What are the requirements for the base paper of the three heat-proof paper?

The base paper of the three heat-proof paper has certain requirements in the design and selection to ensure the performance and use effect of the overall label. The following is a specific analysis of the requirements of the three heat-resistant paper backing paper:

1. Material requirements

Strength and toughness: The backing paper needs to have a certain strength and toughness to support the entire label structure and prevent breakage or damage during printing, die-cutting, waste discharge and labeling.

Flatness: The base paper should be kept flat, without wrinkles and uneven bumps, to ensure that the label can be evenly heated during the printing process to avoid print quality problems.

2. Surface treatment

Silicon coating: The surface of the base paper usually needs to be coated with a layer of silicone oil (also known as silicon coating) to reduce the adhesive force between the base paper and the surface material, so that the base paper can be easily removed after labeling without damaging the printed content on the surface material. The uniformity and thickness of silicon coating have important influence on the stripping performance.

3. Dimensional stability

Accurate size: The size of the backing paper needs to be precisely controlled to ensure an accurate match with the surface material to avoid deviations during the die cutting process.

Environmental adaptability: The backing paper should maintain good dimensional stability under different environmental conditions (such as temperature and humidity changes) to prevent printing or labeling problems caused by size changes.

4. Environmental protection

Environmentally friendly materials: With the improvement of environmental awareness, more and more industries require the use of environmentally friendly materials. Therefore, the base paper of the three heat-resistant paper should also be made of environmentally friendly materials to reduce pollution to the environment.

5. Specific application requirements

Back paper color: the color of the back paper is usually white, blue, etc., the specific choice can be based on the actual application scenario and personal preference. For example, in some cases, contrasting backing paper may be selected to better identify label edges.

Thickness and weight: The thickness and weight of the base paper also need to be selected according to the specific needs. Thicker backing paper may provide better support, but may also increase the overall cost; Lighter backing paper may be easier to handle and store.

In summary, the base paper of the three heat-proof paper has certain requirements in terms of material, surface treatment, dimensional stability, environmental protection and specific application needs. These requirements are designed to ensure the overall performance and use effect of the label to meet the needs of different industries and application scenarios. It is recommended to take the above factors into consideration when choosing three thermal paper, and consult professional suppliers for more detailed information and advice.
