What are the characteristics of the production process of BOPP color thermal sensitive synthetic paper?

The production process characteristics of BOPP color thermal sensitive synthetic paper are mainly reflected in the following aspects:

1、 Raw material selection and formula optimization

Raw material selection: BOPP color thermosensitive synthetic paper is mainly made of polypropylene (PP), which has the advantages of light weight, non-toxic, odorless, moisture-proof, etc.

Formula optimization: By optimizing the formula of polymer materials, the physical properties and chemical stability of the materials can be improved, enabling synthetic paper to maintain its original advantages while also possessing superior mechanical strength, airtightness, and barrier properties.

2、 Bidirectional stretching process

Process: BOPP color thermosensitive synthetic paper is prepared using a biaxial stretching process to produce BOPP film, which involves stretching in two vertical directions (longitudinal and transverse).

Process characteristics:

The molecular chains of the stretched film are rearranged to form a highly oriented structure, which helps to improve the transparency and glossiness of the film.

Bi directional stretching significantly enhances the tensile strength, impact strength, and rigidity of the film, resulting in better physical properties of synthetic paper.

3、 Thermal sensitive coating coating

Coating composition: BOPP colored thermosensitive synthetic paper is coated with a thermosensitive coating composed of water-based resin, thermosensitive agent, color developer, and sensitizer on the surface of BOPP substrate.

Coating technology: Advanced coating techniques such as wet coating, gravure coating, and reverse coating are used to ensure that the thermosensitive coating is evenly coated on the surface of the BOPP substrate.

Coating optimization: By continuously optimizing the coating formula, the sensitivity, stability, and color vividness of the thermosensitive coating are improved, ensuring that the printed image is clearer and more delicate.

4、 Environmental Protection and Sustainability

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.

Recyclability: BOPP color thermosensitive synthetic paper pays attention to environmental protection and sustainability in the production and use process. Its material can be recycled and reused, which meets the requirements of modern green packaging and environmental protection concepts.

5、 Post processing and functional expansion

Post processing technology: BOPP color thermosensitive synthetic paper may require film coating treatment after printing to improve its durability and aesthetics. The selection of laminating materials and the implementation of laminating processes will have an impact on color reproduction and paper performance.

Functional expansion: On the basis of thermal sensitive coatings, multifunctional coatings can be further developed, 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.

In summary, the production process of BOPP colored thermosensitive synthetic paper has the characteristics of raw material selection and formula optimization, biaxial stretching process, thermosensitive coating coating, environmental protection and sustainability, as well as post-treatment and functional expansion. These characteristics make BOPP color thermosensitive synthetic paper have excellent physical properties, chemical stability, and environmental performance, while meeting the needs of different fields for functional, intelligent, and high-quality paper.
