With the improvement of people's living standards and the development of tourism, the demand for beverages and canned foods such as beer and soda is increasing, which requires modern packaging and decoration to facilitate competition in the international market. In order to meet the market requirements, people have developed packaging materials such as plastic films and sprayed foils with good shielding properties, but their comprehensive properties are not as good as overcoating and lamination can be compensated and improved. Therefore, it can be said that aluminum foil is a perfect packaging material with a variety of excellent properties, and it has fully shown its broad application prospects in many fields.

At present, aluminum foil has been fully integrated into our lives.

Household foils are widely used in cooking, freezing, preservation, baking and other industries. In the refrigerator or freezer, the aluminum foil can be directly wrapped on the food, which can keep the food from being deformed, and can avoid the water loss of fish, vegetables, fruits, and dishes, and prevent the leakage or mixing of flavors. Since aluminum foil has good and uniform thermal conductivity and heating effect, it can be used in ovens, steamers, etc. to heat directly on the original packaging. Common specifications: 0.007-0.05mm.

The medicinal foil has the advantages of non-toxicity, corrosion resistance, impermeability, heat resistance, moisture resistance, light resistance and high temperature sterilization. , In particular, PTP aluminum foil is moisture-proof, easy to carry, safe and hygienic, and is widely used in the international pharmaceutical industry. The production environment requirements of medicinal aluminum foil processing plants are relatively high, such as requiring no less than 100,000-level purification workshops. Commonly used medicinal foils on the market are available in two alloy states. State: O, after cold stamping, used for high-grade pharmaceutical packaging; State: H18, after coating, used for ptp medicinal aluminum foil, commonly used thickness: 0.006-0.08mm.

Battery foil is one of the base materials of lithium batteries for new energy vehicles. Usually, the lithium ion battery industry uses rolled aluminum foil as the positive electrode current collector. Common specifications: 0.009-0.1mm.

Air conditioner foil is a special material for the manufacture of heat exchanger fins for air conditioners. The air conditioner foil used in the early days was plain foil. In order to improve the surface properties of plain foil, it is coated with an anti-corrosion inorganic coating and a hydrophilic organic coating before forming to form a hydrophilic foil, which is widely used in household industrial air conditioners, refrigerators, automotive air conditioners and other refrigeration equipment. In addition, there is a hydrophobic foil, which makes the surface of the fins have a hydrophobic function to prevent condensed water from sticking to it. It is mainly used in dryers to improve heating efficiency. The thickness of the air conditioner foil is 0.07mm~0.2mm. With the development of technology, there is a trend of further thinning of air-conditioning foil.

Honeycomb aluminum foil has the advantages of light weight, high strength and high rigidity, and is widely used in the exterior wall decoration of high-rise buildings. Commonly used thickness is 0.035-0.08mm.

After the electronic aluminum foil is processed into foil, it is subjected to surface corrosion treatment and reoxidation treatment, and then wound processing to make capacitors. The aluminum foil before corrosion is called light foil, the aluminum foil after corrosion is called corrosion foil, and the aluminum foil after reoxidation is called finished foil. Electronic aluminum foil refers to the light foil, which is the key raw material for the production of aluminum electrolytic capacitors. The electrode foil includes corrosion foil and chemical foil. Electronic aluminum foil can be divided into high voltage anode foil, low voltage anode foil, negative electrode foil, etc. Among them, high and low voltage anode foils (formed foils) need to use more than 99.99% high-purity aluminum. The thickness of high-voltage anode foil is 0.0065-0.11mm, and the thickness of low-voltage anode foil is 0.04-0.1mm

Flexible packaging is a bag-type container made of flexible composite packaging materials. Different processes such as dry lamination, hot melt lamination, and extrusion lamination are used according to the different uses of flexible packaging. Flexible packaging not only has the functions of moisture-proof and fresh-keeping, but also can print various patterns and characters. It is an ideal material for modern commercial packaging. Common specifications: 0.0058-0.03mm.

It is used in fast food restaurants, takeaway speed matching stores, high-end hotels, aviation tableware, home kitchens and other food utensils. It has the characteristics of beautiful appearance, convenient use, safety and hygiene, and no odor pollution. Common specifications: 0.01-0.2mm.

The aluminum foil for cigarettes is mainly used as the inner lining paper of the cigarette box after being compounded with paper. The surface of the cigarette foil is smooth and traceless, the plate shape is flat, the pinholes are few, the cost is relatively low, and the chemical properties are relatively stable. The aluminum foil paper in the cigarette case has two main functions: one is to preserve the fragrance, the aluminum foil paper can prevent the smell of cigarettes from emitting, and at the same time prevent the smell of cigarettes from eroding other items; the other is to prevent mildew. Aluminum foil can block moisture and effectively prevent moisture, so as to avoid mildew on cigarettes in humid environments. The thickness is basically 0.0063-0.0065mm.

The cable foil is an aluminum #plastic composite foil formed by using the airtightness and shielding properties of the aluminum foil to coat the plastic film on one or both sides, which is used as a shield for the cable. The cable foil requires less oil on the surface, no holes, and high mechanical properties. The overall quality requirements are not high, but the length requirements are extremely strict. Common thickness is: 0.007-0.2mm.

Decorative foil is a decorative material applied in the form of aluminum-plastic composite, which utilizes the characteristics of good colorability and high light and heat reflectivity of aluminum foil. Mainly used for construction, furniture decoration and part of gift box packaging. It is generally used as a decorative material for the inner wall of buildings and indoor furniture, and is also widely used in the facade and interior decoration of commercial institutions. Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire resistance and easy cleaning. Thickness is usually in: 0.01-0.2mm.
