The quality inspection of cosmetic bag production mainly includes the following aspects:
1. Appearance quality inspection: including checking the overall appearance of the cosmetic bag, whether the stitch is neat, whether the zipper is smooth, and whether the printing is clear, to ensure that the appearance of the cosmetic bag meets the design requirements.
2. Dimensional accuracy test: including measuring the length, width, height, thickness and other dimensional data of the cosmetic bag to ensure that the dimensional accuracy of the cosmetic bag meets the design requirements.
3. Material quality inspection: including checking whether the materials used in the cosmetic bag meet the relevant standards, such as the strength, wear resistance, heat resistance and other properties of fabrics, zippers, buttons, flannelette and other materials.
4. Detection of stitch density: including checking whether the sewing stitch density of the cosmetic bag is uniform and whether the sewing thread head is firm to ensure that the sewing quality of the cosmetic bag meets the standard requirements.
5. Service life test: including testing the durability of the cosmetic bag under normal use, such as the durability of the zipper and the wear resistance of the fabric.
6. Environmental protection testing: including testing whether the materials used in the cosmetic bag are environmentally friendly, such as whether they contain harmful substances.
Through the above quality inspection, we can ensure that the quality of the cosmetic bag meets the standard requirements and meets the needs of consumers.
