This article is provided by Jinan Zhuyan Instrument and Equipment, the friction coefficient peel tester ATF-10 (also known as the friction coefficient tester), in line with the domestic test standard for the friction coefficient of flexible plastic packaging GB 10006-1988 "Plastic Film and Sheet Friction Coefficient Determination Method". This test equipment is widely used in the dynamic and static friction coefficient testing of plastic films, foils, paper, cardboard, woven bags, fabrics, metal material composite belts, conveyor belts, textiles, papermaking and other materials for communication cables and optical cables, and is also suitable for peel strength testing of adhesive composite products, medical patches, release papers, protective films and other products.
Friction coefficient tester is a method for testing the slippery performance of cigarette film in a high-temperature environment. In the process of cigarette packaging, the smoothness of the soft plastic cigarette film for packaging has a crucial impact on the operation and packaging speed of the packaging machine. This article will describe in detail the basic process of friction coefficient testing and the testing instruments used, hoping to help you when choosing the testing instruments and testing methods for the slip performance of flexible plastic packaging.
The soft plastic cigarette film on the outside of the cigarette cartridge is mostly biaxially oriented polypropylene film (BOPP), which has excellent transparency, gloss, shrinkage, moisture resistance and fragrance retention.
As an important performance index of cigarette film, the wear coefficient directly affects the speed of cigarette packaging, the stable operation of the packaging machine and the packaging effect. At the same time, the wear coefficient also involves the friction coefficient between the inner and outer surfaces of the packaging film and the cigarette pack carton, generally speaking, the friction coefficient of the outer surface of the cigarette film should be low, and the friction coefficient of the inner surface should be high.
One factor that has a great influence on the friction coefficient of flexible plastic packaging is the temperature of the packaging film. In the actual production of cigarette factories, the friction between the inner and outer surfaces of the packaging film and the cigarette pack carton is carried out at room temperature. However, during the operation of packaging equipment, the temperature of equipment components is often higher than room temperature, so the coefficient of friction generated when the packaging film slides on the equipment is very different from the coefficient of friction at room temperature.

Coefficient of friction Peel Tester ATF-10
Friction coefficient tester to detect the slip performance of cigarette film in a high temperature environment, method operation steps.
1) According to the longitudinal uniform cutting of the sample 6There are 6 samples in 35 cm 10 cm and 25 cm 13 cm, and one piece is selected from each specification, with a total of 3 groups of samples.
2) Select the friction coefficient test mode, and set the test speed, test temperature, stroke and other parameters.
3) Place 6The 35 cm 10 cm cigarette film specimen is clamped onto the slide to ensure that the inner surface of the sample is in direct contact with the slideWhen the test bench reaches a predetermined temperature, the 25 cm 13 cm specimen is flattened on the test bench and stabilized with tape or specimen fixtures, with the outer surface of the specimen facing upwards. In this way, a system for testing the coefficient of friction between the outer surfaces of the specimen is constructed. Note that the hand should not touch the test surface of the specimen during specimen clamping, and ensure that the specimen is flat and wrinkle-free.
4) Connect the slide to the force sensor with the help of a connecting device, and then gently place the slide on the specimen** fixed on the test bench so that the glide direction of the specimen is parallel to the direction of its test.
5) Tap the Start option to start the experiment. The machine automatically calculates the coefficient of friction based on the change in force value during the test and displays the test result.
In general, the friction coefficient peel tester ATF-10 can not only be used to test the dynamic and static friction coefficient of cigarette film, but also meet the testing needs of the peel strength of medical patches, release liners and other samples. At the same time, the equipment is easy to operate, the test results are highly accurate, and the repeatability is excellent.
