Bag bag broken rate is particularly high why?

Bag packing bags of torn bags can also be interpreted as air tightness is poor, broken bags used in our production process is hard to avoid can meet again. But if torn bags rates were particularly high, this is not a normal phenomenon. When encountered such a problem, how can we to analyzes? In the search for the root cause, small make up that such a model, can help you quickly find the cause of the high rate of broken bags in summary: most bags break in what position the position of the breach can be divided into three conditions: 1, in hot pincer-like device, 2, on bags, 3, in the packaging film layers. By summing up the position of the crevasse, can further the cause of the search for more accurate. Observation: take a closer look at the bags break 1, in hot pincer-like device damage: a break with powder or foreign body, lesions have fold, b c lesions is 2, on bag broken: a broken mouth fixed in one place, b broken mouth, fillers are sharp, 3 c lesions had obvious crease, in thin film layers: a fixed in one between two layers of thin film, b is not fixed in between the layers of anatomy: matinee composite bags, mostly in the cause of the high breakage hot pincer-like device, as a result of poor heat sealing effect: a powder, it is because of static electricity, are attached to the heat sealing layer when filling powder, lead to poor heat sealing effect. In addition to static electricity, had better use anti-static heat sealing film. B there are foreign bodies, are generally not filaments thin film, is due to the packaging equipment have sharp hard objects on the incident, filamentous film, affect the heat sealing, inspection equipment, eliminate sharp hard objects. C has a fold, fold problems caused by the membrane devices. Good heat sealing knife, unsecured also causes; Heat sealing knife pressure is too large, complex film layer. Check the adjustment membrane device and heat sealing knife, final inspection heat sealing pressure adjustment. D like shape, is the heat sealing layer is too thin or not enough viscosity, heat sealing strength is too low. Heat sealing layer or replace the heat sealing film, most of the two on bag, if a fixed, it is pointed hard packaging equipment, Pierce packaging bags. Remove sharp hard objects, can solve the problem. B if it's broken mouth, filler is more sharp, is a poor puncture resistance of packaging materials, change to meet the needs of product sharp degree of resistance to Pierce packaging material. C lesions have crease, this is due to the poor fatigue resistance of packaging materials, under the received knead, folded in half and repeated forces, reflect on fracture, crack, resulting in damage. In a good material for fatigue resistance. Third, in thin film layers, this is the strength of composite packaging is too low. A fixed, choose low viscose viscous force of the two kinds of film, switch to other viscose. The asymmetry of coating is not fixed, viscose or too thin. By observation of the total price a a analyzes three steps, basically can put the bag breakage rate is too high to find out the reasons. Hope to be able to help each enterprise to exclude the worry, to use high quality composite bags.
