Testing Adhesives Used in Glued Lap Joints of Corrugated Fiberboard Containers Useful Method UM 823 (2025)
This useful method describes processes for evaluating the adhesive used in glued lap joints of corrugated containers. To evaluate the strength of actual joints of finished boxes, one should use TAPPI T 813 “Tensile Test for the Manufacturer’s Joint of Fiberboard Shipping Containers.”
The procedures described here allow evaluation of heat resistance, water resistance, and cold resistance of the adhesive used in glued lap joints.
Not every adhesive formulation will require a given level of performance in each of these environments. One should select the applicable evaluation process(s) from this method based on the environmental conditions the container will be subjected to.
