1.建議改用防水防潮效果更好的原紙，特別是起坑的瓦紙。檢驗原紙的防水效果如何，可通過可勃儀測試原紙的表面吸水性，一般表面吸水度在50克/平米（60S）以下時，防水防潮效果較好。通常，造紙廠為了提高原紙表面防水性，在造紙工藝中需要提高表面施膠淀粉糊液中防水助劑的比例。
1. It is suggested to use the base paper with better waterproof and moisture-proof effect, especially the tile paper with pit. In order to test the waterproof effect of base paper, the surface water absorption of base paper can be tested by the Cobb instrument. Generally, when the surface water absorption is below 50g / m2 (60s), the waterproof and moisture-proof effect is better. Generally, in order to improve the surface waterproof property of base paper, the proportion of waterproof additives in the surface sizing starch paste solution should be increased in the papermaking process.
2.在紙箱生產加工過程中，應盡量去除紙箱內的水份。原紙倉庫盡量與室外隔絕，避免倉庫內部空氣潮濕。制糊時增加粉的含量，減少上膠量，可減少紙箱的水份。另外增加硼砂比例也會改善瓦楞紙板的手感。減少過紙天橋的紙板堆積量，放慢車速，特別是瓦楞紙板堆疊后進行充分抽濕。
2. During the production and processing of cartons, the moisture in cartons should be removed as much as possible. The base paper warehouse should be isolated from the outside as far as possible to avoid the humidity inside the warehouse. When making paste, increase the content of powder, reduce the amount of glue, can reduce the moisture of the carton. In addition, increasing the borax ratio can also improve the feel of corrugated board. Reduce the stacking amount of paperboard across the paper overpass, slow down the speed, especially fully dehumidification after stacking corrugated paperboard.
3.儲存環境，下線后的紙板應該在抽掉尚未散掉的蒸氣，避免溫差形成凝水現象，儲存紙板或紙箱的環境保持通風透氣，紙板紙箱避免放在地面，采用墊板（托盤、夾板）承起。存放中注意相互間的間隙，以利于通風散熱。
3. Storage environment: the off-line cardboard should be drained of the steam that has not been dispersed to avoid condensation caused by temperature difference. The environment for storing cardboard or cartons should be kept ventilated. The cardboard boxes should not be placed on the ground and should be supported by base plates (pallets and splints). Pay attention to the space between each other during storage to facilitate ventilation and heat dissipation.
4.在產品交貨過程中，有的使用敞篷貨車運輸，有的使用廂式貨車。通常后者比前者更能保護紙板紙板的干燥，避免及減少回軟。
4. In the process of product delivery, some use open truck transportation, some use van. Generally, the latter can protect the drying of paperboard better than the former, avoid and reduce the softening.
5.瓦楞紙板從紙板流水線下線之后應盡快進入下道工序，周期越長，紙板發揮容易吸收空氣中的水份而回軟。要盡量縮短紙箱在生產加工過程中的停留時間，避免暴露在潮濕空氣中的時間過長而回軟。車間也應該與室外進行適度隔離，避免水汽直接吹進車間。
5. The corrugated board should enter the next process as soon as possible after it is offline from the paperboard assembly line. The longer the cycle is, the easier the paperboard will absorb the moisture in the air and return to soft. The residence time of cartons in the process of production and processing should be shortened as far as possible, so as to avoid being exposed to humid air for too long and return to soft. Water vapor should be isolated from the workshop directly.
