What are the new materials for BOPP color thermal synthetic paper?

The new materials used for BOPP color thermal synthetic paper mainly include some high performance, environmental protection and special function materials. Here are some specific examples:

1. High Performance polypropylene (PP) substrate:

High molecular weight polypropylene: The use of high molecular weight polypropylene as a substrate can significantly improve the tensile strength, impact strength and toughness of BOPP color thermal synthetic paper.

Modified polypropylene: By adding an appropriate amount of modifier such as toughening agent and nucleating agent, polypropylene is modified to improve its processing performance and the physical properties of the final product.

2. Environmentally friendly additives:

Bio-based additives: Additives made from bio-based raw materials (such as starch, cellulose, etc.) can reduce dependence on fossil resources and reduce carbon emissions in the production process.

Halogen-free flame retardants: Traditional flame retardants may contain halogen elements, which have a certain impact on the environment and human health. Therefore, the development of halogen-free flame retardants and their application in BOPP color thermal synthetic paper can improve the environmental performance of products.

3. Functional coating materials:

Thermal coating material: This is a key component of BOPP color thermal synthetic paper. The new heat-sensitive coating materials should have higher sensitivity, stability and weather resistance to meet the needs of a wider range of applications.

Waterproof and oil-resistant coating: Coating the surface of BOPP color thermal synthetic paper with waterproof and oil-resistant coating can significantly improve its water resistance and oil resistance, suitable for applications requiring high protection performance.

Antibacterial coating: With people's attention to health, antibacterial coating is more and more widely used in BOPP color thermal synthetic paper. This coating material can effectively inhibit the growth and reproduction of bacteria, mold and other microorganisms, and improve the sanitary performance of the product.

4. Other new materials:

Nanomaterials: The introduction of nanomaterials (such as nano-silica, nano-calcium carbonate, etc.) into the production of BOPP color thermosensitive synthetic paper can significantly improve its optical properties, mechanical properties and thermal stability.

Smart materials: With the development of smart packaging technology, some smart materials with special functions are also applied in BOPP color thermal synthetic paper. For example, a temperature-indicating material can change color or transparency at a specific temperature; The humidity indicator material can reflect the humidity change inside the package, etc.

It should be noted that the application of new materials is often accompanied by the adjustment and improvement of production processes and equipment. Therefore, when introducing new materials, companies need to fully consider their compatibility with existing production processes and equipment, as well as cost-effectiveness and other factors. At the same time, with the progress of science and technology and the continuous change of market demand, the application field of new materials will continue to expand and innovate.
