Easy Steps to Remove Air from Mylar Bags

Are you wondering how to remove air from Mylar bags? Whether you’re storing food for emergency preparedness or packaging products for long-term storage, keeping the air out of Mylar bags is essential. In this article, we will guide you through different methods and techniques to effectively remove air from Mylar bags, ensuring your items stay fresh and protected for extended periods.

Why Remove Air from Mylar Bags?

Before we dive into the methods, let’s understand why removing air from Mylar bags is crucial. The primary reason is to prevent oxidation and spoilage of the contents. Air contains oxygen, moisture, and various microbes, which can degrade the quality and shelf life of the products stored in Mylar bags.

Oxidation is a chemical reaction that occurs when oxygen comes in contact with certain substances, causing them to deteriorate or spoil. This process can lead to the loss of flavor, aroma, nutrients, and even the growth of harmful bacteria.

By removing air from Mylar bags, you create an oxygen-free environment that significantly slows down the oxidation process. This extends the longevity of food items, prevents spoilage, and maintains their nutritional value.

Method 1: Using a Vacuum Sealer

A vacuum sealer is a versatile and efficient tool for removing air from Mylar bags. It uses suction power to extract the air, creating a tightly sealed package that prolongs the freshness of the contents. Here’s how you can remove air from Mylar bags using a vacuum sealer:

  1. Gather your Mylar bags, vacuum sealer, and any items you want to store.
  2. Ensure the opening of the Mylar bag is clean and free from debris.
  3. Place the items you want to store inside the Mylar bag, leaving enough space at the top for sealing.
  4. Open the vacuum sealer’s lid and position the Mylar bag in the sealing chamber, aligning the opening with the machine’s sealing strip.
  5. Close the lid, ensuring a tight seal.
  6. Select the vacuum sealing option on the machine and wait for the air to be extracted from the bag.
  7. Once the air has been removed, the machine will automatically seal the bag. You can also manually press the seal button if needed.

Using a vacuum sealer is a quick and reliable method to remove air from Mylar bags. It’s ideal for storing a wide range of items, including dry food, spices, electronics, and more.

Method 2: Using an Oxygen Absorber

Oxygen absorbers are small packets that contain iron powder and salt. They are designed to absorb the oxygen present within a sealed environment like a Mylar bag. Utilizing this method alongside proper sealing techniques can effectively remove air and extend the shelf life of your stored items. Here’s how to use oxygen absorbers to remove air from Mylar bags:

  1. Assemble your Mylar bag, oxygen absorbers, and the items to be stored.
  2. Ensure the Mylar bag is clean and ready for sealing.
  3. Place the items inside the bag, leaving enough room at the top for sealing.
  4. Add the required number of oxygen absorbers based on the bag’s size and contents. Refer to the manufacturer’s guidelines for proper usage.
  5. Seal the Mylar bag tightly, ensuring no air can enter or escape.
  6. Store the bag in a cool, dry place away from direct sunlight.

Oxygen absorbers are an excellent option for long-term storage of food items, as they help maintain freshness and prevent the growth of mold, bacteria, and other harmful microorganisms.

Method 3: Manual Air Removal

If you don’t have access to a vacuum sealer or oxygen absorbers, manually removing air from Mylar bags is another effective option. Although slightly more time-consuming, it can still yield satisfactory results. Here’s how to manually remove air from Mylar bags:

  1. Select your Mylar bag, items for storage, and a straw or handheld pump.
  2. Ensure the Mylar bag’s opening is clean and ready for sealing.
  3. Place the items you want to store inside the bag.
  4. Leave some empty space at the top to facilitate air removal.
  5. Insert the straw or handheld pump into the bag’s opening, making sure to create a tight seal with your hand or an elastic band.
  6. Squeeze the bag gently to force air out through the straw or pump.
  7. Once the majority of the air has been expelled, quickly remove the straw or pump and immediately seal the bag tightly using heat, a bag sealer, or a twist tie.

Though this method may not completely eliminate all air, it significantly reduces the amount present in the Mylar bag, providing a reasonable level of protection for your stored items.

Conclusion

Properly removing air from Mylar bags is essential for ensuring the longevity and quality of your stored items. Whether you choose to use a vacuum sealer, oxygen absorbers, or opt for manual air removal, each method allows you to create a protective barrier against oxidation and spoilage. By following these techniques, you can confidently store food, electronics, and other products, knowing they will remain fresh and preserved for an extended period.

Remember, efficient air removal from Mylar bags is just one component of proper storage. Always consider additional factors such as temperature, humidity, and light exposure to enhance the overall longevity of your stored items.
