In a cold environment, the viscosity of the sticker decreases as the temperature decreases. Therefore, the following five points should be paid attention to when using self-adhesive labels in winter:
(1) The temperature should not be too low.
When the sticker is placed outdoors or in a cold environment, it is easy to cause frostbite to the material, especially the glue part. If not properly restored, the sticker will lose its stickiness. Therefore, the greenhouse for storing label paper is too low.
(2) Preprocessing
It is very important to pre-process adhesive labels in cold regions. If the temperature of the self-adhesive trademark on the label paper is too low and frostbite due to the inability to meet the required transportation and storage conditions, even if the label environment temperature meets the requirements, the adhesion of the self-adhesive label will decrease. Affected by the inability to recover in time. Therefore, in the above cases, before the labeling operation, the self-adhesive label paper should be placed in the label environment for a period of time to restore and restore the temperature of the material;
(3) control marking temperature.
The sticker temperature is the lowest ambient temperature at which you can operate. The use temperature of the self-adhesive label refers to the applicable ambient temperature range when pasted on the pasted surface (usually 24 hours). After the label temperature is normal, the self-adhesive label can be used within this temperature range. Any type of self-adhesive material has a related labeling temperature, and the viscosity of the self-adhesive label is lower than the temperature of the self-adhesive label, which will cause the label paper and box to warp;

(4) Clean Sticker Surface
Proper label pressure ensures the pressure-sensitive characteristics of the label. At the same time, it can eliminate the air between the adhesive label and the surface. In order to make the registered trademark firm and smooth, the surface cleanliness is also an important factor to ensure adhesion and smoothness.
There are three main types of surface cleaning:
1. There are water droplets, mist and impurities on the surface of the sticker;
2. There is oil or solution on the surface of the sticker;
3. There is a release on the pasted object Agent;
(5) Do not move after labeling
After the label is applied, it usually takes some time to reach the peak. The container or product just placed on the label paper is not suitable for placement in an environment with a large temperature difference. Otherwise, the glue will be affected. Due to temperature changes, thin film labels and containers will heat up and shrink, and self-adhesive labels are more likely to appear when wet or dehydrated. These changes are not conducive to the optimal adhesive properties of the glue.

Break down technical barriers! China's inkjet print head can no longer rely on foreign technology
A few days ago, the ZTE incident came to life after a storm. This crisis without gunpowder smoke has triggered a discussion among Chinese people about independent core technologies. In fact, in the 3D printing industry, there are many domestic technology subject to foreign, piezoelectric inkjet print head is one of them. China's "storm" strong counter-attack piezoelectric inkjet print head in the sand 3D printer, as the chip in the semiconductor, the importance is self-evident. Previously, companies such as German Voxeljet and Exone in the United States have already had relatively mature commercial applications in sand mold 3D printing technology, while Chinese companies limited to nozzles have few brands.

Digital printing will cross the label, rapid development in all areas of packaging
Mr. MichaelFairley believes that label processors still have time to find new business opportunities in the production of flexible packaging and folding cartons with their understanding, expertise and skills in digital printing. At the 2019 Asia International Label Printing Exhibition (LabelexpoAsia2019) held at the Shanghai New International Expo Center from December 3 to 6 this year, about 30 digital printing equipment-related manufacturers participated in the exhibition, including: u.S. Amica (Amica), Domino, Dilli, Haotian, Konica Minolta, Runtianzhi, Yunbo (Shanghai) Internet of Things Technology, Changzhou Temine, Hefei Runjie, Nebula Computer (GCC), Hanhua Industry, Saikang, Zhuo Jue, Dragan and Ningbo Worry, etc. Among these exhibitors, the use of inkjet technology accounts for the vast majority, thanks to the rapid development of nozzle technology, the improvement of printing materials and ink formulations, and the unprecedented progress made by color inkjet printers in terms of performance and market applications. The development of digital printing in the label industry has been more than 20 years. The first to enter this field was toner technology, followed by inkjet technology, and now Landa's nano digital printing technology. This is 20 years of rapid development. So far, the global label industry has installed about 4500 digital printing machines, of which HPIndigo and Saikang toner printing machines account for more than 2/3 of the total installed capacity.
