    Paper & Board

    Notwithstanding the above, a sample size shall be Full Reel Size in a length of 100/50 cm

    Box

    Available actual size / Nearest to Sample Size as specified.

    Viscosity of Adhesive

    This is critical in assessing its bonding strength.

    Caliper

    Another major to amount of pulp that goes into one unit area of paper. It is a useful benchmark.

    pH Value

    This is significant for adhesive as well as ink compatibility with paper and hence, useful major for convertors.

    Tear Factor

    A measure of how easy or difficult it is to tear the paper after the initial has occurred. This property has relevance to the puncture resistance of converted board.

    Substance

    Substance, Grammage or basis weight is an important parameter for comparison purpose. It is an indication of the amount of pulp that goes into forming one unit area of the paper. Its importance is brought to fore when comparing the other test results. It is a useful benchmark.

    Burst Factor

    Bursting strength is the most widely used strength parameter for kraft paper. It is believed to be indicative of the resistance of paper of Bursting Forces found in transit or in storage. Burst Factor equals Bursting Strength divided by Grammage. Thus, Burst Factor or "BF" is a useful indicator of strength property regardless of substance.

    Tensile Strength and Breaking Length

    Tensile Strength is the force per unit width parallel to the plane of the sheet that is required to produce failure in a specimen of specified width and length under specified condition of loading. The strength of the paper is also expressed in terms of breaking length, i.e. a length pf paper that can be supported by one end without breaking.

    Cobb Value

    A measure of how much water the paper will absorb in given time, say, one minute. This property has relevance to adhesive pick up during converting as also extent of loss of strength due to high humidity.

    Moisture

    Strength properties of kraft paper are directly related to moisture levels in the paper / board. Generally, higher the moisture level, lower the strength.

    Ring Crush

    Ring Crush of kraft paper is indicative of how much edge crush and then, how much compression strength to expect from converted board. This is one of the most important areas where the data is non existent.

    Concora Medium Test (CMT)

    Evaluates the ability of corrugating medium to contribute the compression strength of corrugated box.

    Flat Crush Test

    Flat Crush Test of Corrugated Fibre Board ia a measure of the resistance of the flutes in a corrugated board to a crushing force applied perpendicular to the surface of the board.

    Puncture Resistance

    Reflects the strength of paper as well as converting efficiencies. It is more relevant in case of 5-ply and 7-ply. It correlates better with the resistance of corrugated boards ot external forces.

    Edge Crush Value

    Edge Crush Value of corrugated board gives an indication Box Compression Strength. Thus, it is an important test property of corrugated board to check during box manufacturing.

    Box Compression Strength

    This is replacing Bursting Strength as the most important test for corrugated boxes. As the stacking height increases and automated handling replaces manual method, Compression Strength becomes more relevant.

    Corrosion of Stitching Wires

    Rusted pins are not acceptable for aesthetic reasons, especially where box has multi-colour printing, and for hygienic reasons where boxes are used to pack food items. This test indicates the level of resistance to corrosion.
