What is the chemical stability of BOPP thermal sensitive synthetic paper?

BOPP thermosensitive synthetic paper has excellent chemical stability, mainly due to its unique material composition and manufacturing process. The following is a detailed analysis of the chemical stability of BOPP thermal sensitive synthetic paper:

1、 The influence of material composition

Polypropylene substrate: BOPP thermosensitive synthetic paper is mainly made of polypropylene (PP), which is a chemically stable plastic with excellent chemical corrosion resistance. It is not easily reacted with common chemicals such as acids, bases, salts, etc., thus ensuring the chemical stability of BOPP thermosensitive synthetic paper in various environments.

Thermal sensitive coating: Thermal sensitive coatings are usually composed of water-based resins, thermal sensitive agents, color developing agents, and sensitizers. These ingredients are carefully selected and proportioned to ensure rapid chemical reactions and color development when heated, while maintaining chemical stability. The use of environmentally friendly materials such as water-based resins also reduces the pollution of coatings to the environment.

2、 Contribution of Manufacturing Process

Biaxially oriented stretching process: The substrate of BOPP thermal sensitive synthetic paper is made of biaxially oriented polypropylene film (BOPP). This process involves stretching in two vertical directions (longitudinal and transverse) to rearrange the molecular chains of the film, forming a highly oriented structure. This structure not only improves the transparency and glossiness of the film, but also significantly enhances its tensile strength, impact strength, and rigidity, thereby helping to improve chemical stability.

Advanced coating technology: using advanced coating technologies such as wet coating, gravure coating, reverse coating, etc., the thermosensitive coating is uniformly coated on the surface of BOPP substrate. These technologies have advantages such as simple equipment, low processing costs, and suitability for large-scale production, ensuring the quality and stability of coatings.

3、 Performance of chemical stability

Chemical resistance: BOPP thermosensitive synthetic paper can resist the erosion of various chemicals, such as acid, alkali, salt, etc. This chemical resistance enables it to maintain stable performance in various complex environments.

Long term stability: BOPP thermosensitive synthetic paper can maintain its physical and chemical stability during storage and use. Even under prolonged exposure to specific environmental conditions such as high temperature, high humidity, etc., it can maintain good performance.

4、 Application Fields

Due to its excellent chemical stability, BOPP thermosensitive synthetic paper has been widely used in multiple fields. For example, in the retail industry, it is often used as receipt paper; In the logistics industry, it is used as label paper; In the catering industry, it is used for printing orders, etc. These application areas require paper to have good chemical stability to ensure the accuracy and durability of information.

In summary, BOPP thermosensitive synthetic paper has excellent chemical stability, thanks to its unique material composition and manufacturing process. This stability enables it to maintain stable performance in multiple fields and meet various application requirements.
