A corrugated box is only as strong as the bond between its layers. You can buy the best kraft paper available, but if the adhesive does not set evenly or a belt slips on the double backer, the board warps, delaminates and fails the compression test.
Box plants buy two kinds of things from us: the raw materials that go into their adhesive, and the belts that carry board through the corrugator. On the adhesive side, maize starch is the base for most corrugation glue, and guar gum powder is used to adjust viscosity and tack. Plants that want stronger bonding in humid conditions also ask about urea formaldehyde additions.
Belts made for your machine
Our corrugator belts are made to the dimensions of your single facer or double backer, with heat-resistant construction for the hot plate section. For moving reels, bundles and finished boxes around the plant, we supply conveyor belts in the width, length and ply you need.
Where we help box makers
- Warp and delamination – consistent starch and well-matched belts for even pressure and bonding.
- Glue that is too thin or too thick – guar gum to control viscosity.
- Printing on boxes – coated liners from mills using our coating clay and whitening agents.
- Effluent from glue kitchens – flocculants and ETP chemicals.
Tell us your corrugator make, belt sizes and monthly starch use, and we will quote for both.
