Three -dimensional bag of non -woven fabrics

The utility model provides a three -dimensional bag of non -woven fabrics. The problem of present nonwoven sack processing troublesome, intensity is not high is solved. It is including the bag body and handle, handle and bag body looks rigid coupling, the bag body by a non -woven fabrics through folding antetheca, hou bi, lateral wall and the diapire of forming, the both sides of antetheca all backward the wall orientation roll over an ahead edge, a back edge is all rolled over to the antetheca orientation in the both sides of back wall, the both sides of diapire are upwards rolled over the base and are followed, ahead back following along on one side of corresponding is fixed through the welding mutually, ahead bottom along, back edge all with the base along fixing mutually through welding, ahead along, back along, base along " T " the font that the trace is the inversion that welds that ultrasonic bonding formed. The beneficial effects of the utility model are that, bag body structure through the integral type makes the intensity of product increase, has reduced the time and the time of manufacturing moreover and has reduce manufacturing cost.
