The Process of Plastic Bag Production

We can see Plastic bags these days nearby us everywhere. We combine them for such different uses as freezing food, clinching a sandwich, carrying grocery products and lugging books. The process for producing plastic bags is similar across manufacturers, while some may enhance a few exclusive steps or use specialized kit. There are two steps to make a basic bag is given below.

Extrusion Process

An extruder heats polyethylene plastic resin pellets to around 500 degrees Fahrenheit, enough to melt the pellets. A screw inside the extruder forces the molten plastic through the machine and pushes the material through a die that controls the thickness of the product. Air forces the emerging plastic film into a bubble that travels upward about three stories in a cooling process. After pinching out the air and flattening the bubble, the film is cut to size and wrapped on a spindle.

Converting Film to Bags

A conversion department unpacks the roll of film and cuts it with a heated knife that both seals the sides of the bag and cuts it to size. The conversion department also adds any special appearances needed for a completed bag. Dies cut out handles, wheels produce gussets, and zippered seals get attached with heat or by ultrasonic means. Any printing may be done after the bags have been converted, or in a separate department between extrusion and conversion.
