How to ensure the quality stability of long-lasting three proof thermal paper?

To ensure the quality stability of long-lasting three proof thermal paper, the following aspects can be taken into account:

1、 Choose high-quality raw materials

The quality of long-lasting three proof thermal paper depends first and foremost on its raw materials. High quality raw materials should have the following characteristics:

Paper base: The paper base should have good strength and stability, be able to withstand various mechanical stresses during the printing process, while maintaining flatness and uniformity.

Thermal sensitive coating: The thermal sensitive coating should be uniform and delicate, ensuring consistent color depth during printing, and have good thermal responsiveness.

Protective layer: The protective layer should have waterproof, oil resistant, scratch resistant and other characteristics, while not affecting the normal reaction of the thermal sensitive coating.

2、 Production process control

The production process has a significant impact on the quality stability of long-lasting three proof thermal paper. Here are some key production process control points:

Coating process: The coating process should ensure that the thermosensitive coating and protective layer are evenly and finely coated on the paper substrate, avoiding uneven coating that can lead to a decrease in printing quality.

Drying process: The drying process should be appropriate to ensure uniform drying of the coating and avoid insufficient or excessive drying that may cause paper deformation or coating peeling.

Curling and cutting: Curling and cutting processes should be precise to ensure that paper size and shape meet specification requirements, reducing the occurrence of paper jams and printing failures.

3、 Storage condition management

Long term three proof thermal paper also needs to pay attention to the following points during storage to ensure its quality stability:

Temperature and humidity: It should be stored in a cool and dry environment, avoiding direct sunlight and high temperatures, while maintaining appropriate humidity to prevent paper from getting damp or excessively dried.

Packaging and sealing: Use moisture-proof paper or film for sealed packaging to prevent air and moisture from affecting the paper. For rolled paper, it should be stacked vertically; Flat paper should be stored flat to avoid being stacked too high and causing deformation under pressure.

Avoid contact with chemicals: Prevent paper from coming into contact with chemicals to prevent corrosion or deterioration of the paper.

4、 Quality inspection and monitoring

To ensure the quality stability of long-lasting three proof thermal paper, regular quality testing and monitoring are also necessary:

Appearance inspection: Check whether the appearance of the paper is flat, uniform, and free of defects such as cracks and spots.

Print test: Conduct a print test to check if the print effect is clear, if the color is uniform, and if there are any issues such as paper jams or printing faults.

Chemical performance testing: Testing the waterproof, oil resistant, scratch resistant and other properties of paper to ensure that it meets the specifications.

5、 Choose a reputable supplier

Choosing a reputable supplier is also the key to ensuring the quality stability of long-lasting three proof thermal paper. Suppliers should have stable raw material supply channels, advanced production processes, and strict quality control systems. At the same time, suppliers should also provide comprehensive technical support and after-sales service to ensure that any problems encountered by customers during use can be resolved in a timely manner.

In summary, by selecting high-quality raw materials, controlling production processes, managing storage conditions, conducting quality testing and monitoring, and selecting reputable suppliers, the quality stability of long-lasting three proof thermal paper can be ensured.
