Overview
Clay Coated (Kemi) White Board: Previously described as ‘deluxe white,’ Kemi White is a brand of white-top board, much like Band-Aid is a brand of bandages. The clay coated, white surface of this liner board offers premium printing quality, with a slightly glossy, smooth-finish, making it ideal for retail applications such as POP displays. Kemi board the only corrugated board that is clay coated and has a unique and distinct advantage for digital printing compared to mottled white. Thanks to the clay coated surface, inks are less likely to sink into the board, so the colors will pop and be more vibrant.

Corrugated Strength Tests
Edge Crush Test (ECT)
Force is applied perpendicular to the edge of the corrugated board until it buckles. The results provide accurate representation of the material’s strength, durability and stack resistance for heavier loads. The resulting value is shown in pounds per linear inch of load-bearing edge and is reported in ECT ratings.
Note: 32 ECT is the most commonly used for corrugated material.
Bursting Test
The burst test, otherwise known as the Mullen Test, challenges the durability of the corrugated fiberboard’s surface. The burst test determines the amount of force required to puncture the liner board. The resulting value is given in pounds per square inch.
Note: 200# means 200 pounds per square inch of force applied to the face of the liner board.
