Is It Safe to Store Food in a Garage Using Mylar Bags?

April 5, 2026

Quick Answer

Storing food in a garage using Mylar bags is generally safe if the environment is controlled and meets specific conditions, but it's not suitable for extreme temperatures, moisture, or pests.

Garage Storage Considerations

When using Mylar bags for food storage in a garage, it’s essential to maintain a consistent temperature between 50°F and 70°F (10°C to 21°C) to prevent moisture buildup and spoilage. Ensure the garage is well-ventilated to prevent the accumulation of moisture and carbon dioxide produced by stored food.

Mylar Bag Filling and Sealing Techniques

Properly filling and sealing Mylar bags is crucial for safe food storage. Fill Mylar bags to the recommended 2/3 capacity to allow for expansion and prevent over-pressurization. Use a FoodSaver or similar vacuum sealer to remove air from the bag, and then use a heat sealer or iron to create a tight seal. This will prevent moisture from entering the bag and extend the shelf life of stored food.

Garage Storage Setup and Maintenance

To create a suitable garage storage environment, consider using shelving and storage containers to keep Mylar bags off the floor and elevate them at least 6 inches (15 cm) above the ground. Regularly inspect the stored food for signs of spoilage, and check the garage temperature and humidity levels to ensure they remain within the recommended range.
