it. Who would have thought they would become as ubiquitous as they are today when they were first invented back in 1950? And who can imagine modern life without them?

At BradyPLUS, we like to say that hygiene and safety are “in the bag” when you purchase can liners from us. Please contact your BradyPLUS Account Consultant today to learn more about all our can liner (and waste receptacle) options!
