What is a Rub Resistance Tester (Scuff Tester) used for?

A Rub Resistance Tester is a laboratory instrument used to evaluate print durability, ink bonding strength, and color transfer resistance on packaging materials like paper, boards, corrugated boxes, plastic films, and aluminum foils by simulating real-world handling and transit friction.

What pressure and speed does the Vertex Scuff Tester operate on?

The instrument applies a uniform pressure of 2 p.s.i (with separate weights available for 2psi & 4psi) at a steady speed of 60 RPM between identical substrate samples.

What are the specimen size dimensions supported by this machine?

The Rub Resistance Tester supports specimen sizes of 2 inches and 4.5 inches in diameter.

How is the cycle count controlled during testing?

It features a digital preset cycle counter with a testing capacity ranging from 0 to 9,999 cycles for automated and precise operation.

What are the electrical power requirements for this equipment?

The machine operates on an input power supply of 230 Volts, 50/60Hz, single-phase, with low power consumption of under 100W.

Why is testing rub resistance important for packaging materials?

Higher rub resistance signifies superior ink bonding and print quality. It ensures that printed text, logos, and designs on packaging do not smudge, bleed, or degrade during shipping, warehousing, and handling.

Product Overview

Our Rub Resistance Tester is a precision-engineered laboratory apparatus engineered to measure the abrasion and scuff proofness of printed or coated surfaces on paper and boards. By rubbing two identical samples against each other in the same plane under strict mechanical parameters, the equipment detects potential color bleeding and surface degradation. A higher rub resistance value signifies premium ink bonding and superior print quality across different manufacturing batches and suppliers.
