How to Seal Mylar Bags for Food Storage

Mylar bags are an excellent option for long-term food storage, as they provide a barrier against oxygen, moisture, and light, which can help to preserve the quality and nutritional value of food over extended periods. Properly sealing mylar bags is crucial to ensure the integrity and effectiveness of food storage. Here are the steps involved in sealing mylar bags for food storage:

  1. Choose High-Quality Mylar Bags: Select food-grade, resealable Mylar bags suitable for long-term storage. Ensure that the bags are free from holes or tears.

  2. Prepare the Food: Before placing food in the mylar bags, ensure that it is clean, dry, and properly packaged in smaller, airtight containers to prevent exposure to oxygen. Remove as much air as possible from each inner container before sealing.

  3. Add Oxygen Absorbers: Include oxygen absorbers inside each mylar bag to remove any residual oxygen. Follow the recommendations on the oxygen absorber package for the appropriate amount to use based on the bag size and the quantity of food.

  4. Fold the Bag and Heat-Seal: Fold the top of the mylar bag down several times to create a seal. Use a heat sealer specifically designed for mylar bags to seal the bag. Ensure that the seal is complete and airtight, leaving no gaps or openings.

  5. Perform a Seal Test: To verify the integrity of the seal, conduct a seal test by immersing the sealed bag in water and observing for any air bubbles escaping. If bubbles are visible, the seal is not airtight, and the bag should be resealed properly.

  6. Label the Bag: Label each mylar bag with the contents, date of packaging, and any other relevant information to help you easily identify and track the stored food.

  7. Store in a Cool, Dry Place: Keep the sealed mylar bags in a cool, dry place away from direct sunlight, extreme temperatures, and moisture. Consistent conditions are ideal for maintaining the integrity of the food over time.

By following these steps and using high-quality materials, you can effectively seal mylar bags for long-term food storage, preserving the quality, flavor, and nutritional value of your stored food for extended periods.
