(Summary description)Flexible plastic composite film material is an important part of pharmaceutical packaging. It can be used to package powder, granular, liquid and other types of drugs. Among the many performance indicators of flexible plastic packaging, the friction coefficient has an impact on the machine performance of the material and whether the packaging can be smooth. Proceeding has an important impact. If the dynamic friction of the packaging material is too large, the resistance generated during the traction process of the packaging material is relatively large, which may easily cause the material to be stretched and deformed, or even broken. If the static friction is too small, slipping is likely to occur during the traction process. For the formed flexible plastic packaging bag, the friction between the inner layer materials will also affect the opening of the packaging bag, and greater friction will cause The opening of the packaging bag deteriorates. Therefore, strengthening the test of the friction coefficient of the flexible plastic composite film material for medical packaging is an important guarantee for the smooth progress of the packaging process. The friction coefficients of the inner and outer surfaces of the same packaging material are not the same, and the friction coefficients of the same material on different contact surfaces are also different. Therefore, when testing the friction coefficient of flexible plastic packaging materials, you should specify the specific The friction surface and friction material.
