Very not easy to produce good product instant scrap, the reason in it? | | food industry information packaging manufacturers

Believe that a lot of flexible packaging enterprises have encountered similar problems, but worked so hard to produce good film semi-finished products in composite process down into success or failure, very regret. Estimated that most of the enterprises will cause due to workers operation, actually may be composite machine network cable roller glue problem. 1. Flexible packaging plant in buying dry compound machine, if there are no special requirements, general original machine with glue line roller is in commonly 80 - 120 line. But if you want to do quality requirements higher compound bag will glue line roller for composite machines rational selection, determine the line number of network cable roller, in order to improve the quality of compound bag products. 2. Network cable roller is a lot of more phyletic, used in flexible packaging dry compound machine is only two kinds: one kind is tapered, namely: type rectangular pyramid and edges. Currently used in flexible packaging dry compound machine is mostly used rectangular pyramid type of network cable roller. But surely, the number of network cable roller line net hole depth should also be in a certain range, the network cable roller mesh hole deeper, the greater the capacity of the mesh, the more adhesive transfer, network cable roller service life will be shorter, therefore, should pay attention to when choosing network cable roller net hole depth, can be directly with the manufacturer of the cable roller. 3. The method of making the network cable roller, generally can be divided into two kinds: one is the electric carving; The second is the special equipment for extruding. In the mode of production, the different network cable roller mesh is different, in the use of the form is different also. In the use of the compound machine blade, should strictly for blade Angle adjustment, also can control the amount of glue. Basically all adopt the special equipment for extruding general manufacturer. Network cable roller line number according to the quality requirements of composite bags to choose correctly. 4. The choice of the specific methods: making ordinary compound bag can use one-component adhesive, with 80 line - 120 line glue line roller. Making general composite bags, using two-component adhesive, generally can choose 120 - 160 line network cable roller. Do the packing bag of high-grade, more strict in the composite, using the two-component polyurethane adhesive can choose generally line - 160 200 line network cable roller. Can be concluded that on the conditional enterprise can spare more cable on the different rubber roller in order to use, after use, be sure to mesh point of network cable roller clean, in case the cause plugging. If it is a long time need not, must clean with brush and ethyl repeatedly, finally to wipe with dry cloth.
