The coefficient of friction is actually a house vital for the optimum processing and handling of packaging from filling operations by way of towards the customer. COF is defined because the force essential to move 1 surface more than one more, divided by the total force applied typically to these surfaces. The values are among zero and one particular and are dimensionless. You can find two typical standard COF tester machines - sliding plane and incline plane.
Why does it matter? When the static COF is also higher, complications with the stacking and unstacking of cartons, boxes, and sacks will take place. Versatile films might bind when sliding onto filling collars. If static COF is as well low, difficulties in keeping stability in stacks could outcome, at the same time as difficulty pulling components via automatic processing machinery.
If kinetic COF is as well high, this could result in hang-ups along packaging lines, undue folds, erratic net tensions, and buildup of static electrical energy. When the kinetic COF is also low, guide rolls may possibly not rotate, tracking along the production line becomes irregular, internet tensions once more may well be erratic, along with the material will run eccentrically.
Acquiring the COF correct by way of COF the testing machine is largely a method of qualifying a packaging item and after that supplying this solution at a constant COF specification primarily based on an offered instrument and testing procedures. Be conscious that diverse COF testing machines and procedures have a poor correlation.
Most Commonly Used COF Testing Machines
C620H Friction / Peel Tester
C620H Friction / Peel Tester is usually applied to test the coefficient of static and kinetic friction of plastic films, sheets, foils, paper, cardboard, woven bags, fabric (fabric style test), metal-plastic composite strip/belt for communication cable, convey belt and textile, also as peel strength test of adhesive laminated merchandise, healthcare adhesive bandage, release paper and protection films.
MXD-02 Coefficient of Friction Tester
MXD-02 Coefficient of Friction Tester is applicable for the determination of static and kinetic coefficient of the friction of plastic films, sheets, rubber, paper, PP woven bags, fabric style, metal-plastic composite strips/belts for communication cable, conveyor belts, wood, and coatings.
FPT-F1 Friction/ Peel Tester
FPT-F1 Friction/Peel Tester could be utilized to measure the coefficient of static and kinetic friction of plastic films, sheets, foils, paper, cardboard, PP woven bags, fabric( fabric style test), metal-plastic composite strip/belt for communication cable, convey belt and textiles, too as peel strength test of adhesive laminated items, healthcare adhesive bandage, release paper, protection films, and so forth.
COF-P01 Inclined Surface Coefficient of Friction Tester
COF-P01 Inclined Surface Coefficient of Friction Tester could be employed for the coefficient of friction tests for paper, cardboard, plastic films, sheets, and conveyor belt and so forth. By the smoothness measurement, it could be utilized to adjust the open easiness of pouches, packaging speed of packing machine along with other excellent indexes so as to meet the application demands.
