How does BOPP Thermal synthetic paper work?

The working principle of BOPP thermal synthetic paper is mainly based on the application of thermal technology and color materials, and its detailed working mechanism can be summarized as follows:

Basic composition

BOPP thermal synthetic paper mainly consists of two main parts:

Base material: Biaxial polypropylene (BOPP) film, which is a special process of polypropylene material, has good physical properties and chemical stability.

Thermal coating: A special coating applied to the surface of the BOPP film that contains chemicals such as leucochromic dyes, developing agents and sensitizers. These chemicals remain colorless at room temperature, but when stimulated by a certain temperature, chemical reactions occur and produce color.

Working principle

1.Heating trigger: When the BOPP thermal composite paper passes through the thermal printer, the printer's heating print head will heat a specific area on the paper.

2.Chemical reaction: Heating causes a chemical reaction between the leach dye and the developing agent in the thermal sensitive coating. When heated, the leach dye can react with other chemicals in the coating (such as color developers) to produce colored compounds.

3.Color display: These colored compounds appear on the paper to produce the desired text or image. The type and formulation of the leach dye determines the final color type and effect.

Technical characteristics

No ink or ribbon required: Unlike traditional inkjet or laser printers, BOPP thermal synthetic paper does not use ink or ribbon, reducing the cost of use and maintenance.

Instant printing: Due to the rapid thermal reaction, BOPP thermal synthetic paper can achieve instant printing and improve work efficiency.

Bright colors: By optimizing the formulation and processing of thermal coatings, you can ensure that the printed image or text is bright and clear.

Application field

Due to its unique working principle and technical characteristics, BOPP thermal synthetic paper is widely used in many fields, including but not limited to:

Retail and supermarket: used to print shopping receipts, settlement documents, etc.

Logistics and express: for printing express bills, labels, etc.

Medical and testing: Used to print medical records, testing reports, etc.

Office and business: Used to print various internal documents, reports and conference materials.

Dining & Entertainment: For printing menus, orders, coupons, etc.

Matters needing attention

Temperature control: In order to ensure print quality and extend the life of the paper, it is necessary to control the heating temperature and printing speed of the printer.

Storage conditions: BOPP thermosensitive synthetic paper should be stored in a dry, cool environment to avoid high temperature and humidity resulting in paper deterioration or fading.

Environmental protection and safety: When selecting and using BOPP thermal synthetic paper, attention should be paid to its environmental protection and safety, and products that meet relevant standards and regulations should be selected.

In summary, BOPP thermal synthetic paper achieves instant printing without ink or ribbon through chemical reactions in the thermal coating when heated and produces color. Its unique working principle and technical characteristics make it widely used in many fields.
