The thermosensitive material of BOPP (biaxially oriented polypropylene) thermosensitive synthetic paper mainly contains chemical substances with thermosensitive agents, which usually exist in the form of microcapsules or dyes. The following is a detailed explanation of BOPP thermal sensitive synthetic paper thermal sensitive materials:
1、 The basic composition of thermosensitive materials
Thermal sensitive materials are a key component of BOPP thermal sensitive synthetic paper for achieving thermal printing. It is mainly composed of chemical substances such as leuco dyes (also known as colorless dyes) and colorants. These substances remain stable at room temperature and do not undergo color reactions. But when the paper encounters a heated print head or other heat source, the temperature in the local area of the coating rapidly increases, causing the latent dye and color developer to melt and undergo a chemical reaction. Under the catalytic action of the chromogenic agent, the structure of the latent dye changes, resulting in the appearance of color. As the temperature decreases, the color reaction is completed and the color is fixed on the paper, forming the desired image or text.
2、 Characteristics of thermosensitive materials
Rapid color development: BOPP thermal sensitive synthetic paper has a very rapid thermal reaction and can complete the color development reaction in a short time, making it suitable for occasions that require rapid printing and marking.
Colorful: Due to the special formula and processing of heat sensitive materials, the color produced by the color reaction is bright and long-lasting, which can meet the needs of various application scenarios.
Environmental friendliness: Thermal sensitive materials emphasize environmental protection and sustainability in their production and use, meeting the requirements of modern green packaging and environmental protection concepts.
3、 Application of thermosensitive materials
BOPP thermal sensitive synthetic paper is favored by the market due to its excellent thermal sensitivity performance and wide application fields. It is commonly used for instant printing of receipts, labels, receipts, restaurant orders, and packaging and decorative materials that require bright and fast printing. In these applications, thermosensitive materials can ensure that paper quickly produces clear and vivid images and text when heated, thereby improving work efficiency and document management convenience.
In summary, the thermal sensitive material of BOPP thermal sensitive synthetic paper is a special coating containing chemical substances such as latent dyes and color developing agents. This coating can quickly undergo chemical reactions and develop color when heated, with characteristics such as rapid color development, bright colors, and environmental friendliness. It has been widely applied in multiple fields and continuously improved and enhanced with the continuous development of technology.
