When it comes to food storage, ensuring your supplies remain fresh and safe over time is paramount. Enter Mylar bags, a popular solution for long-term food storage that has gained significant traction among preppers, survivalists, and anyone looking to extend the shelf life of their pantry staples. But what makes mylar bags for food storage so special, and how can you best utilize them for your food storage needs? Let’s dive in.

Definition and Composition

Mylar bags are made from a type of polyester film known as BoPET (biaxially-oriented polyethylene terephthalate). This material is renowned for its excellent barrier properties, which include resistance to moisture, light, and oxygen – the three main culprits that lead to food spoilage.

History and Development

Originally developed in the 1950s, Mylar was first used in various industrial applications. It wasn’t long before its potential for food storage was recognized, leading to its widespread adoption in households and food storage systems.

Extended Shelf Life

One of the primary benefits of Mylar bags is their ability to significantly extend the shelf life of food products. By protecting against oxygen, moisture, and light, Mylar bags help keep food fresh for years, sometimes even decades.

Protection Against Elements

Whether you’re storing grains, dried fruits, or freeze-dried meals, Mylar bags offer robust protection against environmental factors that can degrade food quality. They are especially useful in areas prone to humidity or temperature fluctuations.

Versatility

Mylar bags come in various sizes and thicknesses, making them suitable for storing a wide range of food items. From small portions of spices to large quantities of rice or beans, there’s a Mylar bag for every need.

Different Thicknesses

Mylar bags come in different thicknesses, typically ranging from 3.5 mils to 7 mils. Thicker bags offer better protection but can be more challenging to seal properly.

Sizes and Capacities

These bags are available in multiple sizes, from small pint-sized bags to large five-gallon bags, allowing for flexible storage options based on your needs.

Variants with Zippers and Valves

Some Mylar bags come with added features like zippers for resealing or one-way valves for packaging products like coffee that off-gas.

Oxygen Absorption

Mylar bags work in conjunction with oxygen absorbers to create an oxygen-free environment, which is crucial for preventing the growth of aerobic bacteria and mold.

Light and Moisture Barriers

The metallic film of Mylar bags acts as a barrier to light and moisture, further preserving the contents and preventing degradation.

Factors to Consider

When selecting Mylar bags, consider factors such as thickness, size, and any additional features like resealable zippers or valves. The type of food you plan to store will also influence your choice.

Recommended Brands

Brands like Sorbent Systems, ShieldPro, and Foodsaver are highly recommended for their quality and durability.

Dry Goods

Items like rice, pasta, and flour store exceptionally well in Mylar bags. Ensure they are dry and use the correct size oxygen absorber.

Freeze-Dried Foods

Freeze-dried foods can last for decades when stored in Mylar bags with oxygen absorbers, making them ideal for long-term emergency storage.

Grains and Legumes

Grains and legumes are also great candidates for Mylar storage. Be sure to check for any insects before sealing, as they can survive in a low-oxygen environment.

Ideal Conditions

Store Mylar bags in a cool, dark place to maximize their effectiveness. Avoid areas with high humidity or temperature fluctuations.

Storage Locations

Basements, pantries, and dedicated food storage rooms are ideal locations. Ensure the bags are not exposed to direct sunlight or sharp objects.

Overfilling Bags

Avoid overfilling Mylar bags to ensure a proper seal. Leave enough space to seal the top without spilling the contents.

Not Using Oxygen Absorbers Correctly

Using too few oxygen absorbers or not sealing the bag immediately after adding them can compromise the storage environment.

Eco-Friendly Practices

To minimize environmental impact, use Mylar bags responsibly. Reuse them when possible and recycle them properly.

Disposal Methods

Check with local recycling programs to see if they accept Mylar bags. Alternatively, find creative ways to repurpose them.

Mylar bags are an invaluable tool for anyone looking to store food long-term. They offer superior protection against the elements and can significantly extend the shelf life of your food. Whether you’re prepping for an emergency or simply looking to keep your pantry items fresh, Mylar bags are a versatile and reliable solution.
