…how to make airtight containers for your meats or any kind of food.
Or maybe, you’re in the same condition as Aubrey here that shared her story with us.
I have a big hobby of creating my own healthy snacks.
Especially after my son was born, I invested more into creating healthy snacks.
One of his favorites is the wheat chips that I air-fried.
However, it took so long to make even one batch.
So, I tried to make a big batch and put them in our containers.
However, they soon turn very soggy and not crunchy anymore.
I know that we can pop them back in the air-fryer or oven to make them crisp again.
However, isn’t it better if I can make my own airtight container to store my chips?
Yes, It is better! We can relate heavily to Aubrey.

Benefits of airtight container
- Airtight containers are important for keeping food fresh and safe. It is an effective way to preserve food at home and in the kitchen. Food stays fresh longer when it is stored in an airtight container. It is also a good way to prevent food spoilage. Here are the benefits of it:
- It keeps your foods fresher by preventing them from going bad quickly. Airtight containers protect food from moisture loss, contamination, and deterioration. This helps keep food fresh until you consume it. Containers can be lined with plastic wrap (food grade) or aluminum foil, making it easy to control moisture and airflow. These liners will not affect taste.
- They help maintain temperature. The inner walls of the container act as heat insulators. As long as there is no direct contact between the food inside the container and the outside environment, you will still retain the same amount of heat. You can use metal cans like tuna, soup, etc., as a form of insulation. If you want to keep meat cold, place it in a freezer bag or cooler box.
- They help reduce cooking smells. When food is sealed tightly in an airtight container, it has less access to oxygen. Thus, the smell of the food itself doesn’t spread out into the air.
- They prolong shelf life. For example, a bag of sliced tomatoes will last up to 10 days after being packed in an airtight container instead of just 3 days without one.
- Reduce the risk of cross contamination. Since you will avoid using utensils on the food, chances of cross-contamination are reduced.
- Keeps the contents from spoiling. By avoiding exposure to light and high temperatures, the risk of bacterial growth and spoilage is minimized.
