Introduction

Why is humidity control important to Print & Packaging?

Print & packaging facilities require an optimal relative humidity between 50-60%. Dry air can cause paper curl, web breaks and static build up. When spooling paper, printing presses generate electrostatic charges which then cause the pages to become difficult to separate.

Humidity control helps to stabilise the conditions, dimensional stability of paper and other hygroscopic materials is improved and therefore paper jams and machine breakdowns are unlikely to occur. Machinery will be able to work at higher speeds resulting in an increase in product quality, production, and profits.

Specifically for packaging where plastics and glue are used then humidity control helps with preventing static and reducing curing times.

Benefits

Adiabatic humidifiers spray a fine mist that absorbs heat as it evaporates. This cools the air naturally, taking the pressure off your air conditioning system and reducing your electricity costs.

Paper and packaging materials are highly hygroscopic, meaning they readily absorb and release moisture as relative humidity changes. Maintaining a stable 50–60% relative humidity helps prevent paper curl, dimensional changes, web breaks, and static-related issues. This significantly reduces paper jams, machine stoppages, and unplanned downtime, helping production lines run at maximum speed while improving your site's profitability.

Rapidly moving paper, board and plastic films generate electrostatic charges that can cause sheets to cling together, leading to feeding problems and production delays. Maintaining the correct relative humidity helps dissipate static build-up, improving sheet separation and feeding reliability, while also optimising the performance and curing of industrial adhesives and laminates.
