Packaging has been the need of human kind from early time for storing, transporting, preserve foods, goods and products. With the dramatic innovation of technology, the interaction between people from different areas, different countries increase and demand of trading rises day by day, packaging in a most convenience way is necessary and vital. Plastic bags have been introduced to meet that demand as an excellent solution. But just how are plastic bags are produced?

The 1st process is blowing film or called extruding film. All the materials will be put into extruding machine to make big plastic film roll. In this steps, workers or technicians must control the bag rolls into smooth appearance.

The second step is printing process which is mainly used for shopping bags which many companies could customize the printing image with their logo, brand name, information about products.

And finally there is the cutting and sealing process. The plastic rolls are put into cutting workshop to make it into different shapes and different handles. There are a lot of cutting machines available served for different handles: T-shirt, die cut, soft loop, patch handle, rigid, flat merchandise, etc. For the special kinds such as drawstring plastic handle bags, rigid plastic handle bags, soft loop plastic handle bags, they are usually required some manual steps which can not be implemented by automatic machine. In manual workshop, workers have to sew the handles into the bags, putting the cardboard into gussets (customized to customer's requirement) and punching in the hole.
