IDM Instruments Pty Ltd

A Cobb Absorption Tester measures how much moisture paper and packaging materials absorb over a set time.
Helping manufacturers verify water resistance before packaging failures happen.
For industries like:
• Packaging & Paper
• Corrugated Board
• Printing & Converting
Excess water absorption can lead to:
• Warped cartons
• Reduced board strength
• Print quality issues
• Adhesive failure
• Shortened shelf life
If you’re a:
• Quality Manager
• Packaging Engineer
• Production Supervisor
• Lab Technician
IDM Cobb Water Absorption Test helps measure how much moisture water and board absorb under controlled conditions.
Using standards like:
• ISO 535
• TAPPI T 441
• AS1301.411
• ASTM 3285
Manufacturers can improve:
✔ Moisture resistance
✔ Packaging consistency
✔ Product quality control
✔ Customer confidence
Because once packaging absorbs moisture, performance drops fast.
