What are the technical innovations of BOPP color thermal synthetic paper?

The technical innovation of BOPP color thermal synthetic paper is mainly reflected in the following aspects:

First, material formula and production process

1. Polymer material optimization:

BOPP color thermosensitive synthetic paper takes polypropylene (PP) as the main raw material. By optimizing the formula of polymer material, the physical properties and chemical stability of the material are improved. This makes the synthetic paper maintain the advantages of light weight, non-toxic, odorless, moisture-proof and so on, but also has better mechanical strength, air tightness and barrier property.

2. Bidirectional drawing process:

The BOPP film is prepared by bidirectional drawing process, that is, it is stretched in two vertical directions (longitudinal and transverse), so that the molecular chain of the film is rearranged to form a highly oriented structure. This process not only improves the transparency and gloss of the film, but also significantly enhances its tensile strength, impact strength and rigidity.

Second, heat sensitive coating technology

1. Thermal coating formulation innovation:

BOPP color thermal synthetic paper is coated on the surface of BOPP substrate with a heat-sensitive coating composed of water-based resin, thermal sensitive agent, color developing agent and sensitizer. Through continuous optimization of coating formulation, the sensitivity, stability and color brightness of the thermal sensitive coating are improved, making the printed image more clear and delicate.

2. Environmental protection and durability:

In the thermal coating technology, attention is paid to the application of environmentally friendly materials, such as the use of water-based resins and other environmentally friendly materials instead of traditional solvent-based materials, reducing environmental pollution. At the same time, by improving the coating formula and production process, the water resistance, oil resistance, chemical resistance and wear resistance of the synthetic paper are improved, and the service life is extended.

Third, coating and printing technology

1. Advanced coating technology:

The thermal sensitive coating is uniformly coated on the surface of BOPP substrate by using advanced coating technologies such as wet coating, gravure coating and reverse coating. These technologies have the advantages of simple equipment, low processing cost, and suitable for large-scale production, ensuring the quality and stability of the coating.

2. High precision printing technology:

BOPP color thermal synthetic paper has good printing adaptability, and can be printed with color to obtain exquisite appearance. With the development of high-precision printing technology such as digital printing and flexographic printing, synthetic paper is more convenient for printing complex patterns and text.

Fourth, functional expansion

1. Multifunctional coating development:

On the basis of heat-sensitive coating, further development of multi-functional coating, such as anti-scratch wear-resistant coating, antibacterial coating, anti-static coating and so on. With the addition of these functional coatings, BOPP color thermal synthetic paper has more special functions while maintaining the original advantages, and meets the needs of different fields.

2. Intelligent application:

With the development of the Internet of Things and intelligent technology, BOPP color thermal synthetic paper can also be combined with RFID, NFC and other smart label technology 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 technical innovation of BOPP color thermal synthetic paper involves many aspects such as material formulation and production process, thermal coating technology, coating and printing technology, 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.
