The production process of small roll thermal label paper has undergone a number of improvements in recent years, which are aimed at improving production efficiency, product quality and environmental performance. The following are some of the main production process improvements:
1. Raw material selection and formula optimization
Raw material selection: With the improvement of environmental awareness, the raw material selection of thermal label paper is more inclined to environmentally friendly materials. For example, choose degradable paper-based materials, non-toxic and harmless thermal coatings, etc., to reduce the impact on the environment.
Formulation optimization: The formulation of thermal coatings is continuously optimized to improve its color sensitivity, stability, water resistance and chemical resistance. The preservation performance and durability of heat-sensitive label paper can be significantly improved by adding water-resistant agent, cross-linking agent or microencapsulation technology.
2. Coating process improvement
Coating equipment upgrade: The use of more advanced coating equipment and technology, such as precision coating machine, micro-gravure coating, etc., to improve the uniformity and accuracy of the coating. These devices can better control the thickness and distribution of the paint, thereby improving the printing effect of thermal label paper.
Multi-layer coating technology: The use of multi-layer coating technology, such as base coating, top coating and protective coating, to improve the overall performance of thermal label paper. For example, the base coating can enhance the bond between the paper and the paint, the top coating can improve the color rendering effect, and the protective layer can extend the storage life of the thermal label paper.
3. Drying and curing technology
Efficient drying equipment: The use of efficient drying equipment, such as hot air dryer, infrared dryer, etc., to speed up the drying speed of the coating and improve production efficiency. At the same time, these devices can better control the temperature and humidity during the drying process to ensure the quality of the coating.
Curing technology: Advanced technologies such as ultraviolet curing and electron beam curing enable the coating to cure rapidly in a short time, thereby improving the hardness and wear resistance of the heat-sensitive label paper. These curing technologies can also reduce the volatilization of solvents and reduce environmental pollution.
4. Cutting and slitting technology
Automatic cutting machinery: The use of automatic cutting machinery for precise cutting of thermal label paper to improve production efficiency and yield. These machines are capable of fast and accurate cutting according to preset sizes and specifications to meet the needs of different customers.
Slitting technology: The thermal label paper is slitted to form a single sheet or roll label paper. By optimizing the slitting process and equipment, the waste and loss in the slitting process can be reduced and the utilization rate of materials can be improved.
5. Quality control and testing
Strict quality testing: In the production process, strict quality testing of raw materials, semi-finished products and finished products. By testing the flatness of the paper, the uniformity of the coating, the printing effect and the durability, we ensure that the quality of the thermal label paper meets the standards and customer requirements.
Intelligent monitoring system: The introduction of intelligent monitoring system for real-time monitoring and data acquisition of the production process. Through data analysis and mining, timely find and solve problems in the production process, improve production efficiency and product quality.
6. Environmental protection and sustainability
Application of environmentally friendly materials: actively promote and apply environmentally friendly materials to reduce the emission of harmful substances and the impact on the environment. For example, choose degradable paper-based materials, non-toxic and harmless thermal coatings, etc.
Energy saving and emission reduction measures: Take energy saving and emission reduction measures in the production process, such as optimizing the production process, improving the efficiency of equipment, recycling waste, etc., to reduce energy consumption and reduce carbon emissions.
In summary, the production process of small roll thermal label paper has made significant improvements in raw material selection, coating process, drying and curing technology, cutting and slitting technology, quality control and testing, as well as environmental protection and sustainability. These improvements not only improve production efficiency and product quality, but also promote the sustainable development of the thermal label industry.
