These bags can keep your food items for over a century if you can do it correctly. Yes, you read it right! To keep your food longer, you need to understand how to seal mylar bags properly. Let’s know more!

What is a Mylar bag?

Mylar packaging bags are solid storage bags to keep food items. In addition, these trendy bags come in a variety of sizes and are made of metalized polyester. These bags can contain dry foods or any food items that have a moisture content of 10% or less, with an appropriate amount of oxygen scavenger. The process of using these bags for long-term food storage can be seen as a quite simple one. Yet, it can also be prone to making mistakes that might then compromise your food preservation.

What Kind of Food Items Can You Store in Mylar Packaging Bags?

You can store various food items in mylar packaging bags by filling them first with an oxygen scavenger. As mentioned above, the kinds of food items you can store must be dry foods with a moisture content of 10% or less. Meanwhile, some oily foods cannot be stored in these bags containing oxygen scavengers. The types of dry foods that you can keep in these bags include:

  • Whole grain products except barley and brown rice
  • White rice
  • Oatmeal
  • All-purpose flour and bread crumbs (both disinfected with bran and germ)
  • All types of beans

Add Oxygen Scavenger/Desiccant before Sealing Mylar Bags

Yes, to seal your mylar bags, you will need to add an oxygen scavenger. What is that? Oxygen scavenger does precisely what it sounds like; it takes in oxygen.

So the idea here is to add an appropriate amount of oxygen scavenger to the Mylar bag before sealing it. As soon as the bag is sealed, the oxygen scavenger will start to draw oxygen from the air. This process is quite essential because oxygen is one of the factors that can significantly shorten the shelf life of food.

Remember, you will need to determine the correct amount of oxygen scavenger. If not added enough, you might mistakenly add harmful oxygen that can damage the food items. Even worse, if you add too much oxygen, you will only waste more money.

How to Seal Mylar Bags Properly

How to Seal Mylar Bags Properly

Now that you have your Mylar bag, oxygen scavenger, and food items, you will need one more item. To be noted, proper heat resembles a good seal. In this case, proper heat will be essential for the long-term protection of your food inside the bag. In fact, if you are unable to get the seal correctly, your food will not last long. In this context, you should never make any mistake.

To help you out, try out the steps below to guide you how to seal mylar bags properly.

The mylar bag should be perfectly flat, 100% clean, and at the right temperature

If you seal the bag and it is not flat, you will not get any reliable seal. Sealing works because when heat is applied to the bag, the Mylar’s material will start to melt. If both sides of the bag are melting, they can mix. The next thing you will have to do is removing, the heat. By removing the heat, you will make the soft melted material back to being solid. In fact, this is exactly the purpose of your seal actually.

So in case you are trying to get both sides of your bag and melt them together, you might cause a wrinkle. This wrinkle will then create a pocket of air to enter the equation. The bad thing from this is that this pocket will reduce the effectiveness of the seal on the bag. In the end, even if your seal seems good at first, it will be weak at the wrinkle location. Over time, this vulnerability might collapse.

Get rid of the external matters

The following key to a good seal is to get rid of all the external matters. Some small particles of food or dust in the seal have the chance to compromise its integrity. When there is a presence of food particles in the gasket, it will reduce the mylar-to-mylar contact by introducing external matter amid the gaskets. This would not be good.

Heat control

The third sealing option you can choose for reliable sealing is heat control. If you didn’t apply proper heat, the material of your mylar packaging bags would not dissolve completely. Too much heat will melt the holes in the gasket. Yes, the seal is sticky and may function to hold. On the other hand, it might not be able to be completely locked to its intended strength. So, make sure to go for the proper heat control as it is well worth every penny.

If you are thinking of going with a cheaper device, you can try using a clothes iron or even a good quality hair straightener. These items will work for sealing your mylar packaging bags as well. However, do remember that you will need to do some testing to assure that the seals will hold the food proeprly.

Consider using vacuum sealer to seal your mylar bags

Without you realizing it, a vacuum sealer will work very well in removing the excess air from your bags while sealing them. However, the only problem might be that the mylar bag is smooth. Thus, the indentation is essential for the vacuum sealer to be effective.
