"Silica gel" is a spherical desiccant with extensive adsorption properties due to chemical and physical adsorption. Its structure consists of closely packed fine particles of silicon dioxide that form a continuous network of tiny pores. Additionally, silica gel is made of highly pure (over 99%) silicon dioxide, which is chemically safe and non-toxic. It is not digested or absorbed in the body, so there is no concern about poisoning even if accidentally ingested. 【Features】 ■ Extensive adsorption properties ■ Chemically safe and non-toxic ■ No risk of poisoning if accidentally ingested, as it is not digested or absorbed in the body ■ JIS standard product (JIS-Z-0701) *For more details, please refer to the PDF document or feel free to contact us.

"Container Dry" is a desiccant that solves problems such as mold, corrosion, white mold, decay, and warping caused by moisture during container, railway, and truck transportation. It has a moisture absorption rate of approximately 280%, and after absorbing moisture, it turns into a gel state and does not release moisture back into the environment. Additionally, it is non-toxic, making it safe to use. We offer several types according to your needs and transportation methods. ========================== ~Inside the container during transportation...~ 1. Air and moisture enter along with the products when they are packed. 2. Condensation may occur due to weather conditions during maritime shipping... By using "Container Dry," you can maintain the dew point temperature lower than the surface temperature during transportation, preventing condensation damage! ========================== 【Features】 ■ Does not release moisture back outside ■ Prevents damage from condensation ■ Safe and non-toxic ■ Effect lasts for about 90 days depending on conditions and usage *For more details, please download the PDF or feel free to contact us.
