The raw materials of long-acting three heat-proof paper show their special features in many aspects, which together constitute the excellent waterproof, oil-proof, anti-friction properties of the paper. The following is a detailed analysis of the special features of its raw materials:
1. paper-based materials
High quality pulp: Long-life thermosensitive paper usually uses high quality pulp as the base material, which may include a mixture ratio of coniferous wood pulp and hardwood pulp to ensure the strength, smoothness and printing effect of the paper.
Special additives: In order to improve the durability and three-proof performance of the paper, special additives may be added to the pulp, such as water-proof agents, oil-proof agents, etc.
2. heat sensitive coating
Special thermal dyes: The thermal coating of the long-acting triple thermal paper uses special thermal dyes, which can quickly change color when heated and display clear images or text.
Stabilizers: In order to maintain the stability and durability of the heat-sensitive coating, stabilizers may be added to prevent the dye from fading or deterioration in harsh environments such as high temperature and humidity.
3. three prevention treatment layer
Waterproof agent: The waterproof performance of long-acting three heat-proof paper is mainly due to the waterproof treatment layer on its surface. This special waterproof agent can effectively prevent water from penetrating the inside of the paper, keeping the paper dry and clear.
Oil repellent agent: Oil repellent agent is used to treat the surface of the paper, so that it has excellent oil resistance. These oil repellents resist the attack of various oils, ensuring that the label remains legible after contact with the oil.
Wear-resistant material: In order to improve the wear resistance of the paper, the surface of the long-acting three heat-resistant paper may also be coated with a layer of wear-resistant material. This layer of material can effectively resist scratching and wear, extending the service life of the label.
4. Other special materials
Environmentally friendly glue: In some applications of long-acting heat-resistant paper (such as self-adhesive labels), environmentally friendly strong glue may be used as a bonding material. These glues are not only sticky and not easy to fall off, but also meet environmental requirements.
Multi-layer structure: In order to further improve the performance and stability of the paper, the long-acting three-layer thermal sensitive paper may use a multi-layer structure design. These layer structures may include coating, surface material, retention agent, adhesive, silicon coating layer, backing paper and coating base, each layer has its specific function and role.
In summary, the raw materials of long-acting three-proof thermal paper show their special characteristics in terms of paper-based materials, thermal coatings, three-proof treatment layers and other special materials. Together, these special materials and technologies give long-lasting thermal paper excellent performance, making it legible and stable in a variety of harsh environments.
