The types of desiccants can be roughly divided into several types:
1. Silica gel desiccant
The raw material is a kind of hydrated silica with high microporous structure, which is colorless, odorless, non-toxic, stable in chemical properties, and good in moisture absorption. Widely used in instruments, instruments, leather, luggage, food, textiles, equipment, etc. Its function is to control the relative humidity of the environment during storage and transportation of food sealer bags, and to prevent items from getting damp, mildew and rust.
2. Fiber desiccant
Its biggest feature is that it is made of pure natural plant fiber and refined through a special process. It is worth mentioning that the coated fiber desiccant sheet saves space in food sealer bags, which is convenient and practical. Its moisture absorption capacity is equivalent to its own weight, much higher than other desiccants. Due to its moderate price, safety and sanitation, it is the best choice for many health care products, medicines and biological desiccants.
3. Montmorillonite desiccant
Food sealer bags are widely used in medical and health care, food packaging, optical instruments, electronic products, military products and civilian products. These products cannot be sealed with oil seals and weather. Due to the use of pure natural raw material bentonite, it has the characteristics of strong adsorption capacity, fast adsorption speed, odorless, non-toxic, non-environmental pollution, and non-contact corrosion. It is environmentally friendly, odorless, non-toxic, does not harm the human body, has good adsorption performance, has adsorption activity, static moisturizing, deodorizing and other effects.
