雖然包裝紙箱有很好的性能，他們是相對脆弱的。一旦紙箱遇水，就會失去原來的性能。因此，很多廠家都會對紙箱進行防潮處理。如何對紙箱進行防潮處理?考慮到效果和成本，通常采用以下方法：
Although packaging cartons have good performance, they are relatively fragile. Once the carton meets water, it will lose its original performance. Therefore, many manufacturers will carry out moisture-proof treatment on cartons. How to damp proof the cartons? Considering the effect and cost, the following methods are usually adopted:
添加防水劑：一般情況下，廠商對紙箱的防潮處理是在紙箱外面涂一層防水劑。這種方法簡單，成本低。能給紙箱帶來良好的防潮效果，根據需要可分為臨時防水處理和長期防水處理。
Add waterproof agent: generally, the manufacturer's moisture-proof treatment for the carton is to apply a layer of waterproof agent on the outside of the carton. This method is simple and low cost. It can bring good moisture-proof effect to the carton. It can be divided into temporary waterproof treatment and long-term waterproof treatment according to needs.
覆膜工藝的使用：覆膜是紙箱面紙、紙箱、手袋、封面等印刷品常用的防水處理工藝。印刷品經層壓后可達到防水、防污、防褪色、耐熱、耐光、耐沖突的性能。這種處理不僅能給紙箱帶來優越的防水性能，而且能提高紙箱強度和抗拉強度的光澤度和撕裂度，提高紙箱的使用壽命和包裝質量。
Use of film coating process: film coating is a commonly used waterproof treatment process for printed materials such as carton paper, carton, handbag and cover. After lamination, the printed matter can achieve the performance of waterproof, antifouling, anti fading, heat resistance, light resistance and conflict resistance. This treatment can not only bring superior waterproof performance to the carton, but also improve the gloss and tear of the carton strength and tensile strength, and improve the service life and packaging quality of the carton.
添加高分子聚合物：目前在瓦楞紙箱的生產過程中，添加適量的高分子聚合物(又稱交聯劑或架橋劑)在淀粉粘合劑中，高分子聚合物將取代淀粉分子中的羥基，使瓦楞糊線具有較好的防水防潮效果。當紙箱進入冷庫或潮濕環境時，可防止瓦楞糊線吸濕乳化造成紙箱倒塌。
Add high molecular polymer: at present, in the production process of corrugated box, add an appropriate amount of high molecular polymer (also known as crosslinking agent or bridging agent) in the starch adhesive. The high molecular polymer will replace the hydroxyl group in the starch molecule, so that the corrugated paste line has a good waterproof and moisture-proof effect. When the carton enters the cold storage or humid environment, it can prevent the corrugated paste line from moisture absorption and emulsification, resulting in the collapse of the carton.
避免原材料受潮：如果紙箱的原材料在生產過程中已經受潮，會對后續加工生產的包裝紙箱產生很大影響。因此，大多數紙箱廠會盡量將原紙倉庫與外界隔離，保證相對溫度低，保障原紙質量。
The raw materials of cartons will be greatly affected if they are damp in the subsequent production process. Therefore, most carton factories will try to isolate the base paper warehouse from the outside world to ensure the relative low temperature and ensure the quality of base paper.
