What kind of packaging material is more safe for the desiccant? We learned that different desiccants use different packaging materials. The desiccant packaging materials must have good air permeability, strength and excellent heat sealability.
1. The filter paper has good air permeability, and the disadvantage is that it is easy to leak ash. It can be used for small size silica gel desiccant packaging, but it cannot be used for montmorillonite desiccant packaging, because montmorillonite desiccant is not strong enough and leaks powder easily;
2. Non-woven fabric has both a certain strength and excellent air permeability and adhesion. The disadvantage is easy ash leakage, which can be used for silica gel desiccant packaging, but used for packaging montmorillonite and easy to leak powder;
3. Composite paper is cheap, but has poor air permeability, which results in slow moisture absorption, and is generally not suitable for moisture-proof packaging of electronic products;
4. Textured paper has good air permeability, high strength, good dust resistance, wide applicability, higher price than ordinary composite paper, but far lower than DuPont paper, and is an ideal choice for high-end packaging materials;
5. There are two types of wax paper: transparent wax paper and milky wax paper. They have good oil and water resistance, good heat-sealability, and can identify the inner package through the paper.
6. Aihua paper is woven with special fibers. Through the paper, the packaged objects can be clearly identified. It is called transparent Aihua paper. This material has good air permeability, good fabric density, smooth and flat surface, and good heat sealing performance. , Mainly used for packaging of food desiccant and pharmaceutical desiccant.
7. Tyvek is commonly known as "tear-proof", also known as DuPont paper. It is an ideal material for various desiccant packaging. It has high strength, folding resistance, tear resistance, antistatic, and good air permeability. Features, also has excellent weather resistance and chemical resistance, dust-free design, used in packaging desiccant, both good air permeability, but also sufficient strength and beautiful printing effect, the disadvantage is that the price is high.
