A method to produce paperboard with a lightweight low-density coating, TAPPI Journal November 2025
ABSTRACT: In this work, a method is described in which a coating layer is produced that consists of a network of bubble-shaped air-filled voids within the coating. This is accomplished by instantaneously flash-drying all the water in the coating as it exits the application nip. The nip is formed between a polished chrome drum and a deformable press roll. The combination of the drum temperature, nip pressure, and nip width allow for sufficient energy to be transferred to the coating to completely flash-dry the coating material. The pressure within the nip is sufficient to allow the coating to superheat within the nip, then flash boil as it exits the nip. This boiling effect and resulting expansion are constrained by the roll surface, resulting in a coated surface that mirrors the polished chrome surface. The coating immobilizes while in the process of boiling, which preserves the bubble structure. With a coat weight of 5 g/m2, a flat, smooth surface is produced. This process was scaled up to a mill production machine layout and run at speeds as high as 450 m/min.
Editorial: The U.S. pulp & paper industry at a crossroads: Can it lead the bioeconomy
The industry is entering a pivotal moment in which many of us find ourselves engaged in deep soul searching. Since the days of Francis Bacon when the illustrious triumvirate of gunpowder, the compass, and paper were the drivers of civilizations, our community has enjoyed a noble place at the table. Indeed, especially over the last 100 years, pulp and paper has quietly powered communication, commerce, and, more than ever today, packaging, thus representing a steady backbone for the continued stability of many global industries.

5 Trends Changing the Future of Corrugated Packaging
The global corrugated packaging market is growing faster than expected, confounding some predictions that forecast a slowdown in corrugated consumption, although recently grounded expectations are not as bullish as some fringe predictions circa mid-2018. A downturn in demand in China and the banning of contaminated recycled paper stocks has not fully materialized yet, either.
