Mylar bags are a type of food storage solution designed to keep your food fresh for an extended period. These bags are made from a material known as BoPET (biaxially-oriented polyethylene terephthalate), which is renowned for its remarkable barrier properties. Innovative custom mylar bags in USA provide an effective shield against light, moisture, oxygen, and pests, making them an ideal choice for preserving the quality and taste of your food.

Mylar bags are available in various sizes and thicknesses, making them versatile for different food storage needs. They are commonly used in long-term food storage, catering, restaurants, and by individuals who want to ensure their food remains edible over an extended period.

The Importance of Food Storage

In a world where food safety and security are paramount, long-term food storage is essential. Whether you’re an average homeowner preparing for emergencies, a restaurant owner aiming to reduce food waste, or a preparer planning for the unexpected, proper food storage is a critical concern. Mylar bags have gained popularity for their effectiveness in this regard, as they offer a robust solution for preserving food.

However, selecting the right Mylar bags, understanding how to use them, and knowing what foods are suitable for storage in these bags are crucial aspects to consider. This article will guide you through the world of Mylar bags for long-term food storage, helping you make informed decisions and better protect your food investments.

Why Choose Mylar Bags

Superior Barrier Properties

One of the primary reasons to choose Mylar bags for long-term food storage is their exceptional barrier properties. Mylar is a highly reflective material that not only blocks light but also provides an impermeable layer against oxygen, moisture, and pests. This airtight seal is essential for preventing food spoilage and maintaining the nutritional value of stored items. In comparison to traditional plastic or glass containers, Mylar bags offer superior protection and extend the shelf life of your food.

Mylar bags are especially effective at shielding against ultraviolet (UV) light. This is crucial because UV light can cause food degradation and nutrient loss. With Mylar bags, you can rest assured that your food remains in a near-original state, even after months or years of storage.


Long-term food storage can be a cost-effective solution when done correctly, and Mylar bags play a significant role in achieving this goal. These bags are relatively affordable, making them an accessible choice for individuals and businesses. Moreover, the extended shelf life they provide reduces food waste, which can save you money in the long run.

Another cost-saving aspect of Mylar bags is their efficient use of space. Since they are lightweight and take up minimal storage space when empty, you can store more food in a smaller area. This efficiency is particularly beneficial for individuals with limited storage capacity or those who wish to stock up on food for emergencies.

Selecting the Right Mylar Bags

Size Matters

Choosing the right size of Mylar bags is a crucial aspect of effective food storage. Mylar bags come in a variety of sizes, ranging from small pouches suitable for individual servings to large bags that can store bulk quantities. When deciding on the size, consider your specific needs and the quantity of food you intend to store.

For long-term food storage, it’s often recommended to use larger bags, especially if you’re planning to store grains, rice, or other staples. This not only ensures that you have enough space for your food but also minimizes the number of bags you need, simplifying the storage process.

Thickness Options

The thickness of Mylar bags, often referred to as the “mil” rating, is another important consideration. Thicker Mylar bags provide increased durability and better protection. For long-term food storage, it’s advisable to choose bags with a thickness of at least 4 mils, as these are more robust and less prone to punctures or tears.

Thicker bags also provide better protection against oxygen and moisture infiltration, which is essential for preserving food quality. While thinner bags may be suitable for short-term storage, investing in thicker Mylar bags ensures that your food remains in optimal condition for extended periods.

When selecting Mylar bags, it’s crucial to strike a balance between size and thickness to meet your specific storage needs while ensuring food safety and longevity.

How to Use Mylar Bags for Food Storage

Steps to Properly Store Food

Storing food in Mylar bags is a straightforward process, but it requires attention to detail to ensure optimal results. Here are the key steps to properly store food in Mylar bags:

  1. Gather Your Supplies: You’ll need Mylar bags, oxygen absorbers, a heat sealer, and the food you want to store. Ensure that the food is clean and dry before packaging.
  2. Prepare the Mylar Bags: Open the Mylar bags and insert an oxygen absorber into each bag. The absorber will help remove oxygen from the bag, preventing spoilage. Ensure the bags are sealed except for a small opening.
  3. Fill the Bags: Carefully fill the bags with the food items, leaving some space at the top to allow for sealing. It’s essential to avoid overfilling, as this can make sealing difficult and less effective.
  4. Seal the Bags: Using a heat sealer, close the bags with a strong, airtight seal. Ensure there are no gaps or openings left. It’s recommended to double-seal the bags for added security.
  5. Label and Date: Don’t forget to label each bag with the type of food stored and the date of packaging. This step helps you keep track of your food inventory and ensures you use the oldest items first.
  6. Store in a Cool, Dark Place: Place the sealed Mylar bags in a cool, dry, and dark storage area. Ideal storage conditions typically range from 50-70°F (10-21°C).

What Foods Can You Store in Mylar Bags?

Non-Perishable Staples

Mylar bags are particularly well-suited for storing non-perishable staples that are commonly found in most households. These include items such as:

  2. Dried Fruits and Vegetables: Whether it’s dried apples, apricots, or vegetables like carrots or peas, Mylar bags protect these foods from moisture and pests, ensuring they stay crisp and flavorful.
  3. Emergency Food Kits: Many companies offer emergency food kits, which contain a variety of dehydrated or freeze-dried foods. These kits are ideal for extended storage and are usually packaged in Mylar bags for longevity.

Mylar bags provide a secure environment for preserving these items, helping you build a well-stocked pantry that’s ready to meet your dietary needs, even in challenging situations.


In the realm of long-term food storage, Mylar bags stand as a trusted guardian of your edible treasures.
