In the past ten years, the printing industry has developed very rapidly, the competition is very fierce, the profit margin of the company is getting smaller and smaller, and the production quality management is difficult to keep up. In response to this situation, we 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: formulate 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 conduct training according to problem points.The first step: According to the key factors affecting the quality of the plastic flexible packaging production process, formulate the production quality key control card. How to find key control points to ensure product quality, first of all, we need to understand the process of forming quality problems of plastic flexible packaging, list the key factors affecting quality, and then control them. 1quality loss caused by the marketing process. Sometimes we do plastic flexible packaging because we do not understand customer requirements during the production process, resulting in quality loss. These problems can be listed for external source control. This requires marketing personnel to fully understand the customer’s product characteristics and ingredients, packaging bag quality requirements, packaging process, etc. in the process of communicating with customers and record them in writing, and formulate customer requirements when the production task is issued. The material, structure and other aspects can be reviewed, so that the production department personnel can truly understand the customer’s requirements and carry out quality management. What quality follow-up can be focused on according to customer requirements. So as to effectively prevent quality problems. 2, quality loss caused by the production process. The production process of most companies that do plastic flexible packaging is printing——complex——Divide——Four parts of bag making. In the previous production quality management, understand what causes the biggest quality loss of each process, find out the key control points according to the reasons, formulate the operation and inspection standards of the key control points, and target the standards during production; The three-layer quality control system consisting of inspection, workshop director supervision and quality inspection can effectively control solvent residues and other quality problems.The second step: According to the production process, the first piece is confirmed according to the process, and the quality control of each semi-finished product or bag-making product is carried out. We formulate the first item confirmation item form for printing, compounding, slitting and bag making in the management production process, and proceed item by item. Every time you roll down, you need to take samples to find problems and improve them. For example, for printing, use scrap for proofing, check the color first, and change to the original printing if the color is accurate500mAfter changing the roll, take a sample for the first confirmation, and check again the color, text, pattern, size, overall printing effect, solvent residue and other quality problems. If there is a problem, it will be improved in time, and if there is no problem, it will be mass-produced. In this process, each roll of material needs to be sampled to review the quality when it is unrolled. It is also necessary to implement the three-level quality of the captain’s self-inspection, the workshop director’s supervision and the quality inspection. Check the system, so that quality problems can be effectively controlled. Even if there is a quality problem, the amount of loss will not be very large, and it will not be scrapped in half or the whole batch.Step 3: Keep the physics of the production process in a controlled state, with input physics equal to the finished or semi-finished product. When we do plastic flexible packaging, we must manage according to the order, pick materials according to the order, and arrange the production according to the order to the machine and people. When each production link is in production, it is necessary to record the volume number, weight and length, time, and operator each time the volume is unloaded, and then fill in the material balance sheet with the materials used on duty, production output, and waste to maintain the balance of materials in each link. The physical balance of the process, if there is an imbalance, the cause can be found and analyzed, and the traceability of the product is also achieved.Step 4: Train according to the problems in the above three steps. Improve the performance of production operators, and thus a stable and continuous production process is formed.
