Cobb test is among the most essential physical property tests of paper. It is used to test the paper’s ability to resist the water penetration, plus the amount of water absorbed by the fiberboard surface. This test is performed due to the natural fact that the paper and fiberboard tend to catch water molecules present in the surroundings. It is because of this test that one can find if the paperboard is suitable for a particular packaging or not.
Why Cobb Sizing Tester Is A Valued Instrument
A cobb sizing tester is used to test this characteristic of paper. If the fiber or paper board is sent without being tested by this instrument, the paper’s ability to absorb water may not be known by the manufacturer. Let’s put this more simply. If the fiberboard absorbs more than normal water molecules from the environment, the box may find it challenging to stay strong and integrated. In this case, even the inside fluting can get detached from the outer liner, resulting in the breakage of the box. Now when the box breaks, the goods inside will naturally get damaged, and especially if it's a hazardous good, then you can easily imagine the outcome yourself.
Hence, it has become essential for the manufacturers to test their paper or fiberboard using the cobb sizing test machine, so that the right corrugated box can be used to deliver products to the customers.
Cobb Testing Is Easy
The cobb test gets handy when the manufacturers need to make sure that the products are packed in safe packaging. The water absorption tester is another instrument by UEC that tests the water absorbency of paper, specifically the blotting paper.
