Boxes that hold up more,
losses that stop
Some corrugators lose contracts because their boxes can't handle moisture, grease, or transport. Others have already solved that — with water-based coatings that protect the structure, keep the Cobb low, and survive the cold chain. These are their solutions.
Water-Based Coatings
Recyclable, repulpable, and compatible with your current processes.
Flexible Application
Wet end, dry end, off-line, or flexo — wherever you already work.
With Coaterex, your corrugator can:
More technical value for your customers. More margin for you. Without changing the industrial logic of your operation.
Eliminate plastic and paraffin
Migrate to repulpable water-based systems that comply with current and upcoming regulations.
Guarantee convertibility
Controlled printability and joint/flap bonding that doesn't fail at the customer's plant.
Withstand the real logistics chain
Moisture, abrasion, stacking, and ocean freight: the conditions your packaging must survive.
Win customers with differentiated proposals
Food, agriculture, consumer goods, and industrial: specific solutions other corrugators don't offer.
The exact protection your customer needs
Each application has its own technical route. Here are the most common ones in corrugators — with recommended coatings and the criteria that determine which to use.
How to choose the right coating without scaling risk
Before committing to full production, validate these points. Corrugators who follow them have no surprises — not in the plant, not with their customers.
Recommended test methods
COBB (2 minutes)
Measures liquid water absorption in paper/board.
MVTR (ASTM E96)
Evaluates moisture vapor transmission.
3M Kit (Oil & Grease)
Determines grease and oil resistance.
Sutherland / COF
Controls abrasion behavior and non-skid performance.
Define substrate, use conditions, and functional priority: water, grease, moisture, rub, or release.
Select application method and point: wet end, dry end, off-line, or flexo.
Evaluate impact on printability, drying, and corrugator speed.
Confirm regulatory requirements if applicable: FDA, BfR, EU regulation.
Validate bonding with cold-set and/or hot-melt at your plant and the customer's.
Run a pilot trial to tune coat weight and adhesive before full production.
