first of all, to make a composite bag, you must first order the materials, because if the materials have not been compounded for a long time, it is not very good, so we need to buy it now, so normally, if a composite packaging bag is not printed, it will take 10 to 12 days. if it is printed, it will take about 15 days. so when we are ready to make a composite bag, we should contact the manufacturer 20 days in advance to prepare some design drafts in advance.

after the materials are customized, if you don't need to print, you can directly go to the compounding machine to compound the materials. in this way, one layer of materials will become two or more layers. if you need to print, you have to go to the printing machine to print. normally, the printing surface of the composite bag is inside the upper surface material. after printing, you can go to the compounding machine to compound the printing surface with one or two layers of materials the composite is finished. after printing and compounding, the materials are put into the curing room for curing, and the composite bag can be made after the glue in the compounding time is completely dried for 24-48 hours or longer. the forming machine is called bag making machine. after the bag making machine on the composite film is debugged by the master, we can cut out the bag shape we want.
