In the winter, various problems often occur with adhesive label paper, especially on plastic bottles, when the temperature is low, warping, blistering, and wrinkling occur. This is especially noticeable for labels with large area sizes attached to curved surfaces. So, how do we solve the problem of foaming of the sticker in the winter?
There are many reasons for this. The following are introduced one by one.
1. If the label material is paper, there is no shrinkage and expansion performance with temperature change;
2. The viscosity of the adhesive used for the label is small, and it cannot be firmly combined with the object;
3. When attaching a label, there is a gap between the label and the object to be attached. Water and gas can also cause these situations;
4. The surface factors of the object to be pasted, for example, the object to be pasted is spherical, and some shapes are difficult to post. There are oil stains and irregular particles on the surface.
5. Storage conditions after labeling. In some individual cases, the label meets the requirements, but it is not stored in the correct storage environment, which causes the label to blister and fall off.
solution:
1. Select materials suitable for labeling in low-temperature winter environments, such as special labels that are resistant to low temperatures. Powerful companies can use self-adhesive labels made of PE materials.
2. The storage and labeling environment of the label should be performed in the environment of 15 degrees or more in winter. After the label is attached, it should be stored in the 15 degree environment for 24 hours before moving to other temperature environments.
3. Use a small label area, and choose a flat, clean and tidy part for labeling.
