How to ensure the dimensional accuracy of transparent thermal label paper?

To ensure the dimensional accuracy of transparent thermal label paper, you can start from the following aspects:

1. Select high-precision production equipment

Advanced coater: High precision coater equipment is used to ensure uniform and accurate coating of thermal sensitive coatings on the substrate. The high precision coating machine can control the thickness and width of the coating, which directly affects the final size of the label paper.

Cutting and coiling equipment: High-precision cutting and coiling equipment is used to ensure that the size of the label is accurate during the cutting process, and that the label paper is kept flat during the winding process to avoid deformation.

2. Strictly control the production process parameters

Coating speed: According to the performance of the coating machine and the characteristics of the thermal coating, the appropriate coating speed is set to ensure the uniformity and stability of the coating, and then ensure the dimensional accuracy of the label paper.

Drying conditions: During the drying process, strictly control the temperature, humidity and drying time in the oven to ensure that the heat-sensitive coating can be fully cured and not deformed, so as to maintain the dimensional accuracy of the label paper.

Cutting accuracy: By adjusting the sharpness of the cutting blade, cutting speed and cutting pressure and other parameters, to ensure that the cutting accuracy meets the requirements and avoid dimensional deviation.

3. Implement strict quality inspection and control

Online detection: The online detection equipment is installed on the production line to carry out real-time dimensional detection of the label paper in the production process, and timely find and correct the dimensional deviation.

Sampling inspection: Regular sampling inspection of the production batch to measure key dimensions such as the width and length of the label paper to ensure compliance with customer requirements and industry standards.

Data analysis and feedback: Statistical analysis of the test data, find out the causes and rules of size deviation, timely adjust the production process parameters and equipment status to improve the size accuracy.

4. Strengthen raw material management

Raw material quality control: Strict quality testing and control of purchased substrates and thermal coatings to ensure that the dimensional accuracy and stability of raw materials meet production requirements.

Storage and custody: Proper storage and custody of raw materials to avoid moisture, deformation or pollution and other factors affecting its dimensional accuracy.

5. Staff training and skill improvement

Regular training: Regular skills training and safety education for production operators to improve their operational skills and quality awareness to ensure accurate implementation of production process requirements.

Incentive mechanism: Establish an incentive mechanism to encourage employees to actively participate in quality improvement and innovation activities, and improve their attention and enthusiasm for dimensional accuracy control.

In summary, through the selection of high-precision production equipment, strict control of production process parameters, the implementation of strict quality testing and control, strengthening raw material management and staff training and skills improvement and other measures, we can ensure that the dimensional accuracy of transparent thermal label paper meets the requirements.
