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(duì)紙箱的防潮處理是在紙箱外面涂一層防水劑。這種方法簡(jiǎn)單，成本低。能給紙箱帶來(lái)良好的防潮效果，根據(jù)需要可分為臨時(shí)防水處理和長(zhǎng)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(jīng)層壓后可達(dá)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(lái)優(yōu)越的防水性能，而且能提高紙箱強(qiáng)度和抗拉強(qiáng)度的光澤度和撕裂度，提高紙箱的使用壽命和包裝質(zhì)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(chǎn)過(guò)程中，添加適量的高分子聚合物(又稱交聯(lián)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(dāng)紙箱進(jìn)入冷庫(kù)或潮濕環(huán)境時(shí)，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(chǎn)過(guò)程中已經(jīng)受潮，會(huì)對(duì)后續(xù)加工生產(chǎn)的包裝紙箱產(chǎn)生很大影響。因此，大多數(shù)紙箱廠會(huì)盡量將原紙倉(cāng)庫(kù)與外界隔離，保證相對(duì)溫度低，保障原紙質(zhì)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.
