How should thermal paper self-adhesive labels be stored effectively?
Thermal paper self-adhesive label is one of the barcode labels. The surface paper of this type of label is a paper material that has been treated with a high heat-sensitive thermal coating. There is glue behind the printing paper for sticking and fixing. The bottom is a layer of backing paper, which is used to maintain the adhesive. After printing, tear off the backing paper and apply it. The backing paper is generally divided into blue, white and gradation. The general thermal paper is not moisture-proof or resistant. Oily, tearable. So, how long does thermistor label paper last? What's the save FAQ?
Thermal paper is professionally used for label printers and thermal printers. The quality of thermal paper can directly affect the printing effect and storage time, and even affect the service life of copiers and printers.
Thermal paper is generally divided into three layers, the bottom layer is the paper base, the second layer is the thermal coating, and the third layer is the protective layer. The key to the quality of the thermal paper is the thermal coating or protective layer. The uneven coating will cause the printing to be dark in some areas and light in some areas, and the printing effect will be significantly reduced. It has become very short. At this stage, the best thermistor label paper can ensure an expiration date of more than 30 years, and the poor one is only valid for 1-3 months. Relatively good thermal printing paper can be stored for at least 2 years. -5 years.
We all know that the storage time of thermal paper is limited. If it is stored for too long, the adhesive will be ineffective, and the drying will lose its viscosity. Unscientific preservation methods will speed up the process. Thermal paper storage should pay attention to the following aspects:
1. The thermal paper should avoid direct sunlight, waterproof, sunscreen isolation, high temperature and low temperature protection.
2. After the printed labels are packaged, they should be stacked in layers, and should not be too heavy to prevent the super glue from infiltrating and sticking.
3. It can be stored for one year at 23±2℃ and RH65±5% air humidity, and some super glue can reach two years.
4. When the thermal paper is stored, it should be packed with waterproof paper or plastic film with good sealing performance. It should be deposited upright when rolled up. The flat sheet should be stored flat, and the height-to-width ratio of each board should not exceed 1m, and the goods should be off the ground ( wooden board) above 10cm.
5. The label should have an outer box. It is recommended that the plastic film be sealed and packaged again after each use. It can also be given a good storage standard for the label.
