Is aluminium foil a tin foil ?
Is it aluminum foil? The answer is no, but sometimes we hear people mix the two together. Tin foil was once widely used, but now in many applications, aluminum foil has replaced tin foil. The thickness and temperature resistance of the two foils are different. "Tin foil" is produced by rolling metal tin. "Aluminum foil" is produced by metal aluminum rolling. The disposable lunch boxes used on airplanes are now made of aluminum foil and can be placed in a microwave to heat meals. In addition, aluminum foil is also used in hairdressing, packaging, cigarettes, printing, medicine, electronics, food, construction, etc.

In developed countries, packaging aluminum foil products account for 70% of total demand.
Aluminum foil paper has good smoothness and heat reflectivity. With the protection of aluminum foil paper, the taste of cigarettes will not be irritated by external stimulation, and more importantly, it will not be affected by the humidity of the air and the environment. The shredded tobacco will not deteriorate, making them have a longer shelf life! In addition, there are heat insulation and aesthetic factors in it.

In summer, covering a layer of reflective material like aluminum foil on the roof of the building can basically solve 60% of the problem of direct sunlight. The rest is to consider that the metal reflective film itself will become very hot, and the heat will continue to be transferred to the floor.
If this layer of reflective film is raised above the ground and the air circulation layer of 150~200mm is kept between the film and the floor, the effect will be very good.
