Contrary to popular belief, not all corrugated boxes are created alike. Granted, most look the same, brown paper board with rippled channels on the inside, but the quality of the board can vary, and that can affect what kind of labels will stick best to it. Racer Boxes has the inside track on this, because after manufacturing boxes for almost 20 years, it’s easy to tell what works best.
Many people use customized labels on their boxes. As a result, it’s important to make sure it will last until it reaches its destination. That means finding the right adhesive for a label, and knowing how that adhesive will work on a given type of corrugated box.
Taking a random sample of cardboard containers reveals a range in quality and construction. This is because they are typically made from recycled material, and how much recycled material is used can change from batch to batch (not to mention things like glue, ink, and other contaminants thrown into the mix). This can also affect how well an adhesive sticks when it comes to applying a label.
In addition, special treatments are sometimes applied when manufacturing cardboard, such as waterproofing or waxing on produce boxes, which can make the surface difficult to label. Aside from the initial application, a label is also going to be subjected to different environmental conditions, temperatures, and humidity on route.
Some common types of adhesives found on labels include rubber hot melt adhesives and acrylic adhesives. The former offers excellent initial tack, but can degrade and absorb contaminants, and do not handle high heat well. Acrylic, on the other hand, handle temperatures better, but might not perform as well in moist conditions. Taking this into consideration will go a long way to ensuring your labels stay on as intended.
