Aluminum foil for flexible packaging is an essential material in the packaging industry, playing a crucial role in sectors such as industrial, pharmaceutical, and food packaging. Common types include 8079, 8011, and 1235 aluminum foils, typically ranging in thickness from 6 to 25 microns; regardless of your specific requirements, we can provide the precise thickness you need.

The production of ultra-thin 6 micron aluminium foil requires special alloys with certain properties. It is essential for alloys to have a sufficient level of ductility and purity in order to avoid defects such as pinholes, cracks or breaks. The most widely used alloys for the production of the commercial range of 6 micron aluminium foil include 8079 and 1235 alloys, with each of them having specific properties and uses.

Choosing the right aluminum foil food wrap can save you a lot of time and energy and will ensure that your food stays fresh for long.
Aluminum foil food wrap comes with a regular specification known as the 8011-O alloy, with thickness between 8 to 30 microns. The "O" temper signifies that the foil is completely annealed, implying that it is soft and has dead-fold properties, which help make the wraps tight as they will not spring apart.

The purity in the aluminum foil industry affects its performance directly. Pure aluminum foil, made from primary aluminum with fewer amounts of alloying agents, performs better than others in terms of formability, resistance to corrosion, and quality of the surface. Pure aluminum foil is better than the foils made from recycled and alloys of low purity due to the stability of its mechanical properties and cleanliness. It gives more value to the job compared to the foils made from recycled products, for instance, in the manufacturing of food containers, and flexible packaging lamination and pharmaceutical blister packing. It is all due to the fact that pure aluminum foil is easier to form with the help of pressing; it ensures smooth foil formation that is important when conducting lamination and keeps all properties unchanged for longer periods.

For heavy-duty use, foil is 20 microns or thicker. Very thin foils below 6 microns are more susceptible to pinholes and punctures. Texture and surface finish are also signs of quality - high quality foil will have a very smooth, reflective surface without visible flaws, creases or tears. Impurities in poor quality foils can cause a dull or grainy appearance.

Choosing the right thickness of aluminum foil in the 6-15 micron thickness category is a refined balance of performance, functionality, and cost issues. The thickness category represents the industry standard, as it strikes a great balance of performance and functionality. From an end user's view, a 6 or 7 micron foil will have the greatest flexibility (and value) for applications with little stress, such as inner bags of snacks or candy bars. An 8 or 9 micron foil offers a stronger more robust foil that is versatile for applications from butter wraps and yogurt lidstock to portion size condiment pouches.
