Evaluating Coefficient of Friction in Plastic Films
In order to evaluate the stacking friction or resistance strength of plastic films, the Coefficient of friction testing is conducted. The poly films which are used for packaging purpose are very slippery in nature and are tend to slip over each other. This nature or property of plastic films is useful as they avoid the friction in between and avoid the loss of printing. But the friction or slipperiness must be up to a mark till which it is required. For instance, if two packets are too slippery then they will slip down from storage place and during transport loading and will fall and burst. Leading to content wastage. And if it is not slippery then it will in the influence of external force because friction and can damage the cover or colour of the packets. In this post, we will read more about the role of Coefficient of friction tester.
In this test, one has to take care of many points. These points are important to keep in kind for getting bets testing results. If there is any dust or any other particle on the surface of the testing sample, please remove it. It can lead to faulty test results. Anything which is there which can contribute towards the rise or fall of friction should be removed. The ASTM D 1894 testing standards must be followed. It is considered to be the best for friction testing.
Presto Stantest, one of the leading manufacturers and suppliers of the testing instrument is the proud supplier of Coefficient of friction tester.
It helps in performing accurate friction test on poly films and ensure high-quality products. The sliding friction of the packing material can be easily estimated using the machine. The factors which are responsible for packaging damage is generated from the faulty friction quality of packets. Therefore it is very important for manufacturers to conduct the testing of friction materials prior to its use in production.
