Plastic Bags: How They're Made and What They Do

Poly bags are made from crude oil and natural gas, and the process itself is often called the “tubular film process.” The polythene melt is blown into an annular tube, where air is blown to make the melt swell. The hot plastic is blown with more air to cool it. The plastic film is cooled and flattened with rollers and either kept like that or slits are cut into it. If it is kept flat, the film is sealed with another sheet of film or cut to make a bag with one side left unsealed for the opening.

One of the most interesting things about making poly bags is that there are so many different options in how they result that the choices are almost endless. From wicketed bags to newspaper bags, header bags and bread bags to plastic bags and staple bags, there are poly bags for anything! And if you want to advertise on your poly bags, it’s easier said than done. You can choose a range of colors that will attract the eye and make your plastic bags the cat’s meow. So if you run a small business and need some plastic bags, don’t just settle, get some poly bags that will bring you a return.
