Like to do food partners, all know aluminum foil and tinfoil, so these two kinds of paper are used in where the best? This article will briefly share the knowledge in this regard:

Aluminum foil paper refers to the paper made of aluminum foil liner and aluminum foil laminating and bonding. Soft and easy to deform, such as paper, and does not rebound after deformation. Can be qualitative, to ensure shading, will not fall, opaque, non-polluting, inexpensive. For advanced cigarettes, candy and other food moisture-proof and decorative packaging. Aluminum foil paper has a wide range of uses, such as: aviation food packaging, general meat packaging, cigarette packaging and so on. According to its application characteristics of different experts, it is divided into more than 20 varieties. Different countries due to the differences in the level of economic development, the structure of aluminum foil consumption is also a big gap.

Aluminum foil paper and tinfoil is first of all the nature of the different, aluminum foil paper is made of metal aluminum or aluminum alloy processed by rolling equipment, the thickness back in the 0.025mm below. Tin paper is processed with metal tin by extension equipment. Then there is a different melting point: aluminum foil paper melting point of 660 ℃. Boiling point of 2327 ℃, the appearance of silver-white light metal, ductile and spreading. In the humid air can form a layer of oxidized film to prevent metal corrosion. Tin paper melting point 231.89 ℃, boiling point 2260 ℃. Has excellent ductility and spreadability.

There are also different uses, aluminum foil paper has a higher melting point than tinfoil, more suitable for grilling food. And tinfoil is mainly used to preserve fruits, such as bananas bought back, we eat the rest of the banana head of the section wrapped in tinfoil, so that you can be very substantial isolation of the air oxygen corrosion of bananas, thus slowing down the speed of its decay, to ensure that it's freshness.

The tinfoil can also be sharpened scissors, take the scissors again and again to cut the tinfoil from the center. After a few consecutive cuts, the scissors will be as sharp as ever. Why is this so? Mainly because the tinfoil in the process of being cut by the scissors play a role similar to a whetstone, so it will make our scissors sharp as ever.
