What are the main raw materials of long-acting heat-sensitive label paper?

The main raw materials of long-acting heat-sensitive label paper mainly include polyester film and polypropylene film. These two materials are widely used in the production of long-acting thermal label paper because of their unique properties.

1. Polyester Film (PET)

Characteristics: Polyester film is a polymer material with excellent heat resistance, cold resistance, chemical resistance and excellent mechanical properties. It can withstand high temperature, high humidity and high pressure and other harsh environments, uniform thickness, wear resistance, good texture, very suitable for making high-end labels.

Application: Because of its excellent performance, polyester film is often used to make long-lasting heat-resistant label paper that needs to be stored for a long time or used in harsh environments.

2. Polypropylene Film (PP)

Characteristics: Polypropylene film is a transparent, good toughness material, with good electrical insulation, chemical resistance and high temperature resistance. Its production process is mature and the cost is relatively low, so it is widely used in various labels and tapes.

Application: Polypropylene film is also often used in the production of long-acting thermal label paper, especially in cases where there are certain requirements for cost.

Sum up

The main raw materials of long-acting heat-sensitive label paper are polyester film and polypropylene film. These two materials have their own characteristics, polyester film is more excellent in performance, suitable for high-end applications; Polypropylene film is widely used in various label production because of its low cost. When selecting raw materials, the manufacturer will make a reasonable choice according to the specific use environment and customer needs of the label paper.It should be noted that the performance of long-acting heat-sensitive label paper not only depends on the raw materials, but also related to the production process, coating formula and other factors. Therefore, in the production process, it is necessary to strictly control all aspects to ensure the quality and performance of the final product.
