Quick Answer
Vacuum sealing Mylar bags is optional for storage longevity, but it provides the best protection against moisture, pests, and air exposure, ensuring a shelf life of up to 25 years or more.
Importance of Moisture Control
When storing food in Mylar bags, moisture is a significant concern. Mylar bags are impermeable to air and water vapor, but they can still absorb moisture from the surrounding environment, leading to spoilage and degradation of stored food. Vacuum sealing Mylar bags removes the air and water vapor inside the bag, creating a vacuum that prevents moisture from entering. This process can be done using a food sealer or a DIY vacuum sealer setup.
Techniques for Vacuum Sealing Mylar Bags
To vacuum seal Mylar bags effectively, it’s essential to follow a few best practices. First, ensure the Mylar bag is properly sealed with a heat sealer or a strong adhesive. Next, use a food sealer or a DIY vacuum sealer setup to remove the air from the bag. A good rule of thumb is to remove 99.5% of the air to ensure a tight seal. To achieve this, you can use a vacuum sealer with a gauge that shows the vacuum level. Some popular vacuum sealers can pull down to 28 inches of mercury (inHg) or lower.
Benefits of Vacuum Sealing Mylar Bags
Vacuum sealing Mylar bags provides several benefits for long-term food storage. By removing air and moisture, you can extend the shelf life of stored food to 25 years or more. Additionally, vacuum sealing prevents pests and rodents from accessing the stored food, reducing the risk of contamination and spoilage. With proper vacuum sealing techniques and equipment, you can enjoy a worry-free food storage experience, knowing that your stored food will remain fresh and safe for consumption.
