How To Use Self-adhesive Labels And Storage Requirements
Storage requirements for self-adhesive labels:
1. Self-adhesive labels should be protected from direct sunlight, moisture-proof, sun-proof, high-temperature and ultra-low temperature.
2. Self-adhesive labels cannot be mixed with flammable and volatile dangerous goods.
3. The self-adhesive labels should be packed and sealed with moisture-proof paper or film. The rolls should be stacked upright, and the flat sheets should be stored flat. The height of each board should not exceed 1m, and the goods should be more than 10cm from the ground (wooden board).
4. It can be stored for one year at 23±2℃ and RH65±5% relative humidity, and some glues can reach two years.
Analysis of common problems of self-adhesive labels:
1. The choice of permanence and removability of self-adhesive label paper According to the performance of adhesives, it can be divided into two categories: permanent adhesives and removable adhesives. (Permanence is generally used in electronic machinery, such as electronic labels, typical: mobile phone battery labels, removability is generally used in food, personal care, etc., such as: wet tissue labels, fruit labels, labels on clothes, etc.) and other products that need to be removed.
2. Self-adhesive label paper may be attached to the surface of various materials, such as glass, metal, cardboard and plastic. And plastics can be further divided into: polyvinyl chloride, high density polyethylene. Tests have shown that different label surfaces have the greatest impact on performance, and we must pay attention to the material of the label surface when choosing.
3. Intuitively, a rough label surface requires a glue with a stronger viscosity, on the contrary, you can choose a glue with a weaker viscosity.
4. The surface shape of the item to be labeled is divided into flat and curved surfaces. If the label surface has a certain curvature (for example, the surface of a medicine bottle with a diameter of less than three centimeters), the label surface material may be required to have good fit, or there are Strong viscosity glue. It is also necessary to choose materials with better flexibility and stretch resistance, such as PVC. If the surface of the labelled item is flat, the material to be labelled is more suitable, and if the surface of the labelled item is not flat, the choice of material is much smaller.
5. The cleanliness of the surface of the self-adhesive label paper. The self-adhesive material is most suitable for the surface of the surface to be clean, dry, and free of oil and dust. (When any labeling, it is necessary to keep the surface of the object dry, free of oil and dust, so as to achieve the best labeling effect, if the surface cleaning is poor, it will first affect the stickiness of the self-adhesive label paper)
