What are the strengths of 8011 aluminum foil? The 8011 aluminum foil is one of the most common alloys for packaging.

You will find it in every household kitchen, takeaway containers, as well as lidding film and general flexible packaging.

What makes 8011 such a popular material is an ideal compromise between strength, formability, corrosion resistance, and price.

The thinner the foil is the more fragile it becomes. For example, foils below 9 microns tend to be fragile, easily tearable, and wrinkled.

When working with such thin foils, the manufacturers can face problems of production downtime.

On the other hand, thick foils are better in terms of their dimensional stability. Such foils have gauges above 12 microns which allows them to keep flat and be uniform in tension.

The alloy produces a different combination of properties, including tensile strength, elongation, formability, corrosion performance and barrier efficiency, and impacts the behavior of the master roll through the entire production process from rolling to slitting, lamination and converting.

Heat sealing Packaging relies on a proper interaction between aluminum foil and a sealant layer. Incorrect foil characteristics cause failure of the seal resulting in product contamination and spoilage. Heat sealing, unlike traditional lamination, applies heat, pressure, and dwell to a packaging structure.

Henan Tendeli Metallurgical Materials Co., Ltd., developed in 2009, is able to produce 8011, 8079, 1235, 3003, 8006 aluminum foil master rolls with documented quality standards, food-grade certification and consistent batch assurance. HTMM has more than a decade of export experience, serving over 3,000 customers worldwide. Standards are there to protect both buyer and supplier.

While buyers pay attention to thickness, pinhole rate and barrier performance, they tend to overlook the concept of tensile strength, which is one of the important mechanical characteristics of aluminum foil and impacts the production efficiency, yield rate and quality of finished products.
