The reason and the control methods of organ bags easily torn bags

Now, many customers are constantly improve the yield of active process, will be more and more strict to the requirement of fruit packaging business. Organ bag there are two kinds of common production process, is a kind of seal with gusset, another kind is the four bag edge-sealing organ. The two process there is a common need to pay attention to process control point: organ, organ bags to derive a lot of other types at the same time, the bottom gusset and eight edge-sealing organ bags. In numerous type bag bag, seal with gusset inside empty than do most other 3-side type, but also can save money, so it's popular with customers. Organ bags commonly used in clothing, hardware, electronics, food, daily necessities packaging, application is very extensive. For packaging below 300 g content, organ bags, the production of basic does not exist too much of an issue, as the materials in use and production process, enterprise applications are very mature. But for more than 300 g of packing materials, especially in terms of the contents of powder, small particle, comparison test produce flexible packaging manufacturers. The content for the customer's automatic packaging equipment is also a big test. A bit common problems of organ and organ level and handover the sealing position with the position of a cascade, namely on both sides of the organ in the transverse seal only two layer heat sealing material, and the organ of the transverse sealing side will have four membrane need heat sealing, so in this position will be a stepwise transition sealing side. And heat sealing mold base in a horizontal plane, a lot of the time the bag is a break from here. The delivery location for horizontal sealing and organ question which is easily broken bag professional manufacturer of flexible packaging packaging to a lot of ways to solve, now can effectively reduce the organ bag bag broken rate. Second, the common solution 1, the improvement of raw materials on the improvements are mainly from raw materials increase its physical properties, such as the inner base material selection on brittle crack resistance, resistance to stretch and fold, increasing flexibility, toughness, improve physical and mechanical properties of materials, reduce the yield in the process of organ line a chance to be injured. Or by increasing the thickness of the material to improve. At the same time, you can also use the toughness better glue, enhanced resistance to fold function, improve packaging resistance to fracture, rub resistance. 2 organ bags, improvement of material structure generally choose BOPP/CPP, PET/PE, BOPP/PE, PA/PE, PET/AL/PE, PA/AL/PE, PET/PA/PE structure, when a structure is relatively weak, can change the physical performance is excellent material to replace, or increase the structure layer to increase the strength of the whole bag. From fabric bending, mechanical tensile mechanical properties into consideration, such as NY is better than that of PET, PET is better than that of BOPP, of course, if use NY instead of PET this kind of practice, will certainly increase the cost. We can also by increasing the structure layer to improve the organ bag material used. This is also a good idea, but the cost will increase a lot. Increase in material layer, have to be very careful, carefully evaluate increase after material performance brought by the change.
