advantage:
1. The heat insulation and heat preservation effect of aluminum foil bags is very good. In recent years, as more and more takeaways have been made, it has also made our lives more convenient. Food-grade aluminum foil bags are used to heat food in the winter, allowing us to enjoy the cold winter. You can also get hot takeaway food;
2. Aluminum foil bags have certain good properties of high temperature resistance, low temperature resistance, oil resistance, and flavor retention. They can directly heat food without losing the deliciousness of the food;
3. Nowadays, with the development of science and technology, the aluminum foil bags produced are safe and non-toxic. They are used to package food, medicine, etc., which are non-toxic and tasteless, and meet the hygienic standards for food and medicine packaging;
4. Industrial aluminum foil bags have strong mechanical properties, high blast resistance, puncture resistance and tear resistance;
5. The styles of aluminum foil bags currently sold on the market are rich and diverse, and they are more beautiful after printing, attracting consumers' attention and increasing the value of items;
6. The air barrier performance of aluminum foil bags is also very strong, and it also has good anti-oxidation, waterproof, moisture-proof properties, etc.

Insulation aluminum foil products:
Thermal insulation aluminum foil products will be the fastest growing variety among aluminum foils used in construction: Under the increasingly tight energy situation, more energy-saving building materials are increasingly needed. It is the cheapest and fastest to use thermal insulation materials to achieve energy saving in the construction industry. Methods. From abroad, Japan uses aluminum foil corrugated cardboard, aluminum foil mineral wool board, and aluminum foil polyethylene film frame board for building insulation of factories, residences, and livestock fences; France uses aluminum foil asbestos corrugated board and aluminum foil foam sandwich board for roof insulation and insulation. Sound-absorbing materials; Russia uses aluminum foil composite insulation materials for wall, roof and floor insulation. Domestic building insulation and energy conservation are also showing a new development trend. Aluminum foil insulation roofs have been widely used in Henan, Jiangsu, Sichuan, Guizhou, Zhejiang, Hubei, and Jiangxi, and this trend will further expand.

Air conditioning foil:
(1) The thickness of air conditioning foil is thinner; as the forming method of air conditioner heat dissipation fins changes from traditional stretch molding to thinning stretch molding (high-speed thin-walling), the thickness of aluminum foil tends to be thinner, and will be from the current 0.095 mm thinned to 0.09mm-0.08mm.
(2) The application proportion of hydrophilic aluminum foil will increase; hydrophilic foil is coated with anti-corrosion inorganic coating and hydrophilic organic coating on the surface of aluminum foil. It also has the functions of anti-corrosion, anti-mold, and no odor. Mainly Used in radiators (mainly used in air conditioners, but also in some capacitors, etc.). Good formability and no wear on the mold; extremely strong stamping resistance, solvent resistance, and heat resistance: the air flow is small, the heat exchange rate can generally be increased by 10%-15% compared to light foil, and the heat sink can reduce wind resistance , reduce noise, reduce energy consumption and extend service life. Therefore, the proportion of hydrophilic aluminum foil in the total volume of air-conditioning aluminum foil will increase, and is expected to reach a maximum of 80% by 2010.
(3) The varieties of hydrophilic aluminum foil will be further refined: In order to meet the segmentation requirements of the household air conditioner market, highly corrosion-resistant hydrophilic aluminum foil, antibacterial hydrophilic aluminum foil, super hydrophilic aluminum foil, and nano-organic hydrophilic aluminum foil will be industrialized change.
(4) The mandatory improvement of air-conditioning refrigeration efficiency has promoted the increase in the consumption of aluminum foil for single-unit air conditioners.

Aluminum foil is very common in our daily life. As we all know, it is a metal flat tool used for kitchen cooking, food sealing and some easy-to-clean materials. Thousands of tons of aluminum foil are used every year to package food, cosmetics and chemicals. .
Aluminum foil is very flexible and can be formed into different shapes. Aluminum foil can be used to warp both sides of the foil. Most of the foil is bright and one side is black. It can be used to warp bread and increase heat conduction. In addition, aluminum foil can also be used for decoration and as an insulating conductor for heat exchange and electrical conductors. The thickness of aluminum foil used as food packaging paper is only 6.5μm. Thin aluminum foil stays in good condition and resists water, bacteria and dirt.
