Sustainable Void Fill Solutions

Void Fill is a paper filler material used to close up the free space in your shipping box.

What is Void Fill?

Void Fill is a paper filler material, used to close up the free space in your shipping box and lock products in place. When items are prevented from moving during transit, the chances of breakage go down. A paper-based filler offers excellent physical properties in terms of absorbing shocks and protecting sensitive products, and is also more sustainable than plastic alternatives.
