Thickness of aluminum foil

Thickness of aluminum foil

Aluminium foil roll is a hot stamping material that is directly calendered into thin sheets with metal aluminum. Its hot stamping effect is similar to that of pure silver foil, so it is also called fake silver foil. Aluminum foil is due to its excellent characteristics and aluminum foil roll price. Occupying an advantageous price, it is widely used in food, beverages, cigarettes, photographic plates, household daily necessities, etc., and is usually used as its packaging material.
 
Nowadays, aluminum foil is more and more widely used, and the thickness of aluminum foil is also different for different purposes. If aluminum foil has some typical applications in our daily life and industry, the thickness can determine its performance and application.
 
 
Aluminum foil is usually the most expensive layer in multilayer flexible packaging, so the thinnest possible thickness is used.
The thickness of thick aluminum foil is usually less than 150 μm. The specifications of the thin aluminum foil are as low as 6.0 μm. Thicker aluminum foil specifications (> 17μm) provide an absolute barrier for gases and liquids. At 38°C and 90%RH, the typical water vapor transmission rate (WVTR) of 9μm aluminum foil is 0.3 g/m2 per 24 hours. As the thickness decreases, the foil becomes easier to tear or shrink.
 
 
Aluminum foil products are commonplace in modern times-almost everyone's kitchen can be rolled into a pot for cooking.
Aluminum foil has high thickness and durability, and can withstand a lot of wear. Due to its high puncture resistance and tear resistance, it is the best covering for foil steam table top pots because the pots will bend when carried.
