How to make display cardboard shelves moisture-proof

In the retail industry, display cardboard shelves are widely used because of their lightness and economy, and have become the preferred choice of many merchants. However, the physical properties of cardboard make it extremely sensitive to humidity. A humid environment may cause the shelves to deform, lose strength, or even collapse, which not only affects the display effect of the product, but also seriously damages the customer's shopping experience. Therefore, it is particularly important to effectively treat the display cardboard shelves with moisture.

Choose the right cardboard material
High-strength moisture-proof cardboard
In the design and manufacturing process of display cardboard shelves, the selection of high-strength moisture-proof cardboard is a crucial step. There are some cardboard materials on the market that are designed for environments with high humidity, such as waterproof corrugated cardboard and coated cardboard. These materials are specially treated to effectively resist the intrusion of moisture, thereby reducing the risk of deformation and damage.
Honeycomb cardboard
Honeycomb cardboard has good strength and lightweight characteristics due to its unique structural design. Its internal honeycomb structure not only provides excellent support, but also can effectively prevent moisture penetration by using honeycomb cardboard with moisture-proof coating, further enhancing the durability of the shelf.

Application of moisture-proof coating
Waterproof coating
Applying a waterproof coating on the surface of cardboard shelves is an effective moisture-proof treatment method. Waterproof coating can form a protective film to effectively prevent moisture penetration. Commonly used waterproof coatings include polyethylene (PE) coating and polyurethane (PU) coating, which not only provide excellent waterproof performance, but also enhance the wear resistance of cardboard.
Moisture-proof spray
Using moisture-proof spray is also a simple and effective moisture-proof measure. These sprays usually contain waterproof ingredients that can form a protective film on the surface of the cardboard. After spraying, make sure the surface of the shelf is dry to form an effective moisture-proof barrier.

Physical moisture-proof measures
Bottom moisture-proof treatment
Adding moisture-proof pads or using moisture-proof materials (such as plastic film or rubber pads) at the bottom of the shelf can effectively block the rise of ground moisture. In a humid environment, moisture-proof treatment at the bottom is crucial, which can not only extend the service life of the shelf, but also ensure the stability and safety of the shelf.
Ventilation design
When designing display cardboard shelves, ventilation design should not be ignored. By increasing the gap between shelves or adopting an open structure, air circulation can be effectively promoted and humidity accumulation can be reduced. In addition, avoiding close contact between shelves and walls or other objects can help improve ventilation and reduce the impact of humidity on shelves.

Environmental control
Suitable storage environment
When using display cardboard shelves, try to place them in an environment with low humidity. Using a dehumidifier or air conditioning equipment can effectively control the indoor humidity, and it is recommended to keep it between 40%-60%. Regularly monitor the ambient humidity and take timely measures to adjust it to ensure the long-term stability of the shelf.
Avoid direct sunlight
Cardboard shelves should avoid direct exposure to sunlight, because direct sunlight will cause the surface temperature of the cardboard to rise, resulting in uneven evaporation of moisture and increasing the risk of deformation. Appropriate shielding measures or the use of curtains can effectively protect the cardboard shelves and ensure that they are used in the best condition.
