Wax Coated Cardboard Boxes for Food & Shipping | Durable, Moisture-Resistant

Wax coated cardboard boxes are packaging solutions that combine the structural strength of cardboard with the waterproof and oil resistant properties of a food grade wax coating. The base material is high quality kraft cardboard or white cardboard, selected for its rigidity and ability to withstand stacking during transportation. The wax coating—applied via either spray coating or dip coating processes—is typically food safe paraffin wax or microcrystalline wax, which forms a uniform barrier across the cardboard surface. This barrier prevents liquids, oils, and moisture from penetrating the cardboard, avoiding warping, tearing, or content contamination. These boxes comply with global safety standards, including FDA 21 CFR Part 172.886 for food contact and EU 10/2011, ensuring they are safe for use with food products ranging from fresh produce to baked goods. Design features include pre scored folds for easy assembly, tuck top or flap closures for secure sealing, and optional handles for convenient carrying. Sizes vary widely, from small 10x10x5 cm boxes for individual pastries to large 40x30x20 cm boxes for bulk produce or multiple food items. Some designs incorporate ventilation holes for products that require air circulation, such as fresh bread or fruits, without compromising the wax barrier. Application scenarios: in grocery stores, they package fresh fish or meat, preventing blood and juices from leaking; in bakeries, they hold large loaves of bread, protecting them from moisture while allowing slight air flow; in catering services, they transport prepared meals like pasta or salads, resisting sauce spills. A notable case is a seafood market that switched to wax coated cardboard boxes for packaging fresh salmon. The wax barrier contained fish juices, keeping the boxes dry and clean, and reduced the need for additional plastic liners, cutting packaging waste by 20%. Another example is a catering company that used the boxes for delivering hot lasagna— the wax coating resisted tomato sauce leaks, and the cardboard structure maintained its shape even when holding hot food, improving delivery efficiency. For businesses seeking durable, protective packaging for moisture or oil prone products, wax coated cardboard boxes balance functionality and sustainability.
