Good quality management is the pillar to improve the competitiveness of products, and has a huge role in improving the economic interests of enterprises. To develop the market with quality and to stabilize the market with quality is the action standard for flexible packaging enterprises to improve their product market competitiveness.
Flexible packaging enterprises should closely follow the advanced management concepts and methods, strengthen the research and application of their own management concepts and methods, and avoid relying on traditional empirical management methods.
First of all, according to the requirements of the quality system, determine the name, scope and responsibility of all kinds of data collected, and clearly specify the methods and ways of data collection, analysis and transmission, so as to provide original data accumulation for quality management.
Secondly, enterprises should use statistical and analytical methods to analyze the collected data, get valuable quality information, and then find out the development law of product quality, find out the existing problems, and effectively implement the quality control and improvement.
Third, quality control must take effective methods. For example, the control chart method, in the early stage of implementing total quality management, was very recognized that "quality management starts from control chart and ends with control chart", which shows that control chart method plays an important role in quality management.
Fourth, the key point of quality management is to achieve hierarchical management in the implementation of quality management. Hierarchical management means that employees perform their own quality management functions according to the division of responsibilities and different management levels.
Taking the sales process of flexible packaging enterprises as an example, each marketing personnel should count the quality problems reflected by customers on a monthly basis, classify and analyze them, find out the rules or common features, and feed back the information to the person in charge of the sales department. The person in charge of the sales department summarizes and analyzes the collected information on a monthly basis, finds out the rules or common features, timely revises the sales and after-sales service plan in combination with the customer satisfaction measurement results, formulates corresponding improvement measures, and reports the effective information to the leader or functional department in charge of the enterprise. The leaders or functional departments in charge shall comprehensively analyze the information reported by production, quality, sales, finance and other departments for analysis and processing, determine countermeasures and measures, and report them to the person in charge of the enterprise for decision-making.
From the above process, it can be seen that only when the quality management is carried out in all aspects of the business process, including financial analysis, production planning, technical development, quality inspection, etc., can the enterprise's quality management work be steadily promoted, the quality management system can be effectively operated, and the management activities can be carried out continuously. Secondly, we should focus on the evaluation and assessment of suppliers, and strengthen the analysis and control of specific problems such as sampling release.
Flexible packaging enterprises should follow the control principle of "product quality is made in the process", and identify the key product characteristics (technical indicators) and process characteristics that affect customer demand by creating a positive system operation environment, using quality function deployment and correlation analysis quality management tools. Through the establishment of specific process control standards, the use of statistical process control technology, the control chart and standard compliance chart as the main tools, the quality information of key products and processes are counted, analyzed and monitored, so as to effectively control many factors affecting the key characteristics of products, and master the laws of key variables in the production process The continuous refinement and optimization of the method can keep the quality characteristics of key products stable and meet the needs of customers.

In view of the characteristics of soft package enterprises, quality control should be carried out from two aspects in the production process.

One is the quality input control of raw materials. As the quality of raw materials is an important input of product quality, it directly affects the quality of processing procedures. For example, the quality of ink in printing process, the surface wetting tension of BOPP film, the quality of adhesive and solvent in dry compound process, the friction coefficient and surface wetting tension of film in aluminum plating process.
Second, strengthen process control. To identify the key quality characteristics of products, according to the key characteristics of different quality management methods, strengthen process control. For example, the key process is identified according to the key quality characteristics of flexible packaging products, and the key process is controlled.
For example, printing, extrusion and dry lamination are defined as key processes, and the equipment and devices such as speedometer and thermometer are effectively controlled. The specific control method is to test the equipment regularly, calibrate the instrument regularly, maintain the equipment regularly, and ensure the product quality depending on the normal operation of the equipment. To achieve the key process "three fixed", that is, fixed personnel, fixed process, fixed equipment.
Proofing is carried out before printing, and the process parameters in printing process such as ink viscosity, formula and ratio, drying oven temperature and speed are recorded. Before dry lamination, small sample trial production was carried out, and the binder ratio, mesh number of wire mesh, temperature of three drying channel and speed in dry composite process were recorded. Record the speed, pressure and peeling strength of extrusion compound process. First article inspection and patrol inspection during printing and extrusion lamination; unqualified products shall be stored in isolation and marked to prevent them from flowing into the next process. The process control chart can be used to control the key quality characteristics. For example, according to the regularly collected data reflecting key quality characteristics such as thickness of aluminum coating film, oxygen permeability of high barrier packaging bag, water vapor permeability and surface resistivity of anti-static packaging materials, the process control chart is drawn according to the collected data and time, so as to realize the monitoring of the production process.
The commonly used questionnaire method of flexible packaging enterprises is to collect the original quality data for analysis and processing, such as product defect questionnaire, unqualified reason questionnaire, process quality questionnaire, etc. The use of a variety of different management tools is based on the original quality data. The basic method is to strengthen the management of quality records. In the whole process of quality management system operation, various quality records, including original records, statistical tables and reports, should be used, such as internal quality audit records, management review records, contract review records, design review records, technical data and management document changes, distribution control records, qualified supplier files (including qualified supplier questionnaire and qualified supplier evaluation) List of qualified suppliers, evaluation form of qualified suppliers), equipment management records and files, parts repair (including maintenance and periodic point inspection records), process parameters of special processes, medium control records, seal management records, process control records, inspection and test records, appraisal records of measuring instruments, quality analysis records, quality assessment records and quality information processing records Record, unqualified product review record, employee training record and file, etc.
Quality record is the objective evidence to prove that the product quality meets the standards or customer requirements, and is also the basic requirement for the effective operation of the quality system. By strengthening the quality record, the causes of production waste are analyzed in time, and effective corrective and preventive measures are taken to reduce the waste; statistical analysis is also carried out according to the quality records, so as to master the product quality status and predict the quality trend; it can be said that the quality record clearly defines the quality rate of each process, effectively controls the production cost, and achieves lean production.
