Storing Food Mylar Bags

Introduction to Mylar Bags

Mylar bags have gained popularity as a preferred choice for food storage due to their exceptional properties and versatility. In this section, we will explore what Mylar bags are and why they have become a popular option for preserving food.

What are Mylar Bags?

Mylar bags, also known as BoPET (biaxially-oriented polyethylene terephthalate) bags, are made from a durable polyester film known for its excellent barrier properties. These bags are typically metallized with aluminum to enhance their barrier capabilities, making them impermeable to moisture, oxygen, light, and odors. Mylar bags are available in various sizes and thicknesses to accommodate different storage needs and can be sealed using heat or ziplock closures to ensure an airtight environment.

Why are Mylar Bags Popular for Food Storage?

  1. Preservation of Freshness: Mylar bags create a protective barrier that seals in freshness and flavor, preventing exposure to air, moisture, and other contaminants that can cause food spoilage. This makes them ideal for storing perishable items such as grains, nuts, dried fruits, and dehydrated foods.

  2. Extended Shelf Life: The barrier properties of Mylar bags help prolong the shelf life of packaged foods by preventing oxidation and degradation. By minimizing exposure to external factors that can accelerate deterioration, Mylar bags help maintain the quality and nutritional value of stored foods for longer periods.

  3. Versatility and Convenience: Mylar bags are versatile and can be used for various types of food storage, including long-term storage, emergency preparedness, camping, hiking, and travel. Their lightweight and flexible design make them easy to store, transport, and handle, providing convenient solutions for different storage needs.

Benefits of Storing Food in Mylar Bags

Storing food in Mylar bags offers a multitude of benefits that contribute to effective preservation and long-term storage. In this section, we will delve into the advantages of using Mylar bags for food storage.

Long-Term Preservation

  1. Extended Shelf Life: Mylar bags create a barrier against moisture, oxygen, and light, which are primary factors contributing to food spoilage. By sealing food items in Mylar bags, their shelf life can be significantly extended, allowing for prolonged storage without compromising quality or freshness.

  2. Preservation of Nutritional Value: The protective environment provided by Mylar bags helps preserve the nutritional content of stored foods by minimizing exposure to external elements that can degrade vitamins, minerals, and other essential nutrients over time.

Protection Against Moisture, Oxygen, and Light

  1. Moisture Barrier: Mylar bags are impermeable to moisture, preventing the absorption of water vapor that can lead to mold growth, spoilage, and deterioration of food quality. This barrier ensures that stored foods remain dry and free from moisture-related issues.

  2. Oxygen Barrier: Oxygen can accelerate the oxidation of fats and oils in food, leading to rancidity and loss of flavor and nutritional value. Mylar bags provide an effective barrier against oxygen ingress, preserving the freshness and integrity of packaged items.

  3. Light Barrier: Exposure to light can cause degradation of vitamins, proteins, and pigments in food, resulting in loss of nutritional value and changes in color and flavor. Mylar bags block out light, protecting stored foods from UV radiation and light-induced degradation.

Versatility in Food Storage

  1. Wide Range of Applications: Mylar bags are suitable for storing a variety of food items, including grains, legumes, dried fruits, nuts, seeds, spices, and dehydrated foods. They can also be used for packaging ready-to-eat meals, snacks, and emergency supplies, making them a versatile option for different storage needs.

  2. Space-Efficient: Mylar bags are lightweight and flexible, allowing for efficient use of storage space. They can be stacked, folded, or arranged in tight spaces, maximizing storage capacity and organization.


  1. Affordable Packaging Solution: Mylar bags are cost-effective packaging options, particularly when purchased in bulk quantities. Their durability, effectiveness, and long shelf life make them a worthwhile investment for both home and commercial use.

  2. Reduction of Food Waste: By extending the shelf life of stored foods, Mylar bags help reduce food waste and save money on replacement costs. This makes them an economical choice for preserving perishable items and minimizing food spoilage.

How to Choose the Right Mylar Bags

Selecting the right Mylar bags is essential to ensure effective food storage and preservation. In this section, we will discuss key factors to consider when choosing Mylar bags for your needs.

Thickness and Durability

  1. Thickness: Consider the thickness of the Mylar bags, typically measured in mils (thousandths of an inch), to ensure adequate durability and protection for your stored items. Thicker bags offer greater puncture resistance and durability, making them suitable for long-term storage and transportation.

  2. Durability: Choose Mylar bags made from high-quality materials with superior tear resistance and strength. Durable bags can withstand rough handling and adverse conditions without compromising their integrity, ensuring that your stored foods remain well-protected.

Size and Capacity

  1. Size: Select Mylar bags in sizes that accommodate the quantity and dimensions of the items you plan to store. Consider the volume of food to be stored and choose appropriately sized bags to prevent overfilling or underutilization of space.

  2. Capacity: Determine the capacity of the Mylar bags based on the weight or volume of the contents they can hold. Pay attention to the maximum weight or capacity specifications provided by the manufacturer to ensure optimal storage conditions and prevent overloading.

Sealability and Ziplock Options

  1. Sealability: Ensure that the Mylar bags have a reliable sealing mechanism, such as heat sealing or ziplock closures, to create an airtight environment that preserves freshness and prevents contamination. Test the sealability of the bags to ensure that they provide a secure and tight seal without leaks or gaps.

  2. Ziplock Options: Consider Mylar bags with ziplock closures for added convenience and ease of use. Ziplock bags allow for repeated access to the contents without the need for additional sealing equipment, making them ideal for storing items that require frequent opening and closing.

Transparency and Labeling

  1. Transparency: Choose Mylar bags with transparent or semi-transparent panels to allow for easy identification of the contents without the need to open the bags. Transparent bags enable quick visual inspection of stored items, facilitating organization and inventory management.

  2. Labeling: Look for Mylar bags that provide ample space for labeling with important information such as the contents, date of packaging, and expiration date. Proper labeling helps ensure efficient organization, rotation, and identification of stored foods, minimizing the risk of confusion or spoilage.

Preparing Food for Mylar Bag Storage

Properly preparing food for storage in Mylar bags is essential to ensure optimal freshness and longevity. In this section, we will discuss the steps involved in preparing food items before placing them in Mylar bags.

Properly Packaging Food Items

  1. Cleanliness: Before packaging, ensure that the food items are clean and free from any dirt, debris, or contaminants. Wash fruits, vegetables, and other produce thoroughly, and pat them dry with a clean towel to remove excess moisture.

  2. Dryness: Ensure that the food items are completely dry before packaging them in Mylar bags. Excess moisture can lead to mold growth and spoilage, compromising the quality and safety of the stored foods.

Removing Excess Air

  1. Air Removal: When filling Mylar bags with food items, take care to remove as much air as possible from the bags. Excess air can lead to oxidation and degradation of the stored foods over time.

  2. Vacuum Sealing: Use a vacuum sealer or manual method to remove air from the Mylar bags before sealing them. Press down on the bags to expel air and create a tight seal that prevents oxygen exposure.

Adding Oxygen Absorbers

  1. Purpose: Oxygen absorbers are packets containing iron powder that react with oxygen to create a vacuum-like environment inside Mylar bags. They help extend the shelf life of stored foods by reducing oxygen levels and inhibiting oxidation.

  2. Placement: Place one or more oxygen absorbers inside each Mylar bag before sealing it to remove residual oxygen and create an oxygen-free environment. Use the appropriate size and number of oxygen absorbers based on the volume and type of food being stored.

Steps to Store Food in Mylar Bags
