We’ll also talk about Mylar bags and their benefits. If you’re interested in learning all these aspects, then let’s get started!

What are Mylar Bags?

Mylar bags, which are made of laminated food-grade plastic and aluminum, have been widely used for preserving foods and other goods over long periods. They are often used to store food because they block out light, moisture and oxygen.

Heat-sealed bags create an impermeable and airtight environment, protecting the contents against external elements. Mylar bags are available in different sizes, and they're great for preserving food over time. Brands like Wallaby provide high-quality Mylar bags designed to keep food fresh and maintain its texture, taste, and nutritional value for many years.

Mylar bags are the superior storage method for long term freshness. They provide several benefits, including: 

• Protection from Moisture: Mylar bags made by Wallaby, are ideal for preventing moisture in stored foods. Moisture resistance prevents mold growth and ensures that your food is safe to consume.
• Oxygen barrier: Mylar bags are known for their ability to slow down the oxidation process by blocking oxygen. The process preserves the nutrients and flavor of food and keeps it fresher for longer. Wallabies are designed to have an oxygen barrier that maximizes food life.
• Light protection: Exposure to sunlight can cause food to degrade, particularly vitamins C and A. Mylar bag is designed to keep food fresh and nutritious for a longer period.
• Pest Protection: Mylar bags are a barrier that prevents pests like insects and rodents from reaching food. Mylar bags provide superior protection to ensure your food remains safe during storage.
• Shelf-Life When properly sealed, Mylar Bags from Wallaby will extend food's shelf life. They are ideal for bulk storage or emergency preparation.

Common mistakes and how to avoid them

These mistakes include improper sealing, incorrect oxygen absorption, excessive moisture, and inadequate storage. They can lead to food spoilage. Avoiding these mistakes is essential to ensuring successful food storage. We'll look into these issues in detail.

1: Mylar bags sealed incorrectly

Sealing errors are one of the most common problems that people face when using Mylar. It is important to have a tight seal on the bag in order to prevent moisture, pests, or air from entering.

Mylar seal errors can be caused by incorrect sealing techniques, inadequate heat or even defective equipment. Your food will spoil faster if the seal on your bag isn't done correctly.

What is the Correct Way to Seal Mylar Bags?

• Use a Mylar sealing machine, or impulse sealer, that is specifically designed for Mylar bags to ensure proper sealing. They provide a consistent amount of heat, ensuring a tight seal. If you use a household iron instead, it may not produce an even amount of heat and cause a weak seal.
• Use a sealer that is designed for sealing with a straightener if you are doing it by hand. After sealing the bag, test it by pressing down on it. Seals that leak air are not sufficiently tight. You will need to seal the bag again.
• Make sure you leave space on top of your Mylar bag to accommodate the oxygen absorber as well as any expansion. 

2. Air Leaks from Mylar Bags

When food spoils prematurely, air leaks from Mylar bags can be a problem. An improper seal is one of the most common causes. Checking for tears or punctures that could allow air to enter Mylar bags is also important.

What to do in case of a Mylar Bag Air Leak?

• Always inspect bags prior to sealing. Check for any visible tears or punctures that may have been caused by handling. 
• Store Mylar bags cool and dry to avoid damage from sharp objects, rough treatment, temperature changes, or other factors.
• To protect your bags from damage, you can place them in buckets that are suitable for food. This will prevent any physical damage to the bags and keep them intact. It's especially important to use this extra layer of protection if your bags are being stored in an area where temperatures can vary, such as a basement or garage.

3. Mylar bags moisture problems

Food spoilage is often caused by moisture. Moisture in sealed Mylar bags can cause mold to grow and food spoilage. Moisture issues in Mylar bags can occur when you store food. This is due to improper sealing, excessive humidity or the failure to use oxygen-absorbing agents.

What to do if Mylar bags are damaged by moisture?

• Always make sure that the food you are storing is completely dry before sealing the bag. 
• Place oxygen absorbers in each Mylar bag. This will remove oxygen, which can lead to condensation or moisture. 
• Oxygen bag mistakes are usually caused by using either too many oxygen absorbers or not enough.
• You will need to determine the number of oxygen-absorbing bags you require based on how much food is in your bag and also the size of that bag. 
• Typically, a 300-cc oxygen absorber is usually enough for a Mylar bag that holds 1-2 gallons. You should adjust your oxygen absorber number if you are storing bulk food.
• To prevent moisture from entering the sealed bags, it's important to keep your Mylar bags away from direct sunlight or humidity.

4. Using Oxygen Absorbers Effectively

They help prevent food spoilage by removing excess oxygen. Mylar bag's oxygen absorbers are frequently overlooked. For a more detailed explanation on how oxygen absorbers work and how to use them effectively, check out this helpful guide on  oxygen absorbers.

What to do if your Mylar bag Oxygen Absorber is not working properly?

The wrong type or size of oxygen absorber may lead to spoilage and inefficient storage. Use oxygen absorbers designed specifically for Mylar bags. These packets may become moistened by overuse or misuse, which can lead to mold and bacteria growth. Check the expiration date of oxygen absorbers prior to use and keep them sealed in an airtight container.

5. Mylar bags deterioration

If Mylar bags have not been properly sealed or are subjected to extreme temperature changes, deterioration can result. When using Mylar, it is important to keep in mind that storage conditions are crucial. Mylar food bags can have problems even with proper sealing if they are kept in an area that is either too warm or too cold.

How to store Mylar bags for long-term storage?

• Place your Mylar bags somewhere cool and dry that has a constant temperature. 
• Store them away from areas that are prone to extreme temperatures, like near heaters and unventilated lofts. 
• Store dry foods in Mylar in dark and cool environments like the basement or pantry for longer-term storage.
• Don't store your bags directly on the floor, as they may be subject to moisture.
• Place them instead on shelves in order to keep them away from moisture.
  

6. Mylar bag seal failures

Mylar bags can have problems sealing even with all precautions. When the seal breaks after a bag is stored, this can be a common problem. It is usually caused by incorrect sealing, inadequate seal equipment or storage damage.

How to Troubleshoot Mylar Bags

Reseal the bag as soon as you can if it has an imperfect or broken seal. You can use a Mylar sealer or heat-sealing device to reseal if the contents are still edible. To prevent contamination, throw away the food if it is spoilt. Before resealing the bag, inspect it carefully for signs of tears or punctures.

Best Practices for Mylar Bag Food Storage

Here are some tips to help you avoid the most common mistakes when using Mylar bags for food storage.

• Proper sealing: Always make sure that the seals are airtight.
• Use Oxygen Absorbers: Place one oxygen absorber per bag to prevent oxygen exposure.
• Dry food first: Make sure that the food has been completely dried before it is sealed in a bag.
• Examine Bags Regularly. Check Mylar bags for punctures, leaks or improper seals.
  For best results, store Mylar bags in cool, dark, and dry.
