How is the moisture-proof and waterproof performance of blister box?
Publish Time: 2025-02-17
In the packaging industry, moisture-proof and waterproof performance are one of the important indicators to measure the quality of packaging materials. PVC (polyvinyl chloride) and PET (polyethylene terephthalate) are two common blister box materials, which are favored for their good moisture-proof and waterproof performance. This article will focus on the performance of PVC/PETblister box in this regard.
Due to the characteristics of the material itself, PVCblister box has certain moisture-proof and anti-static capabilities. The chlorine atoms in the molecular structure of polyvinyl chloride make it have a certain chemical stability and can effectively prevent the penetration of water molecules. Therefore, PVCblister box can maintain a good dry state in a humid environment and protect the internal products from moisture. At the same time, PVC material also has good anti-static properties, which can avoid dust adsorption and water condensation caused by static electricity, further enhancing its moisture-proof effect.
PETblister box also has excellent moisture-proof and waterproof performance. PET material has a tight molecular structure, low surface tension, and is not easy to absorb water, so it has excellent waterproof performance. During the manufacturing process, PETblister box usually adopts hot blister process to make the box body form an integrated structure, reduce the presence of seams and gaps, and thus improve the waterproof performance. In addition, PET material also has high strength and toughness, can resist external impact and extrusion, and protect the internal products from damage.
In practical applications, the moisture-proof and waterproof performance of PVC/PETblister box has been widely verified. For example, in the field of food packaging, PVC/PETblister box is often used to package biscuits, candies and other moisture-sensitive foods, which can effectively keep the food dry and fresh. In the packaging of electronic products, PVC/PETblister box can also effectively prevent moisture from eroding electronic components and ensure the safe transportation and storage of products.
It should be noted that although PVC/PETblister box has good moisture-proof and waterproof performance, its performance may be affected to a certain extent under long-term immersion or extremely humid environment. Therefore, when selecting and using it, it is necessary to make comprehensive considerations based on specific application scenarios and needs.
In summary, PVC/PETblister box plays an important role in the packaging industry with its excellent moisture-proof and waterproof performance. Whether it is food packaging, electronic product packaging or other fields, PVC/PETblister box can provide effective protection for products.
