Quality standard for BOPP color thermal synthetic paper

BOPP color thermal synthetic paper quality standards involve many aspects, the following is a detailed summary of its quality standards:

First, appearance quality

1. Color and uniformity:

The color of BOPP color thermal synthetic paper should be uniform and bright, without obvious color difference or color spots.

2. Surface flatness:

Paper surface should be flat, smooth, no obvious uneven phenomenon.

3. Impurity control:

The paper should not contain obvious impurities or foreign bodies.

Second, physical properties

1. Thickness:

The thickness of BOPP color thermal synthetic paper should be controlled within a certain range, the common thickness range is usually 55-80 microns, the specific thickness according to the application needs.

2. Dryness:

The dryness of the paper should be moderate, neither too wet to lead to a decline in print quality, nor too dry to affect the flexibility and service life of the paper.

3. Tensile strength and elongation at break:

BOPP color thermal synthetic paper should have a certain tensile strength to ensure that it is not easy to break during use. At the same time, the elongation at break should be moderate to facilitate subsequent processing and use.

Third, thermal sensitivity

1. Hair color principle:

The color principle of BOPP color thermosensitive synthetic paper is based on a thermochromic layer that produces chemical changes at specific temperatures, thus displaying clear text and images.

2. Print quality:

The paper should be able to adapt to various common models of thermal printers to ensure the stability and consistency of the printing effect. Printed text and images should be clear, not faded or blurry.

3. Ink absorption:

The paper should have good ink absorption and be able to absorb the ink transmitted by the printer in time to ensure the printing quality.

Fourth, durability

1. Light stability:

BOPP color thermal synthetic paper should have a certain degree of light stability, and it is not easy to change color or fade under long-term sun exposure.

2. Thermal stability:

Paper in high temperature environment should maintain stability, not easy to deformation or deterioration.

3. Humidity stability:

In an environment with large humidity changes, the paper should maintain stability to avoid a decline in print quality due to too high or too low humidity.

4. Aging resistance:

The paper should have a certain anti-aging property, and it is not easy to produce yellowing or embrittlement in long-term use.

Fifth, environmental standards

1. Material selection:

The main components of BOPP color thermal synthetic paper should be non-toxic, environmentally friendly and degradable materials.

2. Production process:

The production process should meet the requirements of environmental protection and reduce the pollution to the environment.

3. Disposal:

Waste thermal paper should be classified to minimize the adverse impact on the environment.

In summary, the quality standards of BOPP color thermal synthetic paper involve many aspects such as appearance quality, physical properties, thermal properties, durability and environmental protection standards. The formulation and implementation of these standards are essential to ensure the quality stability and application effect of BOPP color thermal synthetic paper.
