How to solve the problem of wrinkling of three heat-sensitive labels?

To solve the problem of wrinkling of three heat-sensitive labels, you can start from the following aspects:

First, material selection and optimization

1.Choose high quality thermal paper: ensure that the selected paper has good water, oil and scratch resistance, while having a certain stiffness and flexibility to reduce the possibility of wrinkling.

2.Optimize paper structure: For paper that is prone to wrinkling, you can consider adding reinforcing agents or adjusting fiber distribution during the paper production process to improve the strength and stability of the paper.

Second, labeling environment and operation control

1.Control the labeling environment: keep the temperature and humidity of the labeling environment stable to avoid excessive temperature and humidity changes that may lead to moisture absorption expansion or dry contraction of the paper, resulting in wrinkling. It is generally recommended that the labeling environment be dry and the temperature difference is not much.

2.Correct operation of the labeling equipment: the operator should be familiar with the operation method of the labeling equipment to ensure that the label is evenly stressed during the attaching process to avoid wrinkling caused by improper operation.

Third, label design and processing improvement

1.Reasonably design label size and shape: According to the actual needs of auto parts, reasonably design the size and shape of the label to avoid wrinkles when attaching too large or too small labels.

2.Improved label processing technology: The use of film coating process instead of polishing oil process, can effectively isolate the label to absorb external water, reduce the probability of folding. At the same time, pay attention to the flatness and dimensional stability of the cutting process to ensure that the label is not deformed during the processing.

Fourth, storage and transportation precautions

1.Proper storage: The heat-sensitive label paper should be kept away from moisture and direct sunlight during storage, and stored in a dry, cool and well-ventilated place. At the same time, pay attention to the storage time should not be too long, so as not to reduce the quality of the paper resulting in wrinkling.

2.Careful transportation: During the transportation process, appropriate packaging measures should be taken to prevent the label paper from being squeezed and collided, and to maintain its flatness.

Fifth, solutions to specific problems

1.For wrinkled labels: you can try to use the method of pressing or tapping to smooth the label. But this approach may not work in all cases and has limited effectiveness.

2.For surface labeling such as PET bottles: If the label needs to be attached to a curved object (such as a PET bottle), ensure that the surface of the object is smooth and clean, and select the appropriate adhesive and labeling method to reduce wrinkling.

To sum up, the solution to the problem of wrinkling of heat-resistant label paper needs to start from many aspects, including material selection and optimization, labeling environment and operational control, label design and processing improvement, storage and transportation precautions and solutions for specific problems. Through comprehensive policies, the incidence of label wrinkling can be effectively reduced, and the marking effect and product quality can be improved.
