Aluminium foil (Aluminium foil), also known as aluminium foil, is called tin foil in Hong Kong. It is a tool made of flattened metal aluminium. It is mainly used for cooking in the kitchen, to hold food, or to make something that can be easily made. Clean materials. Hundreds of thousands of tons of aluminium foil are used worldwide to protect and package food, cosmetics and chemicals. Most aluminium foil is shiny on one side and dull on the other. The aluminium foil paper used for food can be wrapped on both sides of the food. Generally, it is recommended to wrap it with a bright surface to improve the heat transfer effect.

History: The original tin foil was really made of tin. Tin foil was harder than aluminium foil, and it also brought a tin smell to food. Therefore, after the aluminium price dropped, aluminium foil replaced tin foil in daily life. However, because metal aluminium can affect the development of the brain, the surface of the current aluminium foil is coated with a coating to avoid the release of metal aluminium.

Aluminium is used in food containers for different reasons: it provides a very good barrier to protect food against light and air and preserves food quality; it can be recycled and designed individually according to customers’ requirements; it can be produced in different sizes and shapes. In addition, aluminium is a lightweight material and for this reason it has a positive effect on the production costs.

Is an aluminium foil container good for use?

Aluminium packaging has many advantages over other forms of packaging. For this reason, aluminium food containers are used in a wide range of applications. Here some advantages of aluminium foil trays:

• Heat conductivity (aluminium distributes heat homogeneously improving the cooking of food in the oven)
• Hygiene and safety (aluminium is sterile and safe for use in direct contact with foodstuffs)
• Multi-mode cooking (aluminium containers can be used in traditional oven and with some precautions in microwave too)
• Sustainability (aluminium foil trays are fully recyclable)
• Performance (aluminium food containers can be used in the domestic and industrial sectors)
• Design (round or square, big or small size, these containers can be made to fulfil any number of functions)

Functions:

• Aluminium paper is usually used to carry food (such as: aluminium foil paper trays).
• When roasting, it is used to wrap bean sprouts, potatoes, sweet potatoes, etc. to prevent them from burning.

• There are also hairdressers who perm the guests with aluminium foil.
• Some people also use aluminium foil to absorb the oil in the soup.

Uses:



Holding Food: It is very common to use aluminium foil paper trays to hold food. Although aluminium foil paper trays are disposable, the composition is aluminium, which is less harmful to nature.

Barbecue: Some foods (such as sweet potatoes, mushrooms, etc.) must be wrapped in aluminium foil to avoid burning. It is wrapped in aluminium foil to cook seafood, oyster mushrooms, etc., which can retain the umami flavor.

Hair Styling: Some hair stylist will wrap the hair with aluminium foil to heat the hair and have better heat transfer effect. Improper hair using aluminium foil can cause burns and poor hair quality.

Oil absorption: After opening the aluminium foil paper in a ball, you can absorb the oil in the soup. The principle is that during the crumpling of aluminium foil paper, the surface tension of the aluminium foil paper will be amplified.
