Product quality is the foundation of a company's survival. Only by strictly controlling the quality of products such as container liners can a company guarantee its outstanding development. Inspection and distribution systems are effective means of controlling product quality.
1. Appearance Quality of Container Liners: Visual inspection.
2. Length of Container Liners: Measure the blank bag with a 1.0mm precision steel tape measure, parallel to the bag edge. Measure at three points and take the value with the largest standard error.
3. Width and ID Distance of Container Liners: Measure the blank bag with a 1.0mm precision steel tape measure, perpendicular to the bag edge. Measure at three points and take the value with the largest standard error.
4. Cutting and Slit Quality: Visual inspection.
5. Weight per Unit Area: Take a sample with a length of 10cm and a width of 10cm and weigh it using an electronic balance with an accuracy of 0.01g.
6. Printing color solidity: Rub the print with your thumb 3-5 times. If the amount of ink migration is small and the print is still clear, it indicates that the color is solid.
