What do you need to pay attention to when buying color thermal label paper?

When purchasing color thermal label paper, you need to pay attention to the following key issues to ensure that the purchase of high-quality products that meet the demand:

First, quality and durability

1. Temperature range:

Select the appropriate temperature range according to the specific use environment. For example, if the label will be used in a high temperature environment, you should choose a label paper with strong high temperature resistance.

2. Waterproof, oil and alcohol proof properties:

Color thermal label paper usually has certain waterproof, oil-proof, and alcohol-proof properties, but the performance of different products may vary. Select products with corresponding performance based on actual requirements.

3. Print quality and clarity:

Choose label paper with high print quality and good clarity to ensure that the printed text or bar code is easy to identify.

Second, appearance and coating quality

1. Paper color:

Observe the color of the paper and choose a slightly greenish paper. Too white paper may add too much phosphor, affecting the quality of the coating.

2. Coating uniformity:

Check whether the surface of the paper is smooth and flat, and whether the coating is uniform. Uneven coating may result in different color shades when printing, affecting print quality.

Third, test and identification methods

1. Sun exposure comparison:

Apply the printed paper with a highlighter and put it in the sun to observe the blackening speed. The faster the blackening speed, the shorter the storage time of the label.

2. Fire test:

Heat the back of the paper with a lighter and observe the color change. The better quality paper should appear black and green after heating, and the color block is uniform. If it appears brown or has small streaks and uneven color patches, the thermal formula or coating quality may be poor.

Fourth, specifications and dimensions

1. Roll width and diameter:

Select the appropriate roll width and diameter according to the actual needs. Pay attention to check whether the actual diameter of the paper roll is consistent with the label to avoid the merchant's shortfalls.

2. Core diameter:

The diameter of the tube core should also be paid attention to, so as not to shorten the length of the paper because the tube core is too large.

Fifth, brand and after-sales service

1. Brand selection:

Choose well-known brands and high-quality products to ensure the printing effect and service life of the label paper. Well-known brands often have better after-sales service and longer warranty periods.

2. After-sales service:

Understand the merchant's after-sales service policy, so that when you encounter problems in the process of use, you can be solved in time.

In summary, when purchasing color thermal label paper, it is necessary to comprehensively consider many aspects such as quality and durability, appearance and coating quality, testing and identification methods, specifications and sizes, as well as brand and after-sales service to ensure that the purchase of high-quality products that meet the needs.
