Carrying laundry detergent bags order, are you still in trouble?

Laundry detergent bag is a high demand, high value-added products, production should pay special attention to the key control points, pays special attention to the quality inspection, real effectively completes the testing and evaluation, to the rapid development of laundry detergent market place. As the matures of flexible packaging technology and innovation, a growing number of laundry detergent packaging in the form of flexible packaging. Compared with the plastic containers, flexible packaging can reduce costs, capacity of the same flexible packaging bags below 0 plastic containers spreads. 3 to 0. 5 yuan/a; At the same time, logistics transportation cost can save 20%; Flexible packaging bags more environmental protection, printing more exquisite, be helpful for shelf display effect. A, the classification of soft packing my bag from the packaging of the capacity to distinguish: by far the most common is 500 ml, 380 ml, 600 ml, 900 ml, 1 l, 1. 3 l, 1。 8 l, 2 l, 2 even. The large volume of 1 l such products. From packing to distinguish the form of: three bags, production technology is relatively simple, mainly used for the product under 500 ml; Special-shaped self-supporting bag, has the very good display effect, easy to dump, supplement plastic bottle pack; Add mouth self-reliance bag, combined with the double advantages of plastic containers and flexible packaging, lighter and easier to filling and dumping, it can be used a few times, the display effect is good. Manner are straight mouth and oblique mouth mouth two ways, mouth is mouth straight welded on the top of the bag, oblique oblique mouth is the mouth of welding in the bag, laundry detergent packaging generally USES oblique mouth way. Oblique mouth self-supporting bag abnormity self-supporting bag 2, 1, the problems that should pay attention to production and processing of leakage discharge is the most common liquid bag, which is the most headache problem, after filling liquid, even if only a pack of leakage in a case of products, also can contaminate the whole box products. The cause of leakage mainly has: ( 1) Sealing side size. （ 2) Bags and bag burst Angle. （ 3) Peel strength between the layers. （ 4) The flexibility of the material shortage. （ 5) Rolls with holes. （ 6) Poor sealing after filling, sealing the excessive temperature and pressure, cause heat sealing laminated thin, sealing strength drop, leakage of liquid from the heat sealing. 2, printing bad appearance of bad appearance, including tinted, cutter line, pollution, off color, ink, etc. , and other printing products, need to go from two aspects of the material and production process analysis and control. 3, stand stand bad bad, is refers to the liquid bag filling, bag presence of curl at the bottom of the cave, or bag bag body & other; Collect waist & throughout; Phenomenon, on the product shelves display effect. Liquid self-supporting bag stand for sexual reasons, mainly include: the design of material structure has certain defects, material not enough stiffness, slants thin thickness, etc. Three, in the production of key project detection laundry detergent self-supporting bag is a high demand, high value-added products, production should pay special attention to the key control points, when pays special attention to the quality inspection, real effectively completes the testing and evaluation, to the rapid development of laundry detergent self-supporting bag market place. Laundry detergent self-supporting bag production, the key test items include: 1, compression: general ML&le time for 5 min capacity; 500500 - 1000 > 1000 pressure Kg1001502502, drop: the bag in the height of 1. 2 m in free fall, which requires the continuous three bags, leakage is judged to be unqualified. 3, bag making false: if there is a bag sealing, filling liquid after, very prone to leakage. 4, sealing buckling: small buckling in pincer-like device, influence on the heat sealing strength is not big, but for the bag sealing, has great effect on permeability, good need to adjust the bag making of temperature, pressure, and the selection of heat sealing plate, the heat resistant fabric choice. Quality traceability, need to set up perfect quality traceability system, do a good job retention samples for future reference. Once an exception occurs, can to the fastest speed, with the least cost.
