The production process for two-in-one or three-in-one composite plastic bags is to compact or coat the woven bag with compostie or coating materials,paper or film, and then get the resulting cylinder of cloth or a sheet of cloth. The cylinder of cloth can be cut, printed, stitched and made into bags with conventional bottom seamed. It can also be perforated, folded, cut, printed, stitched, and made into cement bags. The obtained sheet of cloths can can raphe bondied, printed, cut, sticked and made into bags with the end pasted.It can also be welded, coiled and made into tarpaulin or geotextile.
The key process for making composite bag is compact. The principle of the resin coating is coating the substrate in a molten state on the woven cloth. If the molten resin is coated onto the woven cloth and immediately cooled, you can get only a two-in-one woven. During the coating process,if the molten resin film is sandwiched between the woven cloth and the paper or plastic film and then cooled, you can get three-in-one composite plastic bags. The coating can be applied to the single side of the flat woven and the sheet of cloth can be obtained, or applied to the double sides the cylindrical of cloth and the coated cylinder of fabric can be obtained. The coated woven can printed, cut, sewn and made into various types, and the wide-coated cloth can also be used as tarpaulin.
