Many labels are made of plastic rather than paper, but it is rare for cartons to be made of plastic. Therefore, achieving waterproof functionality is challenging, especially while meeting environmental or plastic reduction requirements. We recommend printing a waterproof coating on the surface of the cartons, which avoids the problem of adding plastic materials through protective films.
By applying a layer of water-repellent agent to the outside of the carton, it can withstand rain without becoming soggy and breaking apart! Compared to laminated cartons, this approach is more environmentally friendly! For food delivery, frozen shipping, waterproofing against rain... this type of carton is definitely the best choice!
Waterproof Principle of Frozen Cartons
The biggest culprit causing cartons to become soggy with frozen goods is the moisture in the air, which condenses into water droplets when it comes into contact with the cold carton. However, the moisture inside the carton is relatively low. As long as it is properly sealed and a waterproof coating is printed on the outside of the carton, it can stay dry!
Precautions for Frozen Carton Packaging
The moisture inside the carton is actually very minimal, and the carton can absorb it. However, if the products have accumulated a thick layer of frost before being packed, the melted frost will still wet the carton. Therefore, it's best to clean off most of the frost before packing, or pack the items first and then freeze them, to avoid any issues!
VOID Security Sealing Tape
Frozen cartons have a water-repellent coating, making them smoother, but they still work well with "VOID Security Sealing Tape." The usage is similar to regular packing tape, but when the tape is peeled off, it leaves a "VOID OPEN" mark on the carton. This ensures that the product has not been tampered with before reaching the customer, preventing content loss or disputes between buyers and sellers, and conveying care and integrity from a distance!
Waterproof Labels for Freezing
If products need to be stored frozen, they will require low-temperature and waterproof labels. For detailed information, please see this article: High (Low) Temperature Resistant Labels | Freezer Labels | Waterproof Labels
