The technological innovation of BOPP color synthetic paper (especially BOPP color thermosensitive synthetic paper) is mainly reflected in the following aspects:


1、 Innovation in Material Formula and Production Process

Raw material optimization: BOPP color synthetic paper is mainly made of polypropylene (PP), and the physical properties and chemical stability of the material are improved by optimizing the formula of the polymer material. This enables synthetic paper to maintain its advantages of being lightweight, non-toxic, odorless, and moisture-proof, while also possessing superior mechanical strength, airtightness, and barrier properties.

Bi directional stretching process: BOPP film is prepared using the bi directional stretching process, which involves stretching in two vertical directions (longitudinal and transverse) to rearrange the molecular chains of the film and form a highly oriented structure. This process not only improves the transparency and glossiness of the film, but also significantly enhances its tensile strength, impact strength, and rigidity.

2、 Innovation in Thermal Coating Technology

Optimization of thermal sensitive coating formula: BOPP colored thermal sensitive synthetic paper is coated with a thermal sensitive coating composed of water-based resin, thermal sensitive agent, color developer, and sensitizer on the surface of BOPP substrate. By continuously optimizing the coating formula, the sensitivity, stability, and color vividness of the thermosensitive coating have been improved, resulting in clearer and more delicate printed images.

Application of environmentally friendly materials: In thermal sensitive coating technology, attention is paid to the application of environmentally friendly materials, such as using water-based resins and other environmentally friendly materials instead of traditional solvent based materials, which reduces environmental pollution.

Multi functional coating development: Based on thermal sensitive coatings, further develop multifunctional coatings such as scratch resistant and wear-resistant coatings, antibacterial coatings, anti-static coatings, etc. The addition of these functional coatings enables BOPP color thermosensitive synthetic paper to maintain its original advantages while also possessing more special functions, meeting the needs of different fields.

3、 Innovation in Coating and Printing Technology

Advanced coating technology: Adopting advanced coating technologies such as wet coating, gravure coating, and reverse coating, 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.

High precision printing technology: BOPP color synthetic paper has good printing adaptability and can achieve exquisite appearance effects through color matching printing. With the development of high-precision printing technologies such as digital printing and flexographic printing, synthetic paper has become more adept at printing complex patterns and text.

4、 Innovation in production equipment

Intelligent control system: The modern BOPP color thermosensitive synthetic paper production line is equipped with advanced intelligent control systems that can monitor various parameters in real-time during the production process, such as temperature, pressure, speed, etc., and automatically adjust them according to preset process requirements to ensure the stability of the production process and consistency of product quality.

Automated production line: By introducing automated production lines, manual intervention is reduced, and production efficiency and product accuracy are improved. The application of technologies such as automatic roll changing, automatic film bonding, and automatic detection makes the production process more efficient and continuous.

Efficient and energy-saving equipment: Adopting new high-efficiency extruders, energy-saving drying systems and other equipment, it reduces production costs and energy consumption, while improving production efficiency and product quality.

5、 Functional expansion and innovation

Application of anti-counterfeiting technology: BOPP colored thermal sensitive synthetic paper can be combined with other anti-counterfeiting technologies, such as fluorescent anti-counterfeiting, temperature change anti-counterfeiting, etc. By adding fluorescent or temperature sensitive materials to these papers, hidden anti-counterfeiting information can be displayed under specific conditions such as ultraviolet irradiation or temperature changes, further improving the anti-counterfeiting effect.

Smart tag technology: With the development of the Internet of Things and smart technology, BOPP color thermal sensitive synthetic paper can also be combined with smart tag technologies such as RFID and NFC to achieve intelligent tracking and management of items. This provides a more convenient and efficient solution for asset management and inventory monitoring in the office field.


In summary, the technological innovation of BOPP color synthetic paper involves multiple aspects such as material formulation and production process, thermal sensitive coating technology, coating and printing technology, production equipment, and functional expansion. These technological innovations not only improve the performance and quality of synthetic paper, but also broaden its application fields and market prospects.
