Three states of aluminium coating transfer
Abstract: This article analyzes three states and causes of the aluminium coating transfer, and introduces the corresponding preventive measures.
Aluminium coating transfer frequently happened in the metallized structure during laminating, so how can we effectively prevent the aluminium coating transfer and avoid production waste? In fact, finding out the root of problems is the key. Here’s the cause analysis and preventive measures of aluminium coating transfer.
General speaking, "aluminium coating transfer" is referred to that the aluminium coating is partially or completely separated from the base film when testing the peeling strength.
Three states of aluminium coating transfer
“Completely” transfer: The aluminium coating completely transfers to the glue contact surface.
“Partially” transfer: The aluminium coating does not transfer at the specific ink; but partially transfer between layers.
“Layer” separation: The aluminium coating layer is separated between itself and uniformly distributed in both first substrate and the second substrate (aluminium coating substrate), which is called ”cohesive failure of aluminium coating”.
