Edge boards, also known as paper corner protectors, are one of the popular packaging products internationally, serving as an alternative to wooden packaging and other bulky packaging methods. They offer advantages such as lightweight, durability, environmental compliance, and affordability, making them highly favored. When it comes to the moisture resistance of paper corner protectors, how can we improve their moisture resistance? Let the paper corner protector manufacturer elaborate on this next!

To enhance the moisture resistance of paper corner protection packaging, it is generally done by applying a beeswax blend coating or immersing in strong paperboard, among other methods. However, due to varying requirements for the surface coverage quality of the inside and outside of the paper corner protection packaging, different beeswax blend coating techniques must also be employed.

The pulpboard stream is achieved either by immersing the board into a槽 filled with a molten mixture of agents or by passing the liquid mixture through the vertical corrugations of the fluted paperboard. For thicker coatings, the molten mixture is applied by moving a perforated nozzle over the board sheets.
