Plastic PP/PE woven sack bag making machinery: outer or liner PP/PE lamination machine for the colorful BOPP fertilizer,rice,cement bags

Plastic Laminating machine is making use of the good adhesive property of polypropylene and polyethylene during the melting status, this machine adheres and laminates paper and color-printed woven packaging bags. Laminating melted polypropylene and polyethylene film on woven bags produces laminated woven bags.

Laminating on the film and paper directly, or laminating color-printed OPP and BOPP film on both sides of these bags produces colored packaging bags for instant noodles, melon seeds and various other foods, It is suitable for coating on the Circular PP/HDPE Woven Fabric.

This machine breaks the former shortcoming of only using expensive special coating plastics for film instead, it use common polypropylene power material plus a little polyethylene. Under the molten state, it has a peculiar gluey function to daub film between braiding bag and paper or braiding bag and BOPP film or on braiding film and make all kinds of compound braiding bags through pasting and cutting by pressure.

As a result, it greatly reduces the cost and wins better market for compound bags. The extruder of this unit can control the melting temperature automatically. It uses no-class speed adjuster to adjust the thickness of melting film, two-side or one-side film, double-mold head and the width of coating. The timber, which can be adjusted crossly, has auto-cutting side, blowing side and the M-folding side. If the device is cut off, the whole structure will operate in the same step. Moreover, this machine can also adjust the length of cutting bags by using no-class speed adjuster changing gears.

Because of the special and excellent designs and techniques on the machine, we got three China national patents, one of them was awarded Eureka World Invention Golden Medal Certificate. Patent No.: 99201034.7, 99247820.0, 99247820.0 (for Eureka Invention Award).
