How to avoid curling of heat-sensitive label paper?

To avoid the curling of the heat-sensitive label paper, you can start from the following aspects:

First, reasonable storage

1.Humidity control: In the storage process of thermal paper, the humidity is too high or too low, which can easily cause the paper to bend and deform. Therefore, ensure that the humidity of the storage environment is moderate and avoid extreme wet or dry conditions.

2.Proper stacking: Thermal paper should be stored in a way that avoids stacking, because the paper is prone to bending due to gravity. It is recommended to store the paper flat or rolled upright to reduce the risk of bending.

3.Avoid heavy pressure: During transportation and storage, heat sensitive paper should be avoided under heavy pressure, so as not to cause the paper to bend and deform.

Second, optimize the use

1.Printing Settings: When printing heat-resistant label paper, you can adjust the Settings of the printer, such as paper type, printing speed, etc., to adapt to different materials and thickness of the label paper, reducing the possibility of curling.

2.Timely access: The printed label paper should be accessed in time to avoid long-term exposure to air or other external forces, resulting in curling.

Third, physical processing

1.Side hem: For thermal paper that is already slightly crimped, you can try to fold a very thin edge on the side, which helps to alleviate the phenomenon of crimping. However, it should be noted that this method may not be suitable for all cases, and there are certain requirements for the accuracy and strength of the hem.

2.Heavy flattening: Laying the curled thermal paper flat on a flat table, and then gently pressing it down with a book or other heavy object for a while will help to restore the paper to level. But this method may only work with lightly crimped paper.

Fourth, choose the right paper

1.Material selection: When purchasing heat-sensitive label paper, you should choose products with reliable quality and stable material. High-quality paper tends to have better anti-curling properties.

2.Thickness considerations: The thickness of the paper is also an important factor affecting crimp. In general, paper of moderate thickness is less likely to curl. Therefore, when choosing paper, the appropriate thickness should be selected according to the actual needs.

To sum up, avoiding the curling of heat-resistant label paper needs to start from many aspects such as storage, use, physical processing and paper selection. The risk of thermal paper curling can be effectively reduced through reasonable storage, optimized use, appropriate physical treatment and selection of appropriate paper material and thickness.
