Controlling humidity in the packaging industry

Humidification and Moisture Control in the Packaging Industry
Humidity plays a vital role in packaging production. In supermarkets, thousands of packaged goods compete for attention, where packaging is key to protection, preservation, and visual appeal. Packaging producers aim for top quality and efficiency – and controlled humidity is a crucial factor.

Print Quality and Adhesion Depend on Proper RH
In printing, a stable humidity level of 50–55% RH ensures colour consistency, smooth paper handling, and prevents static electricity. For adhesives used on labels and cartons, proper humidity prevents drying and failure to stick – especially on glass or metal surfaces.

Preventing Static Electricity
When working with foil and plastic films, higher humidity is needed to neutralise static charges that can disrupt production. RH levels of 50–60% are often required depending on the material’s absorption.

Dimensional Stability in Board and Cardboard
For corrugated board and carton, the right humidity level prevents curling, surface damage, and print defects. Moisture control helps preserve flexibility and strength, reducing waste caused by cracks and visible white marks.

Efficient Post-Processing
During slitting and rewinding of label rolls, humidity at approx. 45% RH helps minimise static and ensures smooth operation.
