Some desiccants in electronic products are sealed and packaged in bags. How can they work? Are there some holes in the desiccant bags?

first of all, most of the desiccants are powder, granular and crystalline. Sealed packaging makes them easy to use and transport. You mean sealed packaging. One is plastic paper. Look, there are many small holes in the packaging bag. Another is the paper packaging bag, which is breathable and the water vapor can enter naturally, so as to achieve the drying effect

desiccants refer to substances that can remove moisture from wet substances. They are often divided into two categories: chemical desiccants, such as calcium sulfate and calcium chloride, which are dried by combining with water to form hydrate; Physical desiccants, such as silica gel and activated alumina, are dried by physically adsorbing water

the control of moisture is closely related to the yield of products. In the case of food, under appropriate temperature and humidity, bacteria and molds in food will multiply at an alarming rate, causing food spoilage, moisture and color change. Electronic products will also cause metal oxidation due to high humidity, resulting in defective products. The use of desiccant is to avoid the occurrence of defective products caused by excess water

sealing, also known as sealing and sealing, refers to various sealing processes carried out after the products are packed in the packaging container in order to ensure that the contents are retained in the container or packaging bag during transportation, storage and sales, and avoid pollution and damage

there are many kinds of packaging sealing methods and materials and components used, such as adhesive cover, heat seal, binding, etc. Sealed packaging is a complex technology. Designers should consider many factors when designing sealed packaging

first of all, most of the desiccants are powder, granular and crystalline. Sealed packaging makes them easy to use and transport. You mean sealed packaging. One is plastic paper. Look, there are many small holes in the packaging bag. Another is the paper packaging bag, which is breathable and the water vapor can enter naturally, so as to achieve the drying effect!

some of the packaging materials used as desiccant have good air permeability, such as non-woven fabric and cotton paper

other packaging materials pay attention to the degree of firmness, but their air permeability is poor or not. In order to solve this problem, we need to punch holes in the packaging materials

you can observe carefully. Even if you punch holes, those holes can be seen.

desiccant bags have small holes.
