Packaging / Paper / Wood 

Materials like paper, wood, and cardboard are naturally hygroscopic — they absorb moisture from the air. That’s part of what makes them useful. But it’s also what makes them highly vulnerable during transport. When humidity rises inside the container and condensation forms, these products quickly degrade — either as input materials or finished goods.

This makes moisture control in the container environment not just smart — but essential. It’s not just about preserving boxes. It’s about protecting the quality of future packaging, components, or finished products.

Common products 

Corrugated boxes, paper rolls, packaging liners, wood pallets, MDF, fiberboard, raw lumber, printed packaging, wooden components 

Common damages and problems

Mould and mildew
Bad or changed smell
Warping of paper or wood
Collapsed or deformed packaging
Peeling labels
Softness

Our solutions 

The risk is built into the materials. Paper, fiber, and wood pull in moisture from the container air. If that moisture isn’t controlled — especially during long-distance sea freight — it leads to: 

  • Cartons losing shape or structure 
  • Warped or unusable input materials 
  • Musty smells or microbial growth 
  • Labels detaching or smudging 
  • Degraded visual quality or surface finish 

These issues affect not just the current shipment — but every product made with or packed in it. 

Absortech’s AbsorRange™, based on high-performance calcium chloride desiccants, reduces airborne moisture in the container and prevents condensation before it forms.

We recommend AbsorGel® Blanket or hanging, depending on cargo density and route complexity.
