Application and difference of aluminum foil tape

Aluminum foil tape can be used for electronic products such as PDA, PDP, LCD monitor, notebook computer, copier, etc. that need electromagnetic shielding. To prevent temperature loss, the steam pipes are wrapped with aluminum tape. Due to the difference in substrates and adhesives, aluminum foil tapes are much stronger than regular scotch tapes. It can be said that if ordinary tape is Zhu Bajie with 36 changes, then aluminum foil tape is Sun Wukong with 72 changes. However, aluminum foil tape is not popular in daily life due to its high cost, high price and special functions. It only shines in some specific areas of industrial products.

One of the biggest features of aluminum foil tape is that it can isolate electromagnetic signals and is widely used in the field of electronic products. For example, transformers, liquid crystal displays of home laptops, and desktop computers are wrapped with aluminum foil tape to shield electromagnetic signals and speed up the transmission of electronic signals. Because it can isolate electromagnetic waves, it also plays a certain role in solving electromagnetic hazards and protecting human health.

The difference between aluminum tape and other tapes can be summarized in the following three aspects:

1. The base material of the aluminum foil tape is a soft polymer resin board. Compared with gravure printing, it not only reduces the cost of plate making, but also shortens the plate making cycle. Due to the improvement of plate manufacturing level and plate-making process, the screen plate can now reach the level of 175 lines, which is enough to meet the needs of general packaging and printing.

2. The aluminum foil tape adopts anilox roller to transfer ink. Since the anilox roller is both a transfer roller for ink and a metering roller for ink, it realizes the same short ink path as gravure printing, and can accurately supply ink according to process requirements. At present, the cermet anilox roller with laser engraving can reach the level of 1600 lines, which provides a favorable means for accurately controlling the ink color and ink layer thickness.

3. The zero-pressure printing of aluminum foil tape not only reduces the mechanical vibration and wear, but also reduces the wear of the board, but also expands the range of printing media, especially for the printing of flexible materials.
