Aluminium Foil

Aluminium foil also called the tin foil is aluminium prepared in thin metal leaves. The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. The most important (mechanical) properties for films and tapes are the tensile strength, the yield strength and the elongation. These properties are important both for single-layer foils (ie, for example, pure aluminum foils) and for laminates.

In the case of laminates, adhesion is also important. The bonded adhesion is used to indicate how well the individual layers adhere to each other. Depending on the application, characteristics such as degree of gloss, water permeability and vapor permeability, or the degree of emissivity also play a role.
