Food grade aluminum sheet refers to aluminum materials that are free of heavy metals, toxic and hazardous substances during production and processing, meet domestic and international food safety standards, and are non-toxic, tasteless, odorless and non-polluting. This type of aluminum sheet is usually manufactured from 3000 series aluminum alloys, such as 3003, 3004, an alloy that contains manganese and other trace elements, giving it excellent formability and corrosion resistance. In addition, other series such as 1100, 1060, 5052 and 6061 are also used to produce food grade aluminum sheet, which also offer good processing characteristics and safety.

Commonly used food grade aluminum sheet grades are:

• 3004 aluminum sheet: good at forming processing, mostly used in moldable beverage cans, cosmetic packaging, candy cans and so on.
• 3104 aluminum sheet: also good at forming processing, commonly used in food packaging, can lids, paint drums, etc.
• 3003 aluminum sheet: widely used in food, beverage, medicine, cosmetic packaging and other fields.
• 5052 aluminum sheet: because of the flat surface, no corrosion, no oxidation skin, mostly used in reusable food, medicine, cosmetics packaging boxes, etc..

Performance advantages of food grade aluminum sheet are:

– Excellent corrosion resistance

The surface of food-grade aluminum sheet naturally forms a layer of oxide film, which effectively prevents the erosion of oxygen and water on the internal metal, so that even if the aluminum sheet is exposed to a long period of time in a humid environment, it can remain intact.

– Excellent molding ability

Thanks to a specific alloy composition, food-grade aluminium sheet has excellent forming properties. This means that it can easily be cut, bent or stamped into a variety of shapes, making it ideal for making complex containers and packaging materials.

– Good weldability and workability

This type of aluminum sheet is not only easy to weld, but it also performs well in subsequent processing, either through machining or heat treatment to achieve the desired results.

– Environmentally friendly and healthy

Food-grade aluminum sheets do not contain heavy metal elements that are harmful to the human body and can be recycled, reflecting the concept of green environmental protection and contributing to the construction of a sustainable society.

Thanks to these advantages, food grade aluminium sheet is widely used in many fields. For example, in the food industry, it is often used to manufacture cans, bottle caps and various forms of packaging foil; in the food service industry, it is the ideal choice for disposable tableware such as fast food boxes and trays; at the same time, in the household kitchen, you can also see a variety of kitchenware and utensils made of food-grade aluminum, which provides convenience and safety for people’s daily life.
