The density of PVC cosmetic bag materials is the core of waterproof performance


As a synthetic polymer material, polyvinyl chloride is widely used in the production of various industrial and consumer products with its good physical and chemical properties. The molecular structure of PVC materials is compact and non-porous, which can effectively block the penetration of water and other liquids. This high density gives PVC materials excellent waterproof performance, which is the fundamental reason for its wide application in the field of cosmetic bags.
Molecular structure and waterproofness of PVC materials
The molecules of PVC materials are formed by polymerization of vinyl chloride monomers, and their molecular structure shows the characteristics of linear polymerization. In the process of linear polymerization, the molecular chains are tightly bound by van der Waals forces and dipole interactions to form a highly dense material. This dense structure makes it difficult for water molecules to penetrate through the gaps between molecules, thereby achieving a waterproof effect.
In the industry, the water absorption rate of PVC is usually less than 0.1%, which means that it absorbs almost no water when it comes into contact with water. This feature is particularly suitable for the production of cosmetic bags, because cosmetic bags often need to contact liquid cosmetics or be exposed to humid environments, and low water absorption ensures that the items in the bag are always dry.
Sealing design of PVC cosmetic bags
In addition to the density of the material itself, Ningbo Jiusheng Bags Co., Ltd. has also invested a lot of energy in the design of PVC cosmetic bags to ensure the overall waterproof performance of the product. The company has adopted a waterproof sealing design on the zippers, seams and edge treatment of the cosmetic bags.
For example, waterproof zippers are an important component in PVC cosmetic bags, which can effectively block the entry of moisture when zipped. The company uses high-quality waterproof zippers and uses professional assembly processes to ensure that each zipper can be used smoothly and provide reliable waterproof protection when closed.
On the seams, the company uses high-density sewing technology to ensure that the gaps between the seams are as small as possible, thereby reducing the risk of moisture penetration. In addition, the seams are usually sealed twice, such as using waterproof tape or heat sealing process, to further enhance the waterproof effect.
