In the bag production process, quality control is a very important link. Among the many quality control links, the final random inspection (FRI) is undoubtedly a key step to ensure product quality. This article will introduce in detail the importance, inspection content, and implementation methods of the final random inspection in the production process of bags.
Since Chiterion bags have been a professional cooler bag manufacturer since 2007, and we will take cooler bags inspection for example.
1. The importance of FRI
As a product widely used in the cold chain transportation of food, medicine, etc., the quality of cooler bags is directly related to the safety and effectiveness of goods during transportation. Therefore, it is very necessary to ensure that every cooler bag meets the quality standards before leaving the factory. The final random inspection is to confirm the quality level of the entire batch of products by sampling a certain proportion of products before the products are packaged and ready to leave the factory.
2. Inspection content
During the final random inspection process, the cooler bags need to be comprehensively inspected, mainly including the following aspects:
(1) Appearance inspection:
Overall appearance: Check whether the appearance of the cooler bag is beautiful and generous, and whether there are obvious stains, damage and color difference.
Seam quality: Check whether the seams are flat and uniform and whether there are skipped threads, broken threads, open threads, and other problems.
Zipper and other accessories: Check whether the zipper is smooth and whether there is any jamming, and whether other accessories such as buttons and handles are firmly installed.
(2) Size and capacity inspection:
Size: Use measuring tools to ensure that the length, width, and height of the cooler bag meet the design requirements.
Capacity: Check whether the actual capacity of the cooler bag is consistent with the marked capacity to ensure that it can achieve the expected storage effect during use.
(3) Insulation performance inspection:
Insulation time: Through experiments, test the insulation time of the cooler bag under specific conditions to ensure that it can maintain the internal temperature within the specified time.
(4) Material inspection:
Internal and external materials: Check whether the internal and external materials of the cooler bag meet environmental protection requirements, whether there is any odor, and whether it is durable.
Insulation material: Check the quality of the insulation material to ensure that it can effectively insulate during use.
(5) Functional inspection:
Waterproof performance: Through experiments, test the waterproof performance of the cooler bag to ensure that it can effectively prevent external moisture from penetrating during use.
Durability: Simulate the actual use environment and test the durability of the cooler bag to ensure that it can maintain good condition for a long time under normal use conditions.
3. Implementation method
To ensure the scientificity and accuracy of the final random inspection, a detailed implementation method needs to be formulated. The following are the general steps for the final random inspection during the production process of cooler bags:
(1) Determine the sampling ratio:
The handbag industry generally samples according to the AQL Sampling Plan tableⅡ. Based on Industrial Standard - Critical 0; Major 2.5; Minor 4.0. Our Internal Standard is more strict, it’s Critical 0, Major 1.5, Minor 4.0. Please see the table below for details:
For example, if our the order is 10000pcs, the sample size is 200pcs. According to the bag industrial standard, the acceptance level is Critical 0, Major 10, Minor 14. But our internal acceptance level is Critical 0, Major 7, Minor 14.
Random sampling: According to the sampling ratio, a certain number of cooler bags are randomly selected from the production batch to ensure the randomness and representativeness of the sampling.
(2) Inspection preparation:
Number and register the selected cooler bags and prepare the required inspection tools and equipment.
(3) Implementation of inspection:
According to the predetermined inspection content and standards, check the selected cooler bags one by one and record the inspection results.
(4) Result analysis:
Statistically analyze the inspection results to determine the quality level of the entire batch of products. If unqualified products are found, decide whether to rework or use other treatments based on the reasons and severity of the unqualified products.
(5) Report writing:
Write a detailed inspection report, including sampling conditions, inspection content, inspection results and treatment opinions, etc., to provide a basis for subsequent quality control.
4. Conclusion
As the last quality control checkpoint in the production process of cooler bags, the importance of the final random inspection is self-evident. Through strict inspection, potential quality problems can be effectively discovered and solved, ensuring that the products shipped meet the requirements of customers and the market, thereby improving the market competitiveness and brand reputation of the products. Therefore, in the production process of cooler bags, enterprises must attach great importance to the implementation of final random inspection, continuously optimize inspection methods and standards, and ensure the continuous improvement of product quality.
In Chiterion bags, we carry out more strict internal inspection standards than the bag industry standards to ensure our customers can always receive qualified products.
Chiterion is committed to designing, manufacturing and supplying a wide range of ecological packaging products and solutions.
