What Are Mylar Bags and Why Use Them?

Mylar is a type of polyester film made from stretched polyethylene terephthalate (PET). It’s characterized by its excellent oxygen barrier properties, making it ideal for vacuum-sealed storage. When combined with oxygen absorbers, mylar bags create an anaerobic (oxygen-free) environment that significantly slows down the spoilage process in dried foods.

Some key advantages of using mylar bags include:

  • Blocks out light, moisture, and oxygen to prevent nutrient degradation
  • Provides outstanding protection against insects, rodents, and other pests
  • Helps preserve flavor, aroma, and texture of dried goods
  • Resistant to punctures and tearing for long-term food storage
  • Compact and space-efficient compared to bulky buckets or cans

By removing oxygen and moisture from the equation, mylar bags allow preppers to safely stockpile grains, beans, dehydrated meals, and other essentials for emergency scenarios.

Factors to Consider When Choosing Mylar Bags

Not all mylar bags are created equal. To ensure your investment pays off, there are several key factors to evaluate:

Thickness and Durability

Mylar thickness is measured in mils, with 1 mil being 1/1000 of an inch. The thicker the material, the more durable and puncture-resistant the bag will be. Most food-grade mylar bags range from 3.5 mils to 7 mils in thickness.

ThicknessDurabilityLight Blocking
3.5 milAverageGood
5 milHighExcellent
7 milExceptionalExcellent

Size and Capacity

Mylar bags come in a wide range of sizes, from small pouches ideal for herbs and spices to large 5+ gallon bags built for serious bulk storage. Consider your inventory needs and space constraints when selecting sizes.

SizeBest For
Up to 1 gallonIndividual meal portions, snacks, loose items
1-2 gallonsStandard pantry items, grains, beans
3-5 gallonsLarge quantities, bulk foods
5+ gallonsMajor staples, long-term stockpiling

Sealability

An airtight seal is absolutely critical for preserving food in mylar. The sealing method and quality of the bag material both impact sealability. Look for bags designed for easy heat sealing or those with ziplock-style closure systems.

Oxygen Barrier

The entire purpose of mylar storage is to eliminate oxygen exposure. Pay close attention to the oxygen transmission rate and oxygen barrier capabilities claimed by different brands. The lower the rate, the better.

Reusability

Some preppers prefer reusable mylar bags with resealable closures. This allows you to open and reseal bags as needed without compromising the contents. Others opt for single-use bags to avoid contamination risks.

Accessories Included

Many mylar bag offerings come packaged with useful accessories like oxygen absorbers, humidity test cards, and printed labels. These can provide added value and convenience.

Price

As with any purchases, price is always a factor. However, beware of cutting costs at the expense of quality – higher-end mylar bags do tend to perform better in the long run.

Brand Reputation and Reviews

Research various brand reputations and read consumer reviews carefully. This can provide insights into real-world performance, customer service, and value for money.

Mylar Bag Sealing Techniques

Proper sealing is absolutely vital when using mylar bags, as even a tiny pinhole can compromise an entire bag’s contents over time. There are a few different techniques to create an airtight seal:

  • Heat Sealing: Using an impulse sealer, a heated wire melts the two sides of the bag together to fuse them shut. This is considered the most reliable sealing method.
  • Iron Sealing: You can also use a standard clothes iron on its highest setting to flatten and melt the bag’s seal area. Tricky but doable without special equipment.
  • Zipper Locks: Some mylar bags incorporate reusable zipper or plastic zipper locks into the design. These are handy for frequently accessing contents while still maintaining an airtight seal.

For best results, ensure the sealing area is clean and free of debris or wrinkles. Always add oxygen absorbers prior to sealing. A quality mylar bag sealer designed specifically for this purpose is a worthwhile investment for preppers.

Integrating Mylar Bags into Your Preparedness Plan

Once you have your mylar bags selected and sealed, organizing them into your overall emergency survival strategy is crucial. Here are some tips:

  • Establish a Rotation System: Clearly label all bags with packing dates. Set reminders to cycle through and consume the oldest bags first to avoid expiration.
  • Create Storage Levels: Use larger mylar bags for storing bulk foods, while smaller pouches hold portions ready for bug out bags or short-term use.
  • Combine with Other Methods: Mylar bags pair very well with food-grade buckets, cans, ammo boxes, or bins for added protection and easy stacking/storage.
  • Pack Bug Out Bags and Kits: Have lightweight, calorie-dense survival supplies like energy bars, trail mixes, and dehydrated meals pre-bagged in mylar for grab-and-go kits.
  • Consider Accessibility: Place most frequently accessed foods towards the front of your pantry or storage area.

Tips for Maximizing Shelf Life

Even with top-quality mylar, there are crucial steps to ensure your food lasts as long as possible:

  • Control Temperature & Humidity: Cool, dry, and dark environments help prevent spoilage and maintain nutrition levels. Around 60°F and 15% humidity is ideal. Learn more about temperature control in food storage.
  • Use Oxygen Absorbers Properly: Oxygen absorber packs should always be added right before sealing. Follow package directions for correct quantity based on bag size.
  • Prioritize Labeling: Clearly label each bag’s contents, packing date, and expected expiration. This aids with rotation and avoids mix-ups.
  • Keep an Inventory: A detailed log helps you track what you have and restock in a timely manner. Check for signs of deteriorating bags as well.
  • Inspect Bags Regularly: Look for any punctures, leaks, or condensation inside bags that could indicate a compromised seal.

Conclusion

In the world of emergency preparedness and long-term food storage, mylar bags are an indispensable tool. Their superior oxygen barrier and protection against environmental factors allow you to stockpile a sustainable food supply for years to come.

When selecting mylar bags, be sure to consider aspects like thickness, size, included accessories, ease of sealing, and overall quality. Pay close attention to reputable brands and reliable consumer reviews as well.
