Overview
The Cobb Sizing Tester – Tilting Type by QGI (Quantum Global Incorporation) Is A Precision Laboratory Instrument Used To Determine The Water Absorption (Cobb Value) Of Paper, Paperboard, And Corrugated Board.
Designed As Per ISO 535, TAPPI T441, and Related International Standards, This Tester Helps Manufacturers Evaluate The Sizing Quality, Water Resistance, And Surface Absorption Properties Of Paper Materials.
What Is Cobb Value?
Cobb Value Represents The Amount Of Water Absorbed By Paper In A Specific Time (Usually 60 Seconds) Under Standardized Conditions. It Is Expressed In G/M² And Is Critical For:
Printing Quality
Packaging Durability
Ink Performance
Moisture Resistance
