Main factors affecting the use and quality of aluminum-plastic composite tapes
Mar 26, 2018

In the production and processing of aluminum-plastic composite tape products, the quality of aluminum-plastic composite tapes will be affected by many related factors. One of the important influencing factors is the cleanliness of the metal tape base surface. In other words, in order to ensure the quality of the aluminum-plastic composite tape, the surface cleanliness of the metal tape base is required to be high. Usually, the surface wettability test (ie, residual rolling oil inspection) should reach Class B or higher.

 

This is because the oil stains and impurities contaminated by the metal tape base surface will affect the peel strength of the aluminum-plastic composite tape product to varying degrees. Under normal circumstances, the aluminum foil passes through the lubricating oil system and the winding process several times during the rolling process, and finally undergoes an annealing process. Of course, the residual rolling oil during the rolling process is mainly removed in the annealing process. But this is not absolute.

 

First, because not all oil stains can be removed in the annealing process. Second, it is not possible to eliminate residual rolling oil on the surface of aluminum-plastic composite tape aluminum foil by any annealing process. Therefore, these factors need to be comprehensively considered to select the lubricating oil that is easy to handle, and at the same time adopt a stricter annealing process to remove as much as possible the oil stain on the surface of the aluminum foil and improve the degree of peeling of the product.

 

At the same time, the quality of the aluminum-plastic composite tape is closely related to the quality of the tape used. In fact, the quality of aluminum foil mainly refers to whether the aluminum foil rolling process is stable and uniform, and whether its strength and elongation are consistent, whether it has “alice” and a phenomenon of “bending knife”, whether there is curling at the time of winding and the aluminum ingot itself. The purity and so on.

 

In addition to these factors, in the production process, the quality of the aluminum-plastic composite tape also has a close relationship with the process temperature conditions. The process temperature refers to the production process temperature of the aluminum-plastic composite tape use product, which mainly refers to the preheating roller (1# and 2#) temperature and the post-processing oven temperature, which is one of the crucial process factors.http://www.copolymercoatedaluminumtape.com/
