Simple & Easy Steps to Seal Mylar Bags with a Cloth Iron

Mylar bags are great for long-term storage and shelf presentation purposes. If you purchase a product packed in a resealable mylar bag and then it becomes non-operational, this can be intimidating. You may think of getting your food items spoiled and degrading the quality of your perishable products. This can be true, but if you learn the micro-skill of repacking these mylar pouches with the help of an iron, things will get much easier for you.

Yes, even if you haven’t tried this trick before, here in this blog, you’ll learn it from scratch and implement it in a hassle-free way. There’s no rocket science in it, all you need is:

• Mylar bags, the ones you want to seal.
• Clothes iron, either automatic or manual settings, no steam required.
• Oxygen absorbers are added to the pouches to absorb the oxygen.
• Flat surface that can be an iron-stand, a kitchen shelf, or a marble piece that can bear the heat of the iron.
• Permanent marker to mention the details about the product, e.g., name and date of packing.
• Scissors to trim the rough endings to get a professional look.

Practical Steps to Seal Any Mylar Bag with Iron

Once you’re ready, it’s time to follow practical steps to seal the mylar bag with perfection.

Step 1: Prepare the Space

First of all, make your space and ensure you have the necessary items at your bay. A rectangular or square-sized solid board is enough to perform this task without obstruction. While setting the iron to a medium setting, not high, nor low, as it will not bring the desired outcome. Also, it should be in dry mode, cotton settings at 400°C, as steam can melt down thesealable mylar pouch’s sheet.

Step 2: Fill the Bag with Content

Now, add the product you want to preserve, or if it’s already inside, let it settle down, and don’t pour away from the opening end. Add the oxygen absorber and then attach both sides. Press the empty area in a way that it pulls out the air outside, and there’s no room left behind.

Thus, seal the ends into two layers for a temporary seal to restrict the air passage and hold it by laying the bag down on a flat surface.

Step 3: Iron the Bag Shut

Thirdly, grab the iron in one hand and slide it from one corner of the pouch to the other. Move the iron slowly but not too slowly as it starts burning the mylar film. For thin mil layers, it will merely take a single slide of the iron. But for the thick layers, you may have to iron it more than once to ensure the ideal seal is developed.

Step 4: Recheck the Seal

That’s it! Now don’t touch the sealed area immediately, as it can be damaged. Wait for a while to let it cool down. After that, grab the pouch and keenly observe the sealed spot. If everything seems fine, you’re good to go. If not, then repeat the iron cycle again.

Lastly, you can perform two quick tests to check the seal’s strength. Either by squeezing the pouch to notice any leaks or dipping it in the water to see if any bubbles are escaping from the wrapped spot.

Situation to Benefit from Iron Sealing for Mylar Bags

There are multiple occasions when you use this DIY technique to reseal your perishable products if they are never unpacked. Some of the scenarios you may go through are:

• When the integrated seal got torn from its original placement, and even after closing it, the pouch remains open. For this, you can’t make the pouch function as new, but you can repack it smartly.
• When the zipper becomes dysfunctional and doesn’t work as it should. Rather than juggling with the zipper, it’s best to iron-seal it instantly to save your time and effort.
• If the pouch you’re using doesn’t have a resealability feature by default. Then you can utilize this method to also seal it like a new pouch. This will reduce your costs for packaging and also ensure that the product is packed in an air-tight environment.
