Plastic Garbage Bags- Plastic Trash Bags-Trash Can Liners
Harry Wasylyk was a Canadian inventor from Winnipeg, Manitoba, who together with Larry Hansen of Lindsay, Ontario, invented the disposable green polyethylene garbage bag or trash bag also called trash can liner.
Plastic Garbage bags or Plastic Trash Bags or trash can liners were first intended for commercial use rather than home use.
The plastic garbage or plastic trash bags were first sold to the Winnipeg General Hospital for use as trash can liners. However, Hansen worked for the Union Carbide Company in Lindsay, who bought the invention from Wasylyk and Hansen.
Union Carbide manufactured the first green plastic garbage or trash bags under the name Glad Garbage bags for home use as trash can liners in the late 1960s.
How Plastic Garbage bags and Trash Bags are Made
Plastic garbage bags or trash bags are made from low density polyethylene, which was invented in 1942.
Low density polyethylene is soft, stretchy, and water and air proof. Polyethylene is delivered in the form of small resin pellets or beads. By a process called extrusion, the hard beads are converted into bags of plastic.
The hard polyethylene beads are heated to a temperature of 200 degrees centigrade. The molten polyethylene is put under high pressure and mixed with agents that provide color and make the plastic pliable.
The prepared plastic polyethylene is blown into one long tube of bagging, which is then cooled, collapsed, cut to the right individual length, and sealed on one end to make a garbage bag or trash bag.
