A METHOD OF MAKING ROLL ZIPPER BAG AND ROLL ZIPPER BAG USING THE SAME

摘要

The present invention relates to a method for manufacturing a roll zipper bag and to a roll zipper bag produced through the same, and more particularly, a raw material input in which a base material including at least one of linear low-density polyethylene (LLDPE) or low-density polyethylene (LDPE) is put into a hopper. Step (S100); and the molten base material between the inner casing 230 disposed inside the outer casing 220 and the outer casing 220 through the heated cylinder 260 and the injected base material A pressure feeding step (S200) which is extruded by the discharge ring 210 and is provided to be transferred to the extrusion molding die 200 including the cooling air port 240 at the central position of the roll zipper die 250 and the inner casing 230 and the base material passing through the extrusion mold 200 is cooled and provided to be folded into the front and back surfaces, and the female zipper 101 and the resin zipper 102 are opposite to each other on one side of the back surface. 101) and the base fabric generating step (S300) provided to form a roll zipper bag fabric 100 in which an opening is formed by being cut outside of the resin zipper 102; and the base fabric generating step (S300). A fabric winding step (S400) provided to wind the roll zipper bag fabric 100 on a take-up roll; and the roll zipper bag fabric 100 wound in the fabric take-up step (S400) into a cutter. A fabric input step (S500) provided to unfold the roll zipper bag fabric 100 through a cutting input roll; and the input progress direction of the roll zipper bag fabric 100 input through the fabric input step (S500) to be perpendicular to the direction A fusion step (S600) in which the front surface and the rear surface are fused at a predetermined interval to form a fusion line 120; and a pre-cut line 110 in parallel with the fusion line 120 formed in the fusion step (S600) ) a cut line generation step (S700) provided to form; and a zipper bag winding step (S800) provided to wind the roll zipper bag fabric that has passed through the cut line generation step (S700); a roll zipper bag manufacturing method including; rolls produced It relates to providing a zipper bag.
