What are the performance parameters of color thermal label paper?

The performance parameters of color thermal label paper involve many aspects, which jointly determine the use effect and application range of the label paper. Here are some of the main performance parameters:

1. Basic physical parameters

Gram weight: Indicates the weight of paper per unit area, usually in grams/square meters (g/㎡). The gram weight affects the thickness and stiffness of the paper, which in turn affects the printing effect and durability.

Thickness: The thickness of the paper, usually measured in micrometers (μm). There is a certain correlation between thickness and gram weight, but not an absolute correspondence. Labels of different thicknesses are applicable to different application scenarios.

Dimensional stability: The ability of paper to maintain the same size under environmental changes. Good dimensional stability is particularly important for applications that require precise dimensional control.

2. Thermal performance parameters

Minimum label temperature: The lowest temperature at which the label can be attached. This parameter is particularly important for labels used at low temperatures.

Color density: indicates the depth of the image or text after printing. The higher the optical density, the clearer and more vivid the print effect.

Thermal reaction speed: the speed of color development after the indicator paper is heated. Rapid thermal reaction can improve printing efficiency.

3. Durability parameters

Waterproof: The ability of the label to resist moisture penetration. Waterproof label paper can keep the printing content clear and complete in a humid environment.

Oil resistance: The ability to resist the penetration of grease. This parameter is particularly important for labels that need to be used in an oily environment.

Tear resistance: The ability of the label to resist tearing. Good tear resistance ensures that the label paper is not easily damaged during use.

Shelf life: The length of time that the label paper keeps the printed content clear and complete under certain conditions. The storage life is affected by factors such as ambient temperature and humidity.

4. Other parameters

Adhesive type: Type of adhesive used on the back of the label, such as permanent acrylic emulsion adhesive. Different adhesive types are suitable for different adhesive surfaces and adhesive needs.

Substrate type: The base material of the label paper, such as blue Glasin, etc. The type of substrate affects the overall performance and application scope of the label paper.

Environmental performance: The impact of the label on the environment during production, use and disposal. Label paper with good environmental performance is usually made of non-toxic and degradable materials.

5. Apply relevant parameters

Applicable temperature range: specifies the ambient temperature range within which the label can be used properly. This parameter is particularly important for labels used at extreme temperatures.

Applicable environment: The labels are applicable to specific environments or scenarios, such as direct sunlight, high temperature and high humidity.

Compatibility: The compatibility of the label with different models of thermal printers or printing devices.

It should be noted that different brands and different models of color thermal label paper may have differences in performance parameters. Therefore, the selection of labels should be based on the specific application scenarios and requirements. At the same time, you can also refer to the performance test reports and comparative data published by authoritative agencies or professional websites in order to make a more informed choice.
