Overview:
Our Water Absorption Test evaluates the amount of water absorbed by cardboard over a specified time, helping to determine its resistance to moisture exposure. This test is crucial for packaging materials that may encounter humid or wet environments during transportation or storage.

Test Description:
A sample of cardboard is cut to standard dimensions, weighed, and then submerged in water for a specified period (typically 5 minutes). After immersion, the sample is removed, surface water is gently wiped off, and the sample is weighed again. The increase in weight indicates the amount of water absorbed.

Purpose & Benefits:

• Assess moisture resistance of cardboard and packaging materials
• Predict product performance under humid or wet conditions
• Ensure material suitability for various environmental exposures
• Support quality control and material comparison
