Basic concept of BOPP thermal synthetic paper

BOPP thermosensitive synthetic paper is a special paper that combines BOPP (bidirectional tensile polypropylene film) substrate and thermal sensing technology. The following is a detailed explanation of the basic concepts of BOPP thermal synthetic paper:

Definition and constitution

Definition: BOPP thermosensitive synthetic paper is a paper made of BOPP film as a substrate and coated with a heat-sensitive material containing a thermosensitive agent. This paper, through thermal printing technology, can quickly produce images or text when heated, without the use of ink or ribbon, thus achieving fast and instant printing results.

Substrate: BOPP film has high tensile strength, impact strength, rigidity, toughness and good transparency, is the ideal substrate choice. BOPP film is treated by bidirectional drawing process, which makes its molecular chain arrangement more orderly, thus improving the physical properties and chemical stability of the material.

Heat sensitive materials: This is a key part of achieving heat sensitive printing, which contains chemicals that have heat sensitive agents, usually in the form of microcapsules or dyes. When the thermal print head applies heat to the paper, the thermal agent will rapidly undergo a chemical reaction, resulting in a color change, resulting in the formation of a color image or text on the paper.

Physical characteristics

Light weight: The lightweight nature of BOPP film makes this synthetic paper easy to carry and transport.

Good dimensional stability: The molecular chains of the BOPP film are orderly arranged during the bidirectional stretching process, making the paper not easy to deform.

High mechanical strength: excellent tear strength and bending fatigue resistance.

Good transparency: The high transparency of the BOPP film allows the paper to clearly display the background of the image or text before being subjected to thermal sensitivity.

High gloss: The gloss of BOPP film is usually greater than 85%, which makes the paper present a high-grade and attractive visual effect during printing and use.

Rapid thermal response: The thermal coating on the surface can quickly produce color images or text when heated.

Bright colors: The special formulation and process of the heat-sensitive coating makes the printed colors bright and long-lasting.

Environmental protection and non-toxic: BOPP film and thermal coating materials meet the requirements of safety and environmental protection, non-toxic, odorless, tasteless, suitable for applications in direct contact with food and drugs.

Moisture resistance and wear resistance: BOPP film has excellent moisture resistance and wear resistance, which can protect the packaging from moisture attack and extend the service life.

Application field

Because of its special materials and characteristics, BOPP thermal synthetic paper is widely used in many fields, including but not limited to:

Receipt printing: Printing shopping receipts and receipts in retail places such as supermarkets and convenience stores.

Label printing: Printing various labels in terms of commodity pricing, inventory management, etc.

Express sheets: Print express sheets in the express delivery and logistics industry to ensure the accuracy and readability of information during transportation.

Medical records: Printing various medical records, prescriptions and test reports in hospitals and clinics.

Office printing: Printing various internal documents, reports and meeting materials in an office environment.

Food and entertainment: Print menus, orders and coupons in restaurants, bars and entertainment venues.

Personalized customization: Make personalized gift packaging, business cards and greeting cards.

Technological innovation

The technical innovation of BOPP thermal synthetic paper is mainly reflected in the following aspects:

Material formulation and production process optimization: By optimizing the polymer material formulation and bidirectional drawing process, the physical properties and chemical stability of the material are improved.

Thermal coating technology improvement: Continuously optimize the coating formula to improve the sensitivity, stability and color brightness of the thermal coating.

Coating and printing technology: The use of wet coating, gravure coating, reverse coating and other advanced coating technology to ensure the quality and stability of the coating; At the same time, with the development of high-precision printing technologies such as digital printing and flexographic printing, synthetic paper is more handy in printing complex patterns and texts.

Functional development: On the basis of heat-sensitive coatings, multi-functional coatings are further developed, such as anti-scratch wear-resistant coatings, antibacterial coatings, anti-static coatings, etc., to meet the needs of different fields.

In summary, BOPP thermal synthetic paper is a special paper combining BOPP film substrate and thermal induction technology, with excellent physical properties and chemical stability, good printing adaptability and a wide range of applications. With the continuous progress of technology and the increasing market demand, its application prospects will be broader.
