Aluminum Foil Inspection and Quality Control Tests:

Wettability Test
The wettability test is performed when you need to determine the dryness of the aluminum foil. During this test various ethyl alcohol / water solutions are poured onto the aluminum foil surface. If no droplets form on the piece of aluminum foil, the wettability will be classified as zero.

Pinhole Determination in Aluminum Foil

The thickness that manufacturers should create aluminum foil should range from about 0.002 inches or more to ensure the aluminum foil is virtually free of pinholes. If aluminum foil ranges less than 0.002 inches then pinholes may appear.

Thickness of Aluminum Foil

Thickness of aluminum foil tests are used to determine the thickness of metallic foils, thin sheets, and films. The test is performed by measuring the mass of the foil. A blanking press will cut aluminum foil into medium sized circles which will be used to determine the mass.

Water Vapor Transmission of Materials
The water vapor transmission of materials test covers the determination of water vapor transmission of materials. These materials would include products such as aluminum foil, paper, plastic film, fiberboard, wood, and plastic.Two of the basic test methods used during inspection are the Desiccant Method and The Water Method.

Aluminum foil and it's popularity will continue to expand in the packaging industry. Medical, military and retail food industries will continue to contribute to the expansion of the packaging industry. Which in return continues to maintain and uphold the quality and durability of aluminum foil worldwide.
