How to choose thermal paper depends on the needs of your industry. If it needs to be preserved for a long time or used in catering, you can choose three-proof heat-sensitive paper, which can be waterproof, oil-proof and alcohol-proof. If it is usually used for numbering, you can choose ordinary thermal paper; When choosing thermal paper, it depends on whether the coating of thermal paper will be uneven. The uneven color of some thermal paper indicates that the quality is not very good. If a large amount of thermal paper is needed, the choice depends on the manufacturer. Manufacturers must have large scale and advanced equipment to ensure timely delivery. There is a manufacturer of thermal paper, headquartered in Shenzhen. The factories of Sinbad Group are quite large. They have advanced equipment, good quality and quantity.
