High standards, refined, zero defects, high standards, refined, zero defects, is the basic requirements of enterprises for employees, but also the basic working attitude of employees. High standards are prerequisites, refinement is the basic requirement, and zero defects are the ultimate goal. The three are interlocking and indispensable.

The difference between aluminum foil tape and other tape
In recent years, the printing industry has widely used non-toxic water-based ink printing. Aluminum foil tape ink is the only non-toxic ink approved by the American Food and Drug Association in all current printing methods.
Therefore, aluminum foil tape is also known as green tape and is widely used in food and pharmaceutical packaging, which is beyond the reach of other printing methods.
Although the ink layer of the aluminum foil tape is thinner than the gravure printing, it is absolutely thicker than the offset printing, which is very advantageous for large-area color blocks which are common in printing packaging products;
Generally speaking, if the paper condition does not change, the ink color between the same batch of products and different batches of products can be consistent, which is the most basic requirement of packaging printing, and this is also the offset printing method. It is not easy to do.
Aluminum foil tape is made of high-quality pressure-sensitive adhesive, good viscosity, strong adhesion, anti-aging, and good heat preservation function. Therefore, it is often used for the wrapping of cold (hot) gas pipelines, which is very useful in the field of air-conditioning engineering, especially water heater refrigerators. Production is often used.
What are the characteristics of aluminum foil tape?
Aluminum foil tape is made of high quality pressure sensitive adhesive, good adhesion, strong adhesion and anti-aging effect.
Aluminum foil tape is the main raw and auxiliary material of the refrigerator freezer production plant, and is also a must-have raw material for the insulation material distribution department.
The aluminum foil tape is bonded to the joints of all the aluminum foil composite materials, the sealing of the insulation nail puncture site and the repair of the damaged portion.
The insulation performance of aluminum foil tape is greatly improved, and the specifications are (0.05mm-0.08mm)* various widths and lengths.
The difference between aluminum foil tape and other tapes is mainly summarized in the following three aspects:
The base material of the aluminum foil tape is a soft polymer resin plate, which reduces the plate making cost and shortens the plate making cycle compared with the gravure printing, and the wire mesh version can now reach 175 due to the improvement of the plate manufacturing level and the plate making technology. The level of the line is sufficient for general packaging printing needs.
Zero-pressure printing of aluminum foil tape not only reduces the vibration and wear of the machine, but also reduces the wear of the plate. It also expands the range of printing media, especially for the printing of flexible materials.
The aluminum foil tape uses the anilox roller to transfer ink. Since the anilox roller is both the ink transfer roller and the ink metering roller, it realizes the same short ink path as the gravure printing, and can accurately supply ink according to the process requirements. Currently, laser engraving is adopted. The cermet anilox roll has reached a level of 1600 lines, providing an advantageous means for precise control of ink color and ink layer thickness.
