Why Put Desiccant in The Food Bag?

Food desiccants are generally non-toxic, tasteless, non-contact corrosive, no environmental pollution. Food desiccant is to reduce the humidity in food bags and prevent food spoilage corruption.

For food desiccants, they can be divided into the following categories:

1. Fold the raw lime desiccant

The main component of lime desiccant is calcium oxide, its water absorption capacity is achieved by chemical reaction, so water absorption is irreversible. Regardless of the humidity of the external environment, it can maintain more than 35% of the self-weight of the hygroscopic capacity, more suitable for low temperature preservation, with excellent dry moisture absorption effect, and low price. Can be widely used in food, clothing, tea, leather, shoes, electrical appliances and other industries. This type of desiccant is used in the most common "snow cakes". However, raw lime desiccants due to strong alkali corrosion, often hurt children or the eyes of the elderly, has been gradually eliminated.

2. Fold the silicone desiccant

This desiccant is a different variety of silicone in permeable pouch packaging, the main raw material silicone is a high microporous structure of water-containing silica, non-toxic, tasteless, odorless, chemically stable, with strong moisture absorption properties. Therefore, it is widely used in instruments, instruments, equipment, leather, bags, footwear, textiles, food, medicine and other storage and transportation to control the relative humidity of the environment, to prevent moisture, mold and rust. Xylitol, for example, is used and is the only desiccant approved by the European Union.

3. Fold the montstone desiccant

This desiccant uses pure natural raw materials bentonite, green environmental protection, non-toxic tasteless, no damage to the human body. It has good adsorption performance at room temperature and general humidity, has adsorption activity, has static dehumidification and odor removal and other effects. Not only fast adsorption speed, high adsorption capacity, and non-toxic, tasteless, non-contact corrosive, no environmental pollution, especially used in food packaging, harmless to human body. Scope of application: widely used in products that cannot be sealed with oil, gas phase, such as: optical instruments, electronic products, medical health care, food packaging and military and civilian products dry air storage.

4. Fold the calcium chloride desiccant

Calcium chloride desiccant is the main raw material is calcium chloride, is the use of high-quality calcium carbonate and hydrochloric acid as raw materials, by the reaction synthesis, filtration, evaporation concentration, drying and other processes refined. White porous block, granular, or honeycomb solid. The taste is bitter and odorless. The aqueous solution is colorless. Mainly used as inorganic chemical production of other kinds of calcium salt raw materials; It is also used as a desiccant for gases and as a dehydrator when producing alcohols, esters, ethers and acrylic resins. Used as calcium fortifiers, curing agents, chelating agents, desiccants, etc. in the food industry.

5. Fold fiber desiccant

Fiber desiccants are made from pure natural plant fibers that are refined by special processes. In particular, film fiber desiccant tablets, convenient and practical, do not occupy space. Its moisture absorption capacity of 100% of its own weight, is ordinary desiccant can not be compared. In addition, the product is safe and hygienic, affordable, is ideal for many biological, health food and pharmaceuticals.
