In general, the stickiness of tags is good, but in winter when the temperature is low, the sticker's stickiness will also be directly affected. The stickiness of the adhesive label decreases with decreasing temperature, especially on cold snow days.
Storage sticker should pay attention to the problem
1, label storage environment temperature should not be too low. The non-drying compound is placed in the outdoor or cold environment, which can easily cause frostbite of the material, especially the compound. If the recovery is improper, the tackiness and workability of the adhesive will be lost or lost.
The processing environment temperature is very important for the smooth processing of materials. If the temperature is too low, the viscosity of the material will decrease, and there will be poor printing, die cutting scrap, flying marks, drop marks and other phenomena during the processing, which will affect the smooth processing of the material.
3. sticker The ambient temperature of the label should meet the product requirements. Any non-adhesive material has a storage temperature. At this temperature, the adhesiveness of the non-adhesive material is limited, which will cause problems such as improper labeling and warping.
4. Labels Pretreatment is very important in cold regions. If the transportation and storage conditions cannot meet the requirements, the temperature of the label itself will be low, or even frostbite. Although the ambient temperature of the label meets the requirements, the stickiness and processing performance of the label cannot be restored in time. Performance can also be affected. Therefore, in the above case, before the processing or labeling operation, the label material should be placed in the labeling environment for more than 24 hours in advance, so that the temperature of the label material itself is increased, thereby recovering the adhesion and processing properties.
5. After labeling, the stickiness of the sticker material usually takes a period of time (usually 24 hours) to gradually reach a large value. It is not recommended to immediately place the container or product that has just been labeled in an environment with a large temperature difference (even if the environment meets the temperature range for using non-drying adhesive materials). Otherwise, it will affect the development of glue viscosity. In addition, thin film labels and containers expand and contract due to temperature changes, while paper labels are more likely to damp or dehydrate the paper fibers. These changes are detrimental to the good labeling properties of the glue.
Attention should also be paid to label pressure control and surface cleaning. Proper label pressure can not only ensure the pressure sensitivity of the label, but also exhaust the air between the label and the surface, making the label firm and flat. Cleaning the surface is also an important factor in ensuring the stickiness and smoothness of the label.
Storage should pay attention to avoid the cold weather on the dry adhesive label stickiness. At the same time, appropriate moisture-proof and waterproof measures should be taken to avoid storing dry adhesive labels in a humid environment.

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.
