What are the technological innovations in the BOPP color thermosensitive synthetic paper market?

The technological innovation in the BOPP color thermosensitive synthetic paper market is mainly reflected in the following aspects:

1、 Innovation in material formula and production process

Raw material optimization:

Using polypropylene (PP) as the main raw material, the physical properties and chemical stability of the material have been improved by optimizing the formula of the polymer material.

Synthetic paper not only maintains the advantages of lightweight, non-toxic, odorless, and moisture-proof, but also has superior mechanical strength, airtightness, and barrier properties.

Double directional stretching process:

BOPP film is prepared using biaxial 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 improves the transparency and glossiness of the film, while enhancing its tensile strength, impact strength, and rigidity.

2、 Innovation in thermal coating technology

Optimization of thermal sensitive coating formula:

Coat the surface of BOPP substrate with a thermosensitive coating composed of water-based resin, thermosensitive agent, color developer, and sensitizer.

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 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.

3、 Innovation in coating and printing technology

Advanced coating technology:

Advanced coating techniques such as wet coating, gravure coating, and reverse coating are used to evenly coat the thermosensitive coating 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 colored thermosensitive 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、 Functional expansion and innovation

Multi functional coating development:

On the basis of thermal sensitive coatings, further development of 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.

Combining intelligent tag technology:

With the development of the Internet of Things and intelligent technology, BOPP colored 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 in the BOPP color thermosensitive synthetic paper market involves multiple aspects such as material formulation and production processes, thermosensitive 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.
