When the ambient humidity increases, the process performance of the cardboard drops sharply, mainly reflected in the dehumidification and loosening of the cardboard in the heavy-duty carton packaging, the reduction of the physical index value, and the reduction of the compression resistance of the heavy-duty carton. A head tide can cause considerable damage to our outer packing cartons. Heavy-duty carton packaging is easy to collapse and deform after loading and stacking. Cracking of cartons and chaotic stacking will immediately cause damage to the products in the cartons. This situation has become a recurring persistent problem throughout the heavy carton packaging manufacturing industry.
The heavy-duty carton packaging factory tells you that when storing and using large wet cartons, relevant mutual coordination and operations should be done in the following stages:
Heavy-duty carton packaging should be stacked neatly before stacking, and should not be stacked too high, so as not to collapse the heavy-duty carton packaging. Or solve the wet weather and continue to check the cracking level of the carton strength. In addition, the cartons should be placed on the top of the pallet to keep the cartons at a certain distance from the road, so as to prevent the cartons from being re-wet due to the rising tide of the soil layer, which will reduce the quality of the cartons. Cartons should also be placed on the pallet as much as possible so that the cartons do not protrude beyond the edge of the pallet.
2. When packing and storing heavy cartons, the warehouse should be kept dry, the doors and windows of the warehouse should be closed tightly, and the cartons should be kept away from windows or gates. In order to prevent the carton from being exposed to the internal moisture of the external natural environment, the moisture content of the carton will increase, the carton will become loose, and the quality will decrease. In addition, in order to maintain the carton as quickly as possible, it will not return to moisture.
3. Lime powder is the catalyst carrier, and 1kg of quicklime powder can absorb about 0.3kg of water in the air. In the case of drizzling rainy days, quicklime powder can be packed in hemp and placed in various parts of the warehouse so that the gas inside the warehouse remains dry.
4. Cardboard stored for a period of time or heavy-duty carton packaging used in commodity circulation. If the carton is found to be soft before use, it is recommended to pull this batch of heavy-duty carton packaging to a naturally ventilated place for drying. This method increases the compressive strength of the cardboard/heavy carton to a certain extent when wet.
5. In the continuous rainy season, if there are strict regulations on the compressive strength of heavy-duty carton packaging (insufficient tensile strength will cause serious harm), and the main parameters of today's papermaking technology performance equipment cannot resist the deterioration of physical index values, it can be moderately Improve heavy-duty carton packaging materials to reduce damage to the compressive strength of cartons in cold and humid natural environments.
