Carton is the most widely used form of finished product packaging. In the process of product distribution, it can protect products and facilitate storage and transportation. Compared with wooden boxes, woven bags, plastic boxes and other packaging forms, cartons are easy to draw, light weight, small size, easy printing, easy production, low cost and so on.
The carton is usually a corrugated carton, and the space constructed by the corrugated wavy structure plays a good supporting and buffering role for the package. With the development of commodity economy, product packaging has become more and more sophisticated, and colored cartons have become more and more popular among merchants. In order to improve the quality of carton packaging, including physical properties such as carton strength and abrasion resistance and visual impact and other image quality, most color carton face papers will be coated with varnish or film. However, if the production process is not properly controlled, the problem of wrap-around cartons can easily occur. Not only is it not conducive to storage, it is not conducive to transportation, and even affects the display of goods in the market.
Analysis of carton fall causes:
The cartons appear to be down, and can be analyzed from the following points: First, the carton packaging design. Unreasonable packaging design If the contact area between the products is small or has a certain degree of inclination, it will cause the cartons to collapse; the second is the stacking height. Stacking too much will not only lead to pressure loss at the bottom of the goods, but also can easily collapse. Third, the coefficient of friction. If the coefficient of static friction of carton face paper is too small, friction between products may be small, and slight external force or misalignment will collapse. In view of this, when the carton packaging design is reasonable and the stacking height is appropriate, if the color printing cartons appear to fall, the static friction coefficient needs to be tested.
test instrument:
The MXD-02 friction coefficient meter of Jinan Languang Electromechanical Technology Co., Ltd. is a professional instrument for the friction coefficient test of paper and board. The instrument satisfies many test standards such as GB , ISO , ASTM, etc. The instrument test bench and the test slide are all subjected to degaussing treatment and residual magnetism detection, which can effectively reduce the system test error. Professional software can be used to automatically perform single piece and group The statistical analysis of the results of the experiment and the reanalysis of the original data and the superimposition of the group curves can quickly display the test results.

Test Methods:
Take the GB 10006-88 test as an example. Take the paperboard face-sheet paper and cut each of the three groups of 63 × 63 mm squares and 80 × 200 mm rectangular specimens. The test specimens should be flat, with no scratches that could change the rubbing properties, and no Dust and other foreign substances. A square sample was mounted on the bottom of the slide and the rectangular sample was mounted on the sample table. Set the test parameters, select the standard as GB 10006-88 , and start the test. At this point, the total system motion time is 42 s , where the static friction time defaults to 6 s and the dynamic friction time is 36 s . After the test, in the "test screen" display static friction coefficient and dynamic friction coefficient test results.
The coefficient of static friction can reflect the magnitude of the force that needs to be overcome when the carton face paper slides. If the static friction coefficient is too small, the carton can easily collapse, affecting the flow efficiency of products such as production, storage and transportation. Through the MXD-02 test, the static friction coefficient of the carton can be effectively judged, and carton dumping can be prevented and controlled in advance. On the other hand, the MXD-02 can also test the dynamic friction coefficient of the sample at the same time. The dynamic friction coefficient affects the carton production line. On the smooth flow. Therefore, if you need to test the smoothness of the cartons in the production line, you can follow this method.
