FAQ's
Frequently Asked Questions (FAQs) – Coefficient of Friction (COF) Tester
What is a Coefficient of Friction (COF) Tester?
A Coefficient of Friction (COF) Tester is a laboratory instrument used to measure static and kinetic friction between two material surfaces. It helps packaging manufacturers control slip properties to ensure smooth machine operation and stable product stacking.
What does the MXD-02 Coefficient of Friction Tester measure?
The MXD-02 COF Tester measures:
Static COF – Force required to initiate sliding
Kinetic COF – Force required to maintain sliding
It is widely used for plastic films, laminates, paper, rubber, and flexible packaging materials.
How does the MXD-02 COF Tester work?
The MXD-02 operates on the horizontal plane method. A weighted sled is placed on the test material and pulled at a constant speed. The system records maximum and average force values to calculate static and kinetic coefficients of friction automatically.
What is the C620H Friction & Peel Tester used for?
The C620H Friction & Peel Tester performs both:
Coefficient of Friction testing
Peel strength testing
It evaluates slip characteristics and seal integrity in flexible packaging materials.
What is the difference between MXD-02 and C620H?
The MXD-02 is dedicated to static and kinetic friction measurement.
The C620H performs both friction testing and peel strength testing, making it ideal for laminated and heat-sealed packaging structures.
Which international standards do these testers comply with?
Both MXD-02 and C620H comply with international standards such as:
ASTM D1894
ISO 8295
TAPPI T815
TAPPI T816
This ensures accurate and globally accepted test results.
Why is friction testing important in packaging?
Friction testing prevents machine jamming, improves packaging line efficiency, and ensures stable stacking during storage and transport. Proper COF levels reduce production downtime and packaging defects.
Why is peel strength testing important?
Peel testing ensures proper heat seal strength and lamination bond integrity. It helps prevent delamination, leakage, and seal failure in food and pharmaceutical packaging.
What industries use MXD-02 and C620H testers?
These instruments are widely used in:
Flexible packaging industry
Plastic film manufacturing
Pharmaceutical packaging
FMCG packaging
Food packaging labs
Quality control and R&D laboratories
