Kemi White Board

Kemi White Board features a semi-gloss-coated brilliant white C1S linerboard on one side, perfect for high-quality printing and finishing capabilities. In addition, this material has a semi-gloss coating pre-applied making your prints require no additional coatings to get a semi-gloss finish. However, Kemi is more expensive than its mottled white counterpart.

  • Brilliant semi-gloss coated white surface
  • Printed colors appear more vibrant
  • More expensive than mottled white
  • 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

    flute grades

    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.

    Box Maker Certification

    The Box Maker’s Certification seal is usually printed on the bottom of a box and indicates how well your corrugated box did in the quality control testing process. Although not legally required, these seals act as a form of proof that the box has been properly tested and rated.
