Household aluminum foil roll is one of the essential tools for cooking, ovens and other equipment. However, the correct way to use aluminum foil has confused many people. Which side of the aluminum foil is correct?
Foil Roll Introduction
Aluminum Foil, also known as tin foil, is a cooking material with high temperature resistance, heat resistance and wear resistance. It can not only prevent food from sticking to the container, but also protect the oven from oil stains. At the same time, aluminum foil can also Prevents food grease and juice from spilling, making baking easier and more convenient.
In addition to baking and barbecue, aluminum foil is used in daily grilling and cooking. Life is also filled with many aluminum foil products. For example, potato chip packaging, pudding lids, etc.
It was originally made of tin, but because the texture of tinfoil is softer than that of aluminum foil, and it has the disadvantage of retaining the smell of tin in food, when the price of aluminum fell later, it replaced tinfoil, and the modern “aluminum foil” was born.
Aluminum Foil Roll Glossy and Matte Sides: How to Use
- The glossy and matte surfaces of aluminum foil are only different in appearance.
The difference between the bright side and the matte side of aluminum foil paper is only in appearance. In the final process of aluminum foil production, the two layers of foil pass through the rolling mill at the same time, and the side that is highly polished and in contact with the machine is the bright side.
- There is no significant difference in heating and heat conduction
Should aluminum foil be glossy or matte? There is no significant relationship between the shiny or matte side of the aluminum foil facing outward and the level of heat transfer. Therefore, the front and back sides of the aluminum foil paper face outward and have the same thermal conductivity and insulation effects.
Is Aluminum Foil Toxic?
Aluminum is a heavy metal, and excessive intake may affect the nervous system. The Food and Drug Administration of the Ministry of Health and Welfare reminds that acidic foods or sauces will corrode aluminum foil and dissolve aluminum ions. It is recommended to cook the ingredients first, remove the aluminum foil, and then add Vinegar, lemon, tomato paste and other acidic substances. In addition, if the surface of the aluminum foil is scratched, it is recommended to replace it with a new one.
Can Aluminium Foil be Microwaved?
Never microwave aluminum foil. Aluminum foil is metal and will reflect microwaves, cause sparks, damage the microwave, and reduce the heating effect of food. Even though the oven seems to be safe, don’t be careless. When using it, you need to pay attention to the distance between the aluminum foil paper and the heating lamp. Usually in order to prevent food from overheating or burning, some people use small pieces of aluminum foil to “shield” food areas, such as chicken legs or wings, when using microwave cooking.
The US FDA (Food and Drug Administration) states that it is safe to use small amounts of aluminum foil in microwave ovens under certain conditions.
Microwave Safe Aluminum Foil:

- Hold the foil smoothly against the food so the edges don’t stick out.
- Aluminum foil covers no more than 1/4 of the food.
- Keep the aluminum foil at least 2.5cm away from the oven wall.
When Foil Roll is Not Allowed to be Microwaved:
- There is a metal rack or metal turntable inside the microwave oven
- The instructions indicate that aluminum foil should not be used
- See sparks when microwaving
