Established in 1998 , Chunwang company is a set of R&D, production and marketing enterprise, specialized in desiccants, oxygen absorbers, bamboo charcoal bag. Desiccant refers to a substance that can remove moisture from moist materials. It is often divided into two categories: chemical desiccants, such as calcium sulfate and desiccant calcium chloride, which are dried by combining with water to form hydrates. Electronic products can also cause oxidation of metals due to excessive humidity, which can cause defects. Therefore, storage box dehumidifier can protect them. The use of super dry desiccant is to avoid the occurrence of defective products caused by excess moisture. The best air purifying bag has a hard texture, good ventilation, good adsorption. Natural air purifying bag can absorb formaldehyde, benzene, TVOC, sulfur dioxide and other harmful substances. We also have humidity control packet and bamboo charcoal fresh air purifying bag. The bamboo charcoal air purifying bag has the characteristics of fine and porous, hard texture, good air permeability, good water permeability, good water retention and large surface area as well as bamboo charcoal bag odor absorber, best air purifying charcoal bags. As an excellent physical and chemical adsorbent, activated bamboo charcoal bag has attracted more and more attention. It is recommended that air purifying bamboo charcoal odor bag is used for deodorization, removal of formaldehyde, humidity control, deodorization, mildew, air purification and food preservation. We also have nature bamboo charcoal air purifying bag and bamboo charcoal deodorizer bag. Food preservatives such as oxygen removal packets and oxygen absorber packets are used to prevent deterioration of foods caused by microbial growth during storage and distribution, or due to poor storage and sales conditions, inferior quality of foods, and decreased color, in order to improve the shelf life and extend the value of food. The oxygen scavenger can lower the pH value, inhibiting the growth of microorganisms, and weakening the heat resistance of microorganisms, thereby promoting the effect of heat sterilization.
