Carton is a commonly used packaging product. Corrugated boxes have good applications in all industries, but cartons are also products that are more susceptible to moisture. Therefore, the Langfang carton manufacturer has brought us some moisture-proof methods for cartons. Help everyone use cartons better.
Corrugated cardboard box is a kind of corrugated cardboard made of cardboard and corrugated base paper. This kind of carton is very light and strong, and it is also convenient for everyone to load, unload and transport. For example, it is more used in some industries such as food and home appliances. The corrugated boxes produced by Langfang Carton Factory are green and environmentally-friendly cartons, which occupy a very important position in our product packaging.
However, the raw material of corrugated boxes is mainly corrugated paper, so we still need to pay more attention to the moisture-proof of this product during use. So how should the corrugated box be treated with moisture.
We can deal with it from two aspects, one is to treat the cardboard of the corrugated box to make it moisture-proof, and the other is to treat the pulp slurry to make it moisture-proof.
The carton board can be processed from many aspects. If it is to process the surface of the board, we can use coating treatment, impregnation treatment, composite treatment, etc. If you choose a moisture-proofing agent, there are also many kinds of moisture-proofing agents, such as single-component moisture-proofing agents, moisture-proofing agents made from waste plastic foam and emulsion-type moisture-proofing agents with wax as the main component. Surface sizing agent can also be used. Surface sizing technology can improve the surface strength of the carton and the hydrophobicity of the cardboard.
If we use the method of processing pulp slurry, we can often add some sizing agent to the pulp in the production process of box board and corrugated base paper, so that the board has the ability to prevent the diffusion or penetration of aqueous liquids. It can also adopt biological pulping treatment methods and adopt appropriate moisture-proof technology to produce moisture-proof corrugated cardboard, which can achieve the required moisture-proof performance at a lower cost.
