The production process of the ton bag is: the woven fabric is printed, cut, and sewn to become a ton bag. Depending on the equipment used, it can be cut first and then printed, or printed first and then cut. Automatic cutting and sewing can continuously complete printing, cutting, sewing and other processes, and can also be made into valve bags, bottom bags, etc., for flat woven fabrics, the bag can be made after seaming and bonding.
The process indicators of plastic ton bag making are mainly appearance tolerance size, seam bottom direction and seam edge direction breaking force, the clarity of printing ink and the cleanliness of other parts after printing, the accuracy of layout position, stitching stitches, needles Distance, and the lack of stitches, thread breakage and other requirements.
Composite plastic ton bag
The production process of two-in-one composite plastic ton bag is to compound or coat woven cloth, coating material and paper or film. The obtained tube cloth or piece of cloth can be cut, printed, stitched and made into ordinary seamed bottom bags, or it can be punched, folded, cut, printed, and stitched to make cement bags. The obtained piece of cloth, It can be glued, printed, cut, paste-bottomed, and made into paste-bottom bags. It can also be welded, rolled, and made into tarpaulin and geotextile. The key to the composite bag making process is composite.
The principle of coating is to coat the resin on the woven fabric of the base material in a molten state. Only the molten resin is coated on the woven cloth and immediately cooled to obtain a two-in-one woven cloth. If the molten resin film is sandwiched between woven cloth and paper or plastic film during compounding, and then cooled to obtain a three-in-one woven cloth coating, it can be coated on one side of a flat fabric to obtain a piece of cloth, or it can be coated on both sides of a tube cloth. To obtain a coated tube cloth. The coated woven fabric can be printed, cut, and stitched into various bag shapes, and the wide coated fabric can also be rolled up as a tarpaulin before leaving the factory.
