Why a lot of the packaging bag surface is silver foil?
The purpose of packing is to look good, because it is food, so it is also because of hygiene.
Because of the use of aluminum foil can effectively prevent light barrier light, plastic packaging and direct food through accelerated food spoilage.
Because candies are also considering moisture side so many sweets are wrapped in wax paper (because the wax paper can prevent water entering)For example, chocolate is a special kind of candy, its melting point is 36 degrees, it is very easy to get the temperature melting in the hand, so the reason is tin tin foil, the hands of the temperature can be very good to pass out to prevent the chocolate melts quickly.
