In our packaging industry, pearl cotton is a very common material. Manufacturers of pearl cotton sheets discuss why pearl cotton is used for packaging. It is widely used in construction boards, but to choose durable boards, some purchasing knowledge must be understood. Only in this way can good board materials be purchased. Here are the aspects to pay attention to when selecting pearl cotton sheets. 1. **Brand is Important** With many pearl cotton sheets available in the market, the quality can vary. To ensure that the sheets provide good sound insulation, thermal insulation, and shock resistance, and can be used for a long time, it is recommended to choose branded products when making a purchase. 2. **Product Filling** Some products, such as children's toys, bags, etc., will have filling materials during the production process. Pearl cotton sheets are excellent filling materials because these products are odorless and have no side effects, making them suitable for small toys and bags without causing pollution or damage to the natural environment. 3. **Water-Resistant Products** The raw materials used for pearl cotton sheets do not absorb water, which is why they are widely used in water-resistant applications. Among them, furniture and wooden floors are more common. When installing wooden floors in a home, a layer of pearl cotton sheets is generally laid on top of the concrete base as a moisture-proof mat, and then the wooden floor is laid on top. This effectively protects both the wooden floor and the concrete base.
