During storage, industrial-grade kraft paper bags are susceptible to environmental factors such as moisture and compression, which may lead to damage to their structure and affect the quality and safety of the packaging. To ensure that these paper bags are in optimal condition during storage, a series of measures are needed to avoid interference from factors such as moisture and compression.
The temperature and humidity of the storage environment are crucial to the effect of kraft paper bags. Excessive humidity will cause the fibers of the paper bag to absorb water, which will soften, expand, and even break or tear. Therefore, it is very important to ensure dryness in the storage area. The ideal storage environment should avoid humid air, keep the relative humidity within an appropriate range, and avoid moisture absorption of paper bags. In addition, the humidity in the storage environment can be further reduced by using a desiccant or a hygroscopic material, thereby maintaining the integrity of the paper bag.
The choice of storage location is also very critical. Kraft paper bags should avoid direct contact with the ground, especially in areas with wet ground. During storage, paper bags should be stacked on a tray or shelf to ensure air circulation and avoid direct contact with moisture from the ground. In addition, avoid exposing the paper bag to the sun during storage to avoid heat and UV rays affecting the quality of the paper bag.
In order to avoid the impact of compression on paper bags, paper bags should be avoided to be stacked too densely during storage. Excessive compression may cause changes in the morphology of the paper bag, increasing the risk of its damage. When stacking, proper spacing should be maintained to avoid heavy pressure and ensure that the shape and structure of the paper bag are not subject to excessive squeeze. If the paper bag is stored in roll shape or folded, make sure the folding and curling angles do not put extra stress on the paper bag.
It is also very important to regularly check the status of the kraft paper bag during storage. Regular inspections can promptly detect whether the paper bag is damp, deformed or affected by other external factors. If the paper bag is found to be damp or damaged, measures should be taken immediately, such as removing the damaged paper bag out of the storage area and replacing or repackaging.
In addition to environmental control and regular inspections, kraft paper bags treated with waterproof or moisture-resistant coatings can further enhance their moisture resistance. This type of treatment can effectively prevent moisture from invading the inside of the paper bag, thereby protecting the materials in it from moisture. If the paper bag has good waterproof and moisture resistance, it can maintain its quality better even if stored in a humid environment.
