MAKING METHOD OF AN ENVELOPE DOUBLE LAYER PAPER FOR MOISTURE PROOF AND AN ENVELOPE DOUBLE LAYER PAPER

摘要

The present invention comprises the steps of laminating the kraft paper released from the first feed roll and the film paper released from the second feed roll superimposed (S1); At the starting point where the kraft paper and the film paper are laminated, the insoluble and odorless polyethylene (PE) adhesive, which is melted at 170 to 180 ° C., is discharged from the extruder with a thickness of 1 to 2 mm, so that the kraft paper and the film paper are discharged. To make the adhesive state possible (S2); Immediately after attaching the kraft paper and the film paper, the kraft paper and the film paper are press-bonded by the adhesive and the adhesive is made by the cooling roll while passing between the press rolls which are brought into contact with each other and the cooling roll having a surface temperature of 16 to 17 ° C. Step of making the solidify quickly (S3); is a manufacturing method of the double-wall paper for moisture proof, comprising;In addition, the present invention is to provide a moisture-proof double zone paper produced by the above method.;Moisture proof double band paper, method of making double band paper, PE adhesive
