Cobb testing is a water absorption study that places a quantitative number (g/m2) on teh amount of water absorbed into a material over a specific amount of time.  All testing done adheres to strict Tappi Standard - T441 protocol.  The lower the number, the better the ability to repel water.

As you can see from this chart, the Genpak Harvest Fiber plate performed 42% better than the similar Primeware plate and 196% better than the similar Chinet plate.

What this means is you can expect better product performance when using Genpak Harvest Fiber products.
