 What Exactly is a Mylar Bag?


Mylar, a brand name for a special type of polyester film, has become synonymous with durable food storage solutions. These bags are celebrated for their exceptional barrier properties against oxygen, moisture, and light – the three arch enemies of long-term go-to food preservation. By effectively blocking these elements, Mylar bags protect foods from spoilage and extend their shelf life exponentially, making them a go-to choice for dry goods storage.




The Critical Step of Sourcing Safe Mylar Bags


The market is full of offerings for Mylar bags, but not all are suitable for food storage. The safety of your stored food hinges on the quality of the bags you use. A significant concern is the proliferation of counterfeit or low-quality bags, especially those from dubious sources, even when sold on reputable sites online. These bags may not offer the same level of protection, may degrade over time, or, worse, could contaminate your food with harmful chemicals.


To navigate these waters safely, prioritize purchasing Mylar bags from reputable suppliers. These vendors should provide comprehensive product details, including the material composition and safety certifications. Furthermore, they should be transparent about their manufacturing processes and quality control measures. Engaging with a community of food storage enthusiasts can also offer valuable insights and recommendations.



The Importance of Thickness in Mylar Bags


The thickness of a Mylar bag is a key determinant of its suitability for various storage needs, measured in mils (thousandths of an inch). The range typically spans from 3.5 to 7 mils, with each thickness tailored to different storage conditions as follows:


 3.5 to 4.5 mil bags are your lightweight champions, perfect for the short-term storage of foods like spices, teas, and snacks. Their thinner profile makes them less ideal for hiking or long-term scenarios, but excellent for everyday kitchen turnover. These are perfect when you need storage for just a couple of months.


 5 to 6 mil mylar bags strike a happy medium, offering increased durability without significant bulk. This makes them versatile warriors against time, suitable for a broad array of dry goods, from nuts and seeds to powdered milk and grains. 5 mil bags will store your food for around a year.


7 mil bags are the heavy-duty protectors of your pantry. Designed for the longest shelf life and toughest conditions, these bags are best suited for your long-term food storage strategy. Most bulk food that you're banking on for years, can be stored for up to 25 years in these bags, assuming your food is properly preserved, and the bags properly sealed and stored.


But know this: Many inexpensive mylar bags sold online and advertised as 5 mil or 7 mil bags are 2.5 or 3.5 mil per side- so they are NOT suitable for long-term storage. Quality bags are 5 mil or 7 mil per side. Remember, you get what you pay for!



 Step-by-Step Guide to Using and Sealing Mylar Bags


1. Preparation: Begin by choosing the right size bag for your needs and ensure it's clean and dry.


2. Filling: Add your food items to the bag, being careful not to overfill. Leave enough space at the top for a proper seal.


3. Oxygen Absorbers: Place an appropriately sized oxygen absorber inside the bag to prevent oxidation and extend shelf life.


4. Sealing: Using a flat iron, hair straightener, or a dedicated Mylar bag sealer, press firmly along the open edge to create an airtight seal. Ensure the seal is uniform and complete.


5. Labeling: Mark each bag with the contents and the date of packaging to keep your storage organized.


6. Inspection: After sealing, allow the bags to sit in a stable environment for about a week. This period lets you check for potential leaks, which can sometimes be resealed.



 Conclusion


Armed with the right knowledge and tools, Mylar bags can be a game changer in your food storage strategy. They not only offer peace of mind through the preservation of food quality and nutritional value but also contribute to a sustainable lifestyle by minimizing waste. By understanding the nuances of bag thickness, mastering the sealing process, and ensuring the quality and safety of your bags, you'll be well on your way to achieving food storage mastery.


Embrace this journey with confidence, knowing that each step you take towards mastering Mylar bag storage is a step towards self-reliance and sustainability.
