Double Zero Aluminum Foil

Double zero aluminum foil usually refers to aluminum foil with a thickness of 0.01 mm (10 microns) or less. Its name comes from the way its thickness unit is expressed, usually with “00” to indicate that its thickness is below 0.01mm. Usually the thickness is 0.0063mm~0.0075mm. Double-zero aluminium foil is a high-grade product among aluminum foils, which is named for its extremely thin thickness and is widely used in the fields of packaging, heat insulation, electronics, and so on.

The main alloy compositions of double zero aluminum foil include aluminum alloys of Series 1000, Series 3000, Series 8000, and so on. Common grades include 1235, 8011, 8079, and so on. The selection of these aluminum alloy compositions is mainly based on their good ductility, corrosion resistance, strength and other characteristics to meet the performance requirements of double zero foil in different fields.

– 1235 alloy: pure aluminum with good ductility and conductivity, suitable for food packaging.

– 8011 alloy: commonly used in packaging and preservation, with good strength and corrosion resistance.

– Alloy 8079: similar to 8021, commonly used in flexible packaging.

Double-zero aluminum foils are typically 0.006mm to 0.01mm thick, depending on the application. Thicknesses of double-zero foils typically range from 0.0063mm to 0.0075mm, with some manufacturers able to produce thinner or thicker double-zero foils. Aluminum foils with a thickness of 0.0055mm or less are called ultra-thin foils and are a higher grade of aluminum foil.

Characteristics of double zero aluminum foil are:

– Extremely thin and lightweight: double zero foil has an extremely thin thickness, making it lightweight and easy to transport and use. Excellent barrier properties: effective barrier properties.

– Excellent barrier properties: effectively blocks moisture, oxygen and light, extending the shelf life of the product.

– Good ductility: easy to mold and process, suitable for a variety of packaging shapes.

– High temperature resistance: remain stable in high temperature environment, not easy to deform.

– Recyclability: environmentally friendly material with reuse value.

Double-zero foil is widely used:

– Food packaging: such as snacks, cooked food, frozen food packaging.

– Pharmaceutical packaging: used for moisture-proof and oxygen-insulating packaging of pharmaceuticals.

– Cosmetic packaging: to protect the stability of cosmetics.

– Electronic products: as insulating materials and electromagnetic shielding materials, such as capacitors, batteries, semiconductor devices.

– Art Decoration: The metallic luster and softness of double-zero foil make it widely used in the field of art decoration, such as paintings, decorations, handicrafts and so on.

The production process of double zero aluminum foil mainly includes the following steps:

– Melting and casting: the raw aluminum alloy is melted in the melting furnace and then cast into aluminum billet.

– Rolling: The aluminum billet is rolled through several passes, gradually reducing the thickness until the required thickness of double-zero foil is reached.

– Cutting and Packaging: The rolled double-zero foil is cut to the required size and packaged for storage and transportation.

– During the production process, parameters such as temperature, atmosphere and rolling pressure need to be strictly controlled to ensure the quality and performance of the double-zero foil. At the same time, the waste in the production process needs to be properly disposed of to minimize the pollution of the environment.

In summary, double zero aluminum foil is a kind of aluminum foil product with extremely thin thickness, high conductivity, high barrier property and easy processing, which is widely used in food packaging, electronic field and art decoration. Its production process requires strict control of various parameters to ensure the quality and performance of the product. Double-zero foil has become one of the indispensable materials in the modern packaging industry due to its excellent performance and wide range of applications.
