Mylar bags make food storage convenient and easy. They are great for storing food, seeds, herbs, and other items that need protection from moisture, oxygen, and light. They are also durable, reusable, and easy to label. But how do you seal them properly? That's where a heat impulse sealer comes in handy. A heat impulse sealer uses a short burst of electric current to heat a metal wire and create a strong seal on the edge of the bag. It's fast, efficient, and convenient.

Here are some ways to use it to pack your Mylar bags:

The Basic Method:

This is the simplest way to seal your Mylar bags. Just plug in your heat impulse sealer, adjust the timer according to the thickness of the bag, and place the open end of the bag between the jaws of the sealer. Press down firmly until the light goes off, and voila! You have a sealed bag. Make sure to leave some space at the top of the bag for air to escape when you press down.

The Vacuum Method:

This is a more advanced way to seal your Mylar bags to remove most of the air inside the bag. This helps preserve the freshness and quality of your items for longer. To do this, you need a vacuum pump or a vacuum hose attachment for your sealer. First, fill your bag with your items and leave some space at the top. Then, insert the vacuum hose into the bag and turn on the pump. The air will be sucked out of the bag and create a tight fit around your items. Once you have achieved the desired level of vacuum, quickly seal the bag with your heat sealer.

The Oxygen Absorber Method:

This is another way to remove oxygen from your Mylar bags and extend their shelf life. Oxygen absorbers are small packets that contain an iron powder that reacts with oxygen and creates rust. They are safe and effective for storing food and other items that are sensitive to oxygen. The oxygen absorbers will absorb any remaining oxygen in the bag and create an inert atmosphere.

These are the best ways of using heat impulse sealers to pack Mylar bags.
