Food grade aluminum foil for packaging
The previous aluminum foil cannot be rolled very thin, and the cost is relatively high, so it is replaced by tin foil. However, with the continuous advancement of technology, the problem of inability to thin has been solved. Nowadays, the packaging of chocolate or other snacks is already in the world of aluminum foil. Compared with tin foil, it is safer and more hygienic. As metal tin, tin foil contains lead. We all know that lead has a hindering effect on the absorption of calcium in the human body and is harmful to human health. The aluminum foil has no such damage, so it is safer and more hygienic. As a relatively rich resource among metal resources, aluminum has now been widely used in various fields.
