Friction coefficient is a crucial factor in the packaging process, affecting both drag and resistance forces.
This study utilizes a Labthink C620H Friction / Peel Tester to measure the coefficient of static and kinetic friction for two representative materials: PC film and aluminum foil complex film. The tests were conducted at varying temperatures ranging from room temperature to 90.0 °C.
Tested Materials include a PC film, which is a common type of plastic film used in packaging applications, and an Aluminum foil complex film, this film combines aluminum foil with another material, likely plastic, to offer specific properties like barrier protection.
Labthink C620H Friction / Peel Tester is utilized in this study. This instrument measures coefficient of static and kinetic friction of plastic films, sheets, foils, paper, and many other materials, it can also measure the peel strength of adhesive laminated products, medical adhesive bandage, release paper and protection films.
The test result revealed that temperature has a significant influence on the friction coefficient of both films. However, the effect varied between the materials and between the static and kinetic coefficients for the same material. PC film exhibited a steady increase in the static friction coefficient with rising temperature. The kinetic friction coefficient also increased overall but demonstrated a more significant variation compared to the static coefficient. Aluminum foil complex film displayed a less pronounced rise in friction coefficient compared to PC film. Notably, the kinetic friction coefficient for aluminum foil remained relatively stable throughout the temperature range.
In Conclusion, selecting packaging materials needs to consider temperature's influence on friction coefficient. Material properties like stiffness, smoothness, and the presence of additives also play a role. It's crucial to test the friction coefficient under realistic operating temperatures, not just at room temperature, to ensure optimal packaging performance. The Labthink C620H Friction / Peel Tester offers a valuable tool for conducting these tests and controlling friction coefficient within the desired range for successful packaging operations.
As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
