‌ PVC packaging sheet is a hard plastic sheet mainly made of polyvinyl chloride (PVC), and is widely used in vacuum packaging for food, electronics, medicine, daily necessities, etc.
PVC sheet materials possess the following core characteristics:
High transparency and luster: It can clearly display the contents of the product, enhancing the display effect of the goods, and is often used for high-end gifts and cosmetic packaging.
Excellent thermoforming performance: It is easy to be processed into various complex shapes of trays, shells and liners through vacuum thermoforming, with low mold costs and high production efficiency.
Good impact resistance and stiffness: It can effectively protect the product during transportation and reduce damage.
High degree of customization: It supports functional modifications such as color, thickness, size, and anti-static, flocking, etc., to meet diverse packaging needs. Strong heat sealing ability: It is convenient for compounding with paperboard and other materials, and is used for making card-holding packaging.
According to different uses, PVC packaging sheets are mainly divided into:
Transparent PVC sheet: Used for packaging that needs to display contents, such as toys, electronic products, stationery, etc.
Colorful/ frosted/ flocking PVC sheet: Enhances the texture of the packaging, often used in gift boxes and cosmetic holders.
Anti-static PVC sheet: Suitable for packaging of precision electronic components to prevent static damage.
Environmentally friendly PVC sheet: Uses non-toxic stabilizers and environmentally friendly plasticizers, complies with food contact standards, and can be used for primary packaging of candies, pastries, etc.
It should be noted that PVC releases hydrogen chloride gas when burned, and its environmental friendliness is relatively poor. Moreover, some products containing plasticizers may have migration risks. Therefore, in scenarios with food and environmental protection requirements, PVC is gradually being replaced by PET and other materials.
