Quick Answer
Mylar bags are a preferred choice over mason jars for food storage due to their superior ability to prevent oxygen, moisture, and light from reaching the stored contents, thereby extending shelf life.
Choosing the Right Mylar Bag
When selecting a Mylar bag for food storage, consider the following factors: material thickness (at least 5 mil), width (at least 6 inches for easy resealing), and length (dependent on the type and quantity of food being stored). A good starting point is a 6-inch wide by 8-foot long bag.
Key Benefits of Mylar Bags
Mylar bags offer several key benefits over mason jars, including better moisture protection, improved gas barrier properties, and increased durability. They also allow for easy resealing and are more versatile in terms of size and shape. When paired with oxygen absorbers, Mylar bags can effectively remove oxygen and create an inhospitable environment for pests and mold, extending the shelf life of stored food.
Preparing and Sealing Mylar Bags
To use Mylar bags effectively, first prepare the contents by removing any air pockets and adding oxygen absorbers (approximately 1-2 ounces per 1 gallon of storage space). Next, remove as much air as possible from the bag using a vacuum sealer or the displacement method. Finally, seal the bag using a heat sealer or iron, ensuring a tight seal to prevent moisture and air from entering. By following these steps, you can create an airtight environment that preserves food for months or even years.
