What are the desiccant wrapping paper? how to choose?
The desiccant packaging material should have good air permeability, strength and heat sealability. Different packaging materials can be selected according to the application industry and weight. The currently widely used desiccant packaging materials mainly include: non-woven fabrics, breathable filter paper, Aihua paper, Dulai paper, composite paper, opp film, net Textured paper, fiber non-woven fabric, deoxidizer wrapping paper, DuPont paper, etc.
1. The filter paper has good air permeability. The disadvantage is that it is easy to leak dust. It can be used for small-size silica gel desiccant packaging, but it cannot be used for smectite desiccant packaging, because the montmorillonite desiccant is not strong enough and easily leaks powder.
2. Non-woven fabric: Non-woven fabric is made of oriented or random plastic fibers, and it is a widely used common packaging material. It has certain strength, excellent air permeability and adhesion. The disadvantage is that it is easy to leak dust. It can be used for silica gel desiccant packaging, but it is easy to leak powder when used for packaging montmorillonite.
3. The price of composite paper is cheap, but the air permeability is poor, resulting in slow moisture absorption, and is generally not suitable for moisture-proof packaging of electronic products
4. Opp coated plastic packaging, a desiccant packaging material for food. Its characteristics are oil-proof and waterproof, and it is applied to fried foods, puffed foods, etc., which is moisture-proof, mildew-proof and safe. According to the different requirements of the customer's use environment, we can produce different specifications of film packaging. It is not only used for desiccant packaging, but also widely used in other fields.
5. Aihua paper has good air permeability, good fabric density, smooth and flat surface, and good heat sealing performance. It has good permeability and is pressed on a book, which can clearly identify the text under the paper. The density is good, the granular products are packed, and the dust leakage is small. Excellent air permeability, close to the air permeability of non-woven fabrics on the market. Good heat sealing performance, three-side seal, four-side seal and back seal can be used. Mainly used for the packaging of food desiccant and medicine desiccant.
6. Dulai paper: Dulai paper is not easy to tear by ordinary artificial force. Good water resistance: After being wet and soaked, it still has the same strength and will not become rotten. Air permeability: It has better air permeability than a sheet of paper. Excellent chemical resistance: not afraid of most strong acids, strong bases, and salts. Tensile Tension: The stretch and shrink ratio of the paper surface is less than 0.01% when it is wet to dry. Antistatic: After a special antistatic treatment, it does not generate static electricity and has a dustproof effect. Environmentally friendly products: Burning only Dulai paper, leaving only water vapor and carbon dioxide, does not affect the environment.
7. Anilox paper has good air permeability, high strength, good dust resistance, wide applicability, and the price is higher than ordinary composite paper, but far lower than DuPont paper. It is an ideal choice for packaging materials;
8. Tyvek, commonly known as "tear not rotten", also known as DuPont paper, is an ideal material that can be used for various desiccant packaging, with high strength, folding resistance, tear resistance, anti-static, good air permeability, etc. Features, also has excellent weather resistance and chemical resistance, dust-free design, used for packaging desiccant, not only has good air permeability, but also has sufficient strength and beautiful printing effect, the disadvantage is high price.
