Known for their exceptional barrier properties and durability, Mylar bags can protect contents from moisture, light, oxygen, and pests.

In this blog post, we'll share tips and best practices for using Mylar bags for long-term storage.

Why Choose Mylar Bags for Long-Term Storage?

Mylar bags offer several benefits that make them ideal for long-term storage:

  • Moisture Resistance: Mylar bags create an effective barrier against moisture, preventing mold and spoilage.
  • Oxygen Barrier: These bags keep oxygen out, which is crucial for preserving the freshness and quality of products.
  • Light Protection: Mylar bags block harmful UV rays that can degrade the contents over time.
  • Pest Deterrence: The durable material and tight seals keep pests away from your stored items.

Tips for Using Mylar Bags for Long-Term Storage

1. Choose the Right Thickness

  • The thickness of Mylar bags is measured in mils. For long-term storage, it’s recommended to use bags that are at least 5 mils thick. Thicker bags provide better protection against punctures and environmental factors.

2. Proper Sealing Techniques

  • To ensure your Mylar bags are airtight, use a heat sealer to seal the bags properly. A high-quality heat sealer will create a strong, consistent seal that prevents air and moisture from entering.

3. Include Oxygen Absorbers

  • Oxygen absorbers are essential for long-term storage as they remove residual oxygen from the bag. Place the appropriate number of oxygen absorbers inside the bag before sealing. The amount needed depends on the size of the bag and the type of product being stored.

4. Store in a Cool, Dark Place

  • For optimal preservation, store Mylar bags in a cool, dark place. Exposure to heat and light can degrade the contents over time, so choose a storage area that is consistently cool and dark.

5. Label Your Bags

  • Clearly label each Mylar bag with the contents and the date of storage. This will help you keep track of what’s inside and how long it has been stored, making it easier to manage your inventory.

6. Use Appropriate Bag Sizes

  • Select bag sizes that match the quantity of the product you’re storing. Using appropriately sized bags minimizes excess air and helps maintain the integrity of the seal.

7. Check for Leaks

  • After sealing, inspect the Mylar bags for any potential leaks or weak spots. Press gently on the bag and listen for any air escaping. A leak-free seal is crucial for long-term storage.

Best Practices for Specific Products

Food Items

  • Grains and Legumes: Store dried grains and legumes in Mylar bags with oxygen absorbers to prevent spoilage and insect infestation.
  • Dehydrated Foods: Dehydrated fruits and vegetables can be stored for years in Mylar bags, maintaining their nutritional value and flavor.

Herbs and Spices

  • Protect herbs and spices from moisture and light to preserve their potency and flavor. Mylar bags with resealable zippers allow for easy access while maintaining freshness.

Emergency Supplies

  • Mylar bags are ideal for storing emergency supplies such as medical kits, batteries, and important documents. Their durability ensures that your supplies remain intact and accessible when needed.
