What are Mylar bags?
Mylar bags are storage bags made from a type of polyester film known as biaxially oriented polyethylene terephthalate (BoPET). This film is known for its excellent oxygen and moisture barrier properties, making Mylar bags an ideal choice for long-term food storage. They are commonly used in the storage of dried foods, snacks, and bulk grains since they can protect against light, air, and humidity.
Additionally, Mylar bags are often used in combination with oxygen absorbers to maximize their effectiveness for long-term storage. This combination not only helps to keep food fresh but also extends its shelf life significantly. They are available in various sizes and often come with a resealable feature for convenience.
What are vacuum bags?
Vacuum bags are specially designed bags that remove air from the packaging in order to create a vacuum seal around the food. This vacuum sealing process reduces the amount of oxygen in contact with the food, which helps inhibit the growth of bacteria and mold, ultimately extending the shelf life. Vacuum bags are commonly used with vacuum sealing machines, which create the airtight seal.
These bags are flexible, durable, and designed to withstand temperatures that allow for sous vide cooking or freezer storage. They are suitable for a wide variety of food types, including meats, vegetables, and prepared meals, making them a versatile option for food storage.
Which option is better for long-term storage?
When it comes to long-term storage, both Mylar bags and vacuum bags have their advantages. Mylar bags provide an excellent barrier against moisture, light, and air, especially when used in conjunction with oxygen absorbers.
