GM-4 - Coefficient of Friction Tester for Packaging Film

---

The GM-4 Coefficient of Friction (COF) Tester from GBPI is used to evaluate the smoothness, uniformity, and sealing performance of plastic films, paper, and other packaging materials in industries such as packaging, membrane production, and quality inspection laboratories.

 

It is a high-precision instrument designed to measure both static and kinetic (dynamic) friction coefficients, as well as the sliding behavior of plastic films, composite materials, aluminum foil, paper, and other packaging substrates. This helps ensure stable material handling and optimal processing performance during production.

 

Key Features and Applications

 

• Standards Compliance:
  Fully complies with international standards such as ASTM D1894, ISO 8295, and relevant GB standards.

 

• Tested Materials:
  Flexible packaging films, sheets, rubber, ceramics, and other related materials.

 

• Functions:
  Measures static and kinetic friction (COF) to ensure efficient packaging machine operation and stable stacking performance.

 

• Industries:
  Widely used in packaging industry, film manufacturers, and quality control laboratories.

 

• Advantages:
  High precision, easy operation, and essential for optimizing production processes and improving final product quality.

 

The GM-4 tester plays a key role in ensuring packaging performance consistency, helping manufacturers maintain product reliability and production efficiency.
