Packaging School and AICC on Strengthening Corrugated Packaging Against Cold-Weather Conditions

Our very own Dr. Suggs and Alli Keigley write in a feature of BoxScore by AICC.

Dr. Suggs states:

"Cold weather doesn’t have to crush your corrugated game. Keeping packaging strong in winter starts with climate control: Store and convert corrugated materials in heated areas (above 55 degrees Fahrenheit) to prevent brittleness and adhesive failure. Avoid unconditioned storage spaces, especially near loading docks or drafty zones, where boxes can absorb excess moisture or become frozen. Applying moisture-resistant coatings, using wet-strength liners, and adding desiccants can also guard against high humidity, which drastically reduces stacking strength. For extra protection, boxes can be engineered with stronger flute profiles or double-walled designs to boost performance in cold-chain logistics.

Corrugated manufacturers play a crucial role in fortifying packaging against winter’s harsh effects. By carefully selecting raw materials and enhancing the board’s construction, they boost moisture resistance and cold tolerance. For example, companies like Smurfit WestRock and International Paper use wet-strength resins and higher-quality fibers to help maintain structural integrity in damp or freezing conditions. Many producers offer specially engineered liners and flute profiles designed to improve stacking strength and durability during cold-chain transport. Additionally, surface coatings and barrier treatments reduce moisture absorption, while tailored adhesive formulas ensure strong bonds even at low temperatures. Through these innovations, corrugated companies help ensure that packaging thrives in the cold."
