Aluminum foil and its composite materials have moisture resistance, gas barrier properties and light blocking properties. More conducive to long-term preservation of chocolate. There are also many aluminum foil composite materials such as coffee, milk powder, and chicken essence.
The aluminum foil paper is not for the purpose of chocolate, but the heat conductivity of the metal is very good. If it is a mold, the plastic is obviously plastic. Then why use aluminum foil?
