Nozzle bag processing

　　Nozzle bag is composed of suction nozzle and the self-supporting bag, bag and put in production through the nozzle bag two links to the end of the suction nozzle bag manufacturing. Each link has a higher demand for the technology, if hold bad, will show up bag, the bag breaking, leakage and other quality problems in use process, obviously nozzle bag of this quality is not qualified, then in the nozzle bag production process to prevent the condition of hair do?

　　In the production of self-supporting bag, special attention should be paid to punch, a bag bottom, bottom sealing and other aspects, especially the joint parts of self-supporting bag four layer and the two layer is easy to attack the torn bags, only the horizontal seal cutter is not, want to install the heat sealing knife, but also to enhance the heat sealing parts. The other, spout pouches needs opening function better, it is not easy to install suckers mouth mouth; the friction coefficient of the appearance of small bag, bag to eradicate the appearance of static electricity, prevent between the bag and the bag mouth is not conducive to attack adsorption bag sealing machine.

　　At present, the self-supporting bag with suction nozzle which is mainly through two ways: manually installed suction nozzle, heat sealing nozzle. After the heat conduction temperature makes the mouth to mouth way, ablation and PE sealing and bag layers are welded together.

　　Production of nozzle bag end will be after vacuum sealing apparatus test Shi Bushi seal to prevent leakage, damage, present situation, with the physical function of tensile tester test stand bag: the maximum acceptable tensile force, pressure test the pressure testing instrument.
