How is a composite plastic woven bag made?
How is a composite plastic woven bag made? First of all, it is necessary to distinguish the production process of composite plastic woven bags, such as one-in-one, two-in-one and three-in-one, by combining or coating the woven fabric, the coating material and the paper or film. The obtained cloth cloth or piece cloth can be cut, printed, stitched, made into a common sewing bottom bag, or punched, folded, cut, printed, stitched, made into a cement bag, and the obtained piece cloth, It can be bonded, printed, cut, and bottomed in the middle seam to make a bottom bag. It can also be welded, coiled, and made into tarpaulin and geotextile.
The key to the composite bag making process is compounding.
The principle of coating is to apply the resin to the substrate woven fabric in a molten state. Only the molten resin was applied to the woven fabric and immediately cooled to obtain a two-in-one woven fabric. If the molten resin film is sandwiched between the woven fabric and the paper or the plastic film during the compounding, and then cooled to obtain a three-in-one woven cloth coating, the flat fabric can be coated on one side to obtain a sheet cloth, or the double-sided cloth can be coated on the cloth. Repeat, get the coated cloth. The coated woven fabric can be printed, cut and stitched into various bag types, and coated in a wide range.
