We have collected the most frequently asked questions that wholesalers may ask. You can check these questions answers for reference if you have any concerns to wholesale aluminium foil containers.
1. What is the raw material of aluminum foil containers?
The raw material of aluminum foil containers is food grade aluminium, the most popular aluminium grade is 3003, 3004, 8006 and 8011 aluminum.
2. What is the aluminum foil container thickness?
The thickness of aluminum foil container is generally between 0.03mm and 0.20mm. You can also customize the foil container with tailored thickness.
3. What is the aluminum foil container usage precautions?
- Do not use corrosive substances or sharp knives to scratch the surface of the aluminum foil container.
- For cooking in high temperature environments, it is recommended to use thicker aluminum foil containers to avoid easy cracking.
- If you want to heat food for a long time, it is best to cover the top of the aluminum foil container with a layer of tin foil to protect the food from excessive burning.
- If there is liquid food in the aluminum foil container, it is recommended to re-wrap it with tin foil before refrigeration to prevent food from leaking or contaminating other foods.
- If the food in the aluminum foil container has been sealed, the sealing film or lid should be removed before putting it in the refrigerator to avoid changes in air pressure that may cause the aluminum foil container to deform.
4. Why aluminum foil container has poor sealing effect?
One of the common problems with aluminum foil container is poor sealing, which makes the food easily susceptible to external influences and spoilage.
This problem is usually caused by insufficient fit between the aluminum foil container and the lid or deformation of the aluminum foil container.
5. Why aluminum foil container is easy to deform?
Aluminum foil containers are often used to heat food, but after high temperature heating, aluminum foil containers are easy to deform, resulting in poor airtightness.
The reason for this is that the thickness of the aluminum foil used is not enough or its structure is not enough to withstand high temperature heating.
6. Why Aluminum foil containers are prone to breaking?
When using aluminum foil containers, it is often found that it is very easy to break, causing food to spill and lose some important nutrients.
The reason for this is that the wall thickness of the aluminum foil containers is not enough and the tear strength is not enough.
7. Is there any harm in using aluminum foil containers for direct heating?
You can rest assured that the raw material of aluminum foil containers is food grade aluminum foil.
Aluminum foil containers are increasingly used in the packaging of grilled fish, grilled meat, steamed food, airline food, etc.
Aluminum foil containers are all coated and will not react chemically in the air, so they will not produce toxic substances.
8. Why does the aluminum foil containers become soft?
When using aluminum foil containers, if the temperature of the food is too high or there is too much fat, the aluminum foil inside the container will become soft and deformed.
In addition, it may also be caused during transportation, storage or use.
9. How to prevent aluminum foil containers from becoming soft?
1). Appropriately lower the temperature of the food.
Before storing hot food in an aluminum foil container, you can wait for a while to cool down, or add an appropriate amount of cold drinks or ice cubes to quickly cool down to prevent the aluminum foil from becoming soft due to excessive temperature.
2). Reasonably control the amount of edible oil.
The catalyst additives in the aluminum foil container will react with the edible oil, causing the aluminum foil to soften and deform, so it is very important to properly control the amount of edible oil used.
3).Do not overlap when storing.
When using aluminum foil containeres, it is best not to overlap them to avoid squeezing and deforming the food contained in them.
4).Avoid pressure when storing.
When storing aluminum foil containeres, it is best to store them separately from other items to avoid external squeezing or collision.
5).Do not twist excessively during use.
When using the aluminum foil container, try to avoid excessive twisting or folding to avoid excessive deformation.
