What are the types of color thermal label paper?

There are various types of backing paper for color thermal label paper, and these backing papers are different in terms of material, light transmission, process, etc., to meet different application needs. The following is a summary of the types of color thermal label paper backing paper:

First, classification by material

Paper base paper: such as white grid, blue grid, Huang Ge Glasin base paper, these base paper is specially designed for high-speed web printing die cutting and automatic labeling, with good thickness and light transmission.

Film backing paper: such as BOPP (biaxially stretched polypropylene) or PET (polyethylene terephthalate) film backing paper, these backing paper is usually dimensional stability, high strength, and transparent backing paper.

Second, according to the light transmission classification

Transparent backing paper: For example, a plastic film backing paper has high transparency and is suitable for viewing the contents on the back of a label.

Translucent backing paper: such as Glasin backing paper, with a certain degree of light transmission, but not completely transparent.

Opaque backing paper: For example, the surface is coated with plastic backing paper (kraft paper), which is opaque. It is suitable for scenarios where the content on the back of the label needs to be hidden.

Third, according to the process classification

Overpressure backing paper: made by overpressure process, the weight per square meter is usually between 60-80 grams, with good processing performance.

Machined matte backing paper: After machine calendered treatment, the surface is matte, the weight per square meter is between 80-110 grams, opaque.

Fourth, special backing paper

Surface coated plastic bottom paper: a plastic coated silicon bottom paper, the quantity is generally 80-150 grams per square meter, usually yellow and white, opaque, with excellent flatness.

Fifth, common backing paper types

Glasin bottom paper: There are a variety of colors to choose from, such as white, blue, yellow, etc., which is more common in thermal paper. Glasin bottom paper is tight and uniform, strong light transmittance, high temperature resistance and good moisture and oil resistance, widely used in barcode labels, tape and other raw materials.

White thick bottom paper: has excellent flatness, suitable for flat applications, in flat pressing or circular die-cutting equipment has good strength.

In summary, the background paper of color thermal label paper is diverse, and the selection needs to be comprehensively considered according to the specific application scenario, printing equipment, labeling method and cost budget.
