Friction of corrugated board ensures that boxes made from that board will not slip from a load. Some newer methods of material handling rely on a certain friction between the boxes, so it is important for the boxmaker or his linerboard supplier to control the amount of friction. The angle of inclination at which one box on top of another will just begin to slide is a measure of the coefficient of static friction between the two surfaces of the two boxes in contact. Derivation will show that the coefficient of friction is equal to the tangent of the angle of inclination from the horizontal. The coefficient, hence the angle itself, is independent of the force applied between the two surfaces. Therefore, the coefficient of friction or slide angle is not dependent on the weight of the box and its contents. The test covered in this technical information paper was devised to measure the coefficient between two box surfaces. It can also be used to measure the coefficient of friction between two paper surfaces prior to fabrication of the box. The test can be applied to linerboard before corrugating, to corrugated board after combining, and at any point up to and after box fabrication. Subsequent treatment, rubbing, or abrasion of that surface can alter the coefficient significantly. This is especially true if frictionizing materials have been applied to the surface. Subsequent processing could remove the frictionizing material, thereby lowering the coefficient. Reaffirmed 2002.

Control of the viscosity of a starch-based corrugating adhesive is critical to controlling the operation of the corrugating process and to obtaining good corrugator runnability. Viscosity that is too high will be difficult to pump, will not flow properly in the pan and will not adequately penetrate the linerboard and medium surfaces. Viscosity that is too low will not be picked up properly by the applicator rolls and will penetrate the linerboard and medium surfaces too quickly. To obtain a true picture of the state of control over the starch preparation and corrugating process, statistical process control techniques should be employed.

Caliper is an indirect measure of the compression stacking of corrugated boxes. Low caliper usually results in corrugated box performance below specifications. Caliper is maximized by (1) proper flute formation and bonding, and (2) minimizing crush after formation. The intent of this Technical Information Paper will be to discuss the benefits of SPC techniques and the application of these techniques to finishing machine crush. Discussion on box plant quality measurement TAPPI TIP 0304-02 Box Plant Quality Measurement: Why Test and corrugated box plant quality targets TAPPI TIP 0304-03 Corrugated Box Plant Quality Targets review questions and answers regarding quality and testing. TAPPI TIP 0304-04 Corrugated Caliper: Why Is It So Important details the importance of corrugated caliper in corrugated container construction.

Why is it important to measure and control corrugated board caliper This answer was published in TAPPI TIP 0304-04 Corrugated Caliper: Why Is It So Important and is reproduced in part as follows: Corrugated is a very popular packaging material primarily because it has a high strength-to-weight ratio. What this means is that corrugated is exceptionally strong considering its light weight. In fact, the primary job of a corrugated box is to protect its contents (i.e., our customers products). As such, corrugated should be considered to be an engineering material. It is amazing that we take several flexible pieces of paper and combine them into something very rigid. A 20 20 200-lb. test C-flute corrugated box can withstand almost 900 lbs. of weight before failing and yet it weight only 2.5 lbs. How can corrugated be that strong There are two reasons.
