Quality

Raw material purchase control
Quality supplier selection: Establish long-term and stable cooperative relations with reputable and qualified raw material suppliers. Conduct strict evaluation and audit of suppliers, including their production capacity, quality assurance system, raw material quality, etc., to ensure that the purchased plastic raw materials meet the high quality requirements.
Incoming inspection: Each batch of raw materials is subject to strict inspection when entering the factory. The inspection items include physical properties, chemical properties and appearance of raw materials. For example, the melting index, density, tensile strength and other indicators of plastic particles are tested to ensure that they meet the standards for the production of high-quality plastic garbage bags and ensure product quality from the source.
Production process quality control
Production equipment maintenance and management: regular maintenance and calibration of production equipment to ensure the normal operation of equipment and the accuracy of process parameters. Advanced production equipment can ensure the production accuracy and stability of plastic garbage bags, such as the temperature control of the extruder, the wind speed and tension control of the film blowing machine, which have an important impact on product quality.
Process parameter monitoring: In the production process, strictly monitor the process parameters, such as temperature, pressure, speed, etc. The advanced automatic control system records and adjusts parameters in real time to ensure that every production process is carried out in the best condition. For example, during the film blowing process, parameters such as the blowing ratio and traction speed are precisely controlled to ensure the thickness uniformity and strength of the plastic film.
Online quality testing: Set up multi-channel online quality testing links, the use of advanced testing equipment for real-time detection of plastic garbage bags in production. If the laser thickness gauge is used to dynamically monitor the thickness of the film, once the thickness deviation is found to exceed the allowable range, immediately adjust; Tensile testing machine is used to sample the tensile strength of garbage bags to ensure that the products meet the quality standards.
Finished product quality inspection
Appearance inspection: Check the appearance of each finished garbage bag, including whether the color is uniform, whether the surface is flawed, and whether the printing is clear and complete. Remove the products with appearance defects, and ensure that the garbage bags delivered to customers are of good appearance quality.
Dimensional accuracy testing: The use of professional measuring tools to accurately measure the size of the garbage bag to ensure that its length, width, thickness and other dimensions meet customer requirements and enterprise standards. Strict size control contributes to the adaptability and stability of garbage bags during use.
Performance test: Comprehensive performance test of finished garbage bags, including tensile strength, elongation at break, puncture resistance, sealing performance, etc. The durability and reliability of garbage bags under different conditions are tested by the test method that simulates the actual use scenario. For example, a certain weight object is put into a garbage bag, and tests such as lifting and falling are carried out to detect the carrying capacity and anti-cracking performance of the garbage bag.
Quality traceability and continuous improvement
Establish a quality traceability system: establish detailed production files for each batch of products, record raw material information, production process parameters, production time, inspection results and other key data. Through the quality traceability system, the root cause of quality problems can be quickly and accurately found, and timely measures can be taken to correct and prevent.
Data analysis and continuous improvement: Analyze the quality inspection data regularly and summarize the distribution and change trend of quality problems. According to the data analysis results, continuously optimize the production process, improve the quality control measures, and continuously improve the product quality level. At the same time, actively collect customer feedback, customer opinions and suggestions into the important basis for quality improvement, in order to meet the continuous improvement of customer quality requirements.
