PVC has non-flammability, high strength, weather resistance and excellent geometric stability, and has strong resistance to oxidizing agents, reducing agents and strong acids. In addition, because of its good flexibility, shrinkage and opacity, good processing and labelling performance, strong chemical corrosion resistance, and durability, it is suitable for long-term outdoor use.
PVC has excellent inking properties which can be made into various colors, and it has a wide range of applications. It is suitable for labels with high-performance requirements such as water, oil and chemical resistance, and because of its flexibility and other properties, it is commonly used in some high-end occasions such as toilet supplies, cosmetics, electrical products and jewellery.
However, PVC has poor thermal stability and light resistance, and it can start to decompose and release hydrogen chloride (HCl) gas at temperatures above 140 °C, which is not conducive to environmental protection (alkaline stabilizers and HCl are often added in actual production to inhibit its catalytic cracking reaction. ). And some toxic auxiliary materials such as plasticizers and anti-ageing agents are added in the manufacturing process to enhance their heat resistance, toughness, ductility, etc., so the products generally do not store food and medicine. In addition, due to the poor degradability of PVC label materials, it has a negative impact on environmental protection.
