3 Responsibilities and classification of product packaging inspection
3.1 The inspection department shall conduct various inspections and tests on product packaging in accordance with the provisions of this standard to ensure that the quality of product packaging meets the requirements of relevant standards or regulations.
3.2 Classification of inspection
Product packaging inspection is divided into type inspection and quality inspection. Type inspection is the inspection and test conducted to determine whether the product packaging quality and packaging design meet the requirements of relevant standards or contracts. Quality inspection is the inspection and test required for product packaging acceptance according to standards or packaging design specifications. It includes factory inspection, process inspection and factory inspection.
4 Type inspection
For newly designed product packaging, when there are major improvements and changes in packaging materials and packaging structures, as well as inspection of product production licenses and export commodity inspections, type inspection must be carried out, and all inspections and tests specified in this standard must be carried out on the various parameters and requirements of sample (prototype) packaging quality (see Table 1 to Table 3). After passing the test, the structure of the contents is intact, the accuracy and dimensional tolerance remain within the allowable value range (approved by the Ministry of Machinery Industry on October 25, 1994, implemented on October 1, 1995, JB/T7539-1994), and can be used. The packaging container has a reasonable structure, and the packaging materials, padding, and reinforcements are intact and maintain the predetermined protection capabilities. Prove that the product's protection, fixation and container functions meet the requirements for protecting the contents. Considering the characteristics and value of the contents of the package, simulated contents can be used for the test in Table 3. The size and physical properties of the simulated contents should be close to those of the predetermined contents, and the packages should be sealed according to the normal procedures before shipment. 5 Quality inspection
5.1 The quality inspection items and contents of product packaging (see Table 1 and Table 2) should include: a. Packaging material and packaging container inspection
All materials used for cleaning, protection and packaging must be inspected in accordance with the corresponding material standards or specifications to confirm that they meet the packaging design requirements of the product; packaging containers, accessories and accessories must be checked for their materials, sizes and weights according to packaging drawings and documents or relevant standards, and they can only be put into storage or used after they are confirmed to be qualified.
b. Protection inspection
Judge whether the protection methods, materials and containers used for the contents and their protective packaging meet the regulations. Rust-proof packaging should comply with GB4879. Moisture-proof packaging should comply with GB5048, mildew-proof packaging should comply with GB4768, and cushioning packaging should comply with GB8166. The contents and methods of inspection and testing shall be in accordance with the provisions of Table 1. For other protection methods other than those specified in Table 1, the requirements of the mandatory inspection items and contents specified in Table 1 shall be referred to according to their protection characteristics.
c. Product packaging inspection
Judge whether the quality, quantity, variety and documents of the contents are qualified and complete, whether the transport packaging is reasonable and reliable, and whether the packaging marks are complete, clear, standardized and beautiful, and comply with the provisions of GB/T13384, GB191 and relevant standards. The items of inspection and testing shall be in accordance with the provisions of Table 2 and Table 3. For specific requirements of inspection, please refer to Appendix A (reference). When the product standard or product packaging standard has inspection requirements that are consistent with this standard, the inspection can be carried out in accordance with the provisions of the product standard or product packaging standard. In order to avoid damage caused by inspection, large and medium-sized product packaging should strengthen process inspection. 5.2 Sampling inspection
Packaging delivered in batches shall be subject to sampling inspection as specified in GB2828. The composition of a batch, a batch should be composed of the same material, the same packaging method, the same variety, specifications, and the contents and packaging containers inspected at the same time, which can be regarded as all the packages manufactured in the same cycle. Samples (prototypes) must be randomly selected from each batch, the sample unit is a package, and the inspection level uses the general inspection level I. A single sampling plan is adopted, the average quality acceptance level AQL is 4%, and the sampling plan is determined according to the number of packages delivered for inspection. The determination of the sampling inspection plan can also refer to Appendix B (reference). 6 Inspection report
After the inspection is completed, an inspection report and inspection conclusion should be submitted. The content of the inspection report generally includes: a: Name, quantity, name of the inspected package; b. Name, specification, model, quantity and name and specification of the accessories of the contents; c. Type, structure, material, external dimensions and bundling status of the outer packaging; d. Protection method, protective material, support and fixing method of the inner packaging; e. Types of inspection, items and contents of inspection and testing, test instruments, equipment, methods, sampling inspection plans, etc.; f.Inspection results, with accompanying drawings and tables when necessary; 2
