In recent ten years, the printing industry has developed very rapidly and the competition is very fierce. The profit space of colleagues is getting smaller and smaller, and the production quality management is difficult to keep up with. In view of this situation, the manufacturers of perforated fruit bags provide a four step plastic flexible packaging production quality management method to improve efficiency, standardize management, effectively control quality, reduce costs and improve customer satisfaction.
The four steps are: to establish the key control points of production quality, first article confirmation and sample signing system for each volume, material balance and traceability in the production process, and finally carry out training according to the problem points.
The first step: according to the key factors affecting the quality of plastic flexible packaging production process, the key control card of production quality is formulated. How to find the key control points to ensure the quality of products, first of all, we need to understand the formation process of plastic flexible packaging quality problems, list out the key factors affecting the quality, and then control them.
1. Quality loss caused by marketing process. We do plastic flexible packaging sometimes because the production process does not understand customer requirements, resulting in quality loss, we can list these problems for external source control. This requires the marketing personnel to fully understand the customer's product characteristics and ingredients, packaging bag quality requirements, packaging process, etc., and make written records in the process of communicating with customers, and formulate the customer requirements attachment sheet when the production task is issued. In this way, the process and technology department can audit the material and structure, and the production department personnel can really understand the customer's requirements Quality management,. What quality follow-up can be carried out according to customer requirements. So as to effectively prevent the occurrence of quality problems.
2. Quality loss caused by production process. The production process of most enterprises making plastic flexible packaging is printing - compounding - cutting - bag making. In the previous production quality management, we should know what causes the maximum quality loss of each process, find out the key control points according to the causes, formulate the operation and inspection standards of the key control points, and check the standards during production; implement the three-layer quality control system composed of the captain's self inspection, workshop director's supervision and quality inspection, so as to effectively control the residual solvent and other quality Quantity problems occur.
Step 2: the manufacturer of perforated fruit bags shall confirm the first article according to the production process and process, and control the quality of semi-finished products or bag making products each time. We develop the first article confirmation project form for printing, compounding, slitting and bag making in the management and production process, and carry out item by item. Every time the volume is down, we need to take samples to find problems and improve them. For example, in printing, using waste proofing, first check the color. If the color is accurate, change the original material and print for 500m, then change the volume to sample for the first piece confirmation, and then check the color, text, pattern, size, overall printing effect, solvent residue and other quality problems again. If there is a problem, it should be improved in time. If there is no problem, mass production will be carried out. In this process, the quality of each coil needs to be sampled for quality audit. A three-layer quality control system composed of the captain's self inspection, workshop director's supervision and quality inspection should be implemented, so as to effectively control the occurrence of quality problems. Even if there are quality problems, the amount of loss will not be very large, so as not to scrap the half batch or the whole batch.
Step 3: keep the physics of the production process under control, and input physics equals to finished or semi-finished products. We do plastic flexible packaging must be according to the order management, according to the order material, according to the order arrangement production, implements to the machine, the human. During the production of each production link, it is necessary to record the volume number, weight and length, time and operator for each rewinding, and then fill in the material balance sheet with the materials, production output and waste materials on duty, so as to maintain the material balance of each link and the physical balance of the process. In case of any imbalance, the causes can be found and analyzed, and the traceability of the products can be achieved.
Step 4: the manufacturer of perforated fruit bags should be trained according to the problems in the above three steps. Improve the performance of production operators, so as to stabilize the continuous production process. http://www.dgbpk.com/
