Classificatie van aluminiumfolie

Classificatie van aluminiumfolie

Aluminum foil generally refers to a rolled product with a thickness less than 0.2mm and a rectangular cross-section. Echter, the thickness boundaries in different countries are not exactly the same (Table 1-1), and there are more and more aluminum foils below the thickness limit.

Classification method of aluminum foil

There are many ways classification of aluminum foil. They can be classified according to the thickness, vorm, staat, material or application of the aluminum foil.

The classification dimensions we often see are material, thickness and application. During our communication with customers, customers usually have the following requirements:

Real customer inquiry information

Through the above real customer demand information, we understand that customers usually point out the alloy, thickness or use of the required products, which means that these three indicators are very important to customers;

Natuurlijk, there is a certain correlation between these three indicators. Bijvoorbeeld, 10-20 microns width 30cm 8011 aluminum foil is generally a huishoudelijke aluminiumfolie;

Classification of aluminum foil by thickness

Aluminum foil can be divided into thick aluminum foil, single zero foil and double zero foil according to thickness difference.

• ① Thick aluminum foil: Aluminum foil with a thickness of 0.1~0.2mm.
• ② Enkele nulfolie: foil with a thickness of 0.01mm and less than 0.1mm.
• ③ Double-zero foil: The so-called double-zero foil is a foil with two zeros after the decimal point when its thickness is measured in mm. It is usually an aluminum foil with a thickness less than 0. 0075mm.

When expressed in English, thick foil is called “heavy duty aluminum foil”, enkele nulfolie wordt "medium gauge folie" genoemd, en dubbele nulfolie wordt "lichte folie" genoemd.

In het buitenland, aluminum foil with a thickness of ≤40μm is sometimes called light gauge foil, while aluminum foil with a thickness of >40μm is collectively called heavy duty (graadmeter) folie.

Aluminiumfolie kan afhankelijk van zijn vorm worden verdeeld in aluminiumfolie op rol en aluminiumfolie. Aluminum foil deep processing wool is mostly supplied in roll form, and sheet aluminum foil is only used in a few handicraft packaging situations.

Classification of aluminum foil by temper

Aluminiumfolie kan worden verdeeld in harde folie, semi-hard foil and soft foil according to the temper.

• ① Hard foil: Aluminiumfolie die niet zacht is geworden (gegloeid) na het rollen, en heeft restolie op het oppervlak zonder te ontvetten. Daarom, rigid foil must be degreased before printing, lamination, en coating. Als het wordt gebruikt voor vormverwerking, het kan direct worden gebruikt.
• ② Semi-hard foil: Aluminum foil whose hardness (of kracht) is between hard foil and soft foil, usually used for forming processing.
• ③ Soft foil: fully annealed after rolling

The softened aluminum foil has a soft material and no residual oil on the surface. Momenteel, de meeste toepassingsgebieden, zoals verpakkingen, composites, elektrische materialen, enz., use soft foils.

Classification of aluminum foil by surface smooth

Aluminum foil can be divided into one-sided smooth aluminum foil and two-sided smooth aluminum foil according to the surface condition.

• ① Enkelzijdig gladde aluminiumfolie: Dubbelgewalste aluminiumfolie. After being rolled, one side is bright and one side is darkened. Such aluminum foil is called single-sided smooth aluminum foil. The thickness of single-sided aluminum foil usually does not exceed 0.025mm.
• ② Single-sided bright aluminum foil: A single rolled aluminum foil, with both sides in contact with the roller. The two sides of the aluminum foil are divided into mirror double-sided aluminum foil and ordinary double-sided aluminum foil due to the different surface roughness of the roller. The thickness of double-sided aluminum foil is generally not less than 0.01mm.

Classification of aluminum foil by Surface technology

Aluminiumfolie kan worden verdeeld in gewone folie, reliëf folie, samengestelde folie, gecoate folie, colored aluminum foil and printed aluminum foil according to the processing state.

• ① Effen folie: Aluminum foil that has not undergone any other processing after rolling, also called light foil.
• ② Embossed foil: Aluminum foil with various patterns embossed on the surface.
• ③ Composietfolie: Composite aluminum foil formed by laminating aluminum foil with paper, kunststof folie, en karton.
• ④ Gecoate folie: Aluminum foil coated with various resins or paints on the surface.
• ⑤ Color-coated aluminum foil: Aluminum foil coated with a single color on the surface.
• ⑥ Bedrukte aluminiumfolie: Aluminum foil that forms various patterns, patterns, text or pictures on the surface by printing. It can be one color, tot 12 kleuren.

Aluminum foil can be classified by use

Ordinary aluminum foil: usually used in food packaging, preservation, cooking and other fields. This kind of aluminum foil is generally thin, soft and plastic.

Kitchen foil: Specifically designed for cooking and baking, it resists high temperatures and prevents food from sticking to the pan.

Medical Aluminum Foil: Used in the medical industry, for example to shield radiation during X-ray examinations.

Aluminum foil for electronics: It has high electrical and thermal conductivity and is used for packaging and shielding of electronic devices.

Insulating aluminum foil: With an insulating layer, used for the insulation of cables and wires.

Decorative aluminum foil: The surface can be coated, printed or treated and used in areas such as packaging, decoration and advertising.

Air conditioning foil: With special anti-corrosion and thermal conductivity properties, it is used for packaging of air conditioning ducts.

Pharmaceutical packaging foil: used for pharmaceutical packaging and usually needs to meet special standards for pharmaceutical packaging.

Automotive Aluminum Foil: Used in automotive parts such as automotive radiators.

Aluminum foil for construction: used for building insulation, waterproofing materials, enz.
