What is the difference between BOPP thermal synthetic paper and PET thermal synthetic paper?

There are significant differences between BOPP thermal synthetic paper and PET thermal synthetic paper in multiple aspects. The following is a detailed comparison of these two materials:

1、 Basic material characteristics

BOPP thermal sensitive synthetic paper

Material: Made of biaxially oriented polypropylene (BOPP) film as the substrate.

Features: Lightweight, high transparency, good glossiness, excellent dimensional stability, high mechanical strength.

PET thermosensitive synthetic paper

Material: Made of polyethylene terephthalate (PET) film as the substrate.

Features: high transparency, good temperature resistance, strong durability, high stiffness, and not easily deformed.

2、 Thermal sensitivity performance

BOPP thermal sensitive synthetic paper

Thermistor reaction: The surface thermosensitive coating can quickly undergo a chemical reaction when heated, producing colored images or text.

Color rendering speed: usually fast, able to meet the needs of instant printing.

PET thermosensitive synthetic paper

Thermal reaction: It also has thermal sensing characteristics, but the specific reaction speed and color development effect may vary depending on the production process and formula.

Temperature resistance: Compared to BOPP, PET has better temperature resistance and can maintain stable printing effects at higher temperatures.

3、 Application scenarios

BOPP thermal sensitive synthetic paper

Applicability: Due to its excellent printing and adhesive properties, it is suitable for various printing methods and has bright and saturated printing effects. In addition, its lightweight, easy to carry and transport characteristics also make it suitable for occasions that require fast printing and marking.

Application areas: Widely used in scenarios that require real-time printing and short-term use, such as cash registers, settlement documents, shopping receipts, logistics labels, etc.

PET thermosensitive synthetic paper

Applicability: Due to its good temperature resistance and durability, it is more suitable for outdoor use or scenarios that require long-term storage.

Application areas: Electrical labels, mechanical product labels, outdoor advertising, product manuals, and other occasions that require weather resistance and long-term clarity.

4、 Cost and Environmental Impact

Cost: BOPP thermal synthetic paper usually has lower costs because polypropylene raw materials are relatively cheap and the production process is relatively simple. Due to differences in raw materials and production processes, the cost of PET thermosensitive synthetic paper may be slightly higher.

Environmental impact: BOPP materials are relatively environmentally friendly in the production process, and the end products can be recycled. PET also has the potential for recycling and reuse, but its specific environmental performance may vary depending on the production process and recycling system.

In summary, BOPP thermosensitive synthetic paper and PET thermosensitive synthetic paper have significant differences in basic material characteristics, thermosensitive performance, application scenarios, as well as cost and environmental impact. When choosing, various factors should be comprehensively considered based on specific application needs and scenarios to select the most suitable thermal sensitive synthetic paper material.
