How corrugated boxes avoid moisture

Corrugated box packaging is a widely used packaging product, the amount has been large, is the main force of transport packaging. In addition to protecting goods, facilitating storage and transportation, it also plays a role in beautifying goods and promoting goods. However, the main components of Shijiazhuang corrugated carton packaging are cellulose, hemicellulose, lignin, etc., which means that it has strong hydrophilicity and high moisture absorption ability.
The moisture content of the corrugated box is too high, which will cause the phenomenon of corrugated shape change and binder hydrolysis, directly reducing its compressive strength, bursting strength and aesthetics, while the corrugated box has strong moisture absorption, and when the ambient humidity is too high, the corrugated box will directly absorb moisture from the air, and its own moisture content will continue to increase. When controlling the ambient humidity, and avoid the use of desiccant, because the corrugated box itself has high moisture absorption, it is an alternative "desiccant" in itself, and even the desiccant used is not necessarily higher than the corrugated box.
Therefore, the corrugated box packaging is packed with enhanced ventilation when stored. Ventilation is conducive to moisture dispersion and moisture, and large-scale storage should ensure mechanical ventilation. However, attention should be paid to humid, humid weather and avoid ventilation. It is recommended that the air conditioning system can also be used, normal temperature changes have little effect on the performance of the corrugated box, but the air conditioner must be accompanied by this humidity drop when the temperature control is carried out, and some have a separate dehumidification mode or constant temperature and humidity control, so after evaluation, if necessary, the corresponding air conditioning system can be used. In addition, the dehumidifier can directly control the ambient humidity continuously for a long time, which is essential in the storage of moisture-proof, humid weather, re-humid weather and daily moisture-proof can work effectively, the cost is lower than the air conditioner, and can also be combined with the fresh air system, the fresh air dehumidification system can combine ventilation and dehumidification.
