 Cardboard
 Corrugated cardboard boxes are wax-coated with the aim of protecting their packing integrity, particularly for their application in the food industry, where products must arrive to the final customer without any harm in their essential properties. The systems most commonly used for wax application on corrugated cardboard boxes are the following:
- Cascade saturation.
- Saturation by immersion.
- Medium impregnation.
- Liner coating
The Cartowax® product line, developed and manufactured by Multiceras, is integrated by wax blends specifically formulated to improve the properties and characteristics of corrugated cardboard boxes. Fortified with special additive packages for each application system and use, the Cartowax® products provide excellent functionality and performance.
The properties of corrugated cardboard boxes, which are reinforced by applying Cartowax® products, are the following:
Humidity Resistance: Due to its protective nature, the Cartowax® products give the cardboard a greater protection against humidity, enabling the packed product to keep entirely its properties. Moreover, the Cartowax® application improves the strength and consistency of cardboard boxes, even when exposed to freezing temperatures for long periods of time.
Stowing Stiffness: Cartowax® increases the stiffness of corrugated cardboard boxes, improving their stowing capacity, thus leading to a more efficient and economic storage.
Lower Blocking Index: The higher blocking points of Cartowax® products decrease the blocking tendency of cardboard boxes during handling and storage.
Flexibility: The application of Cartowax® products improve the folding properties in the lines and marks of corrugated cardboard boxes.

Notes:
Melting point is determined in all cases by the USP 741 CLASS II method, with the exception of the 1546 wax, where ASTM D938 is used. Color is measured in all cases by ASTM D156. All applications are carried out on corrugated cardboard, with the exception of the 3016 wax that is utilized in the protection of egg trays.
