How to Seal a Mylar Bag With Iron

Mylar is a type of polyester film made by DuPont and is often used to make storage bags because it is impermeable to air. This protects the contents of the Mylar bag much longer than traditional plastic storage bags. Mylar bags must be sealed to prevent air from entering the bag. A household clothes iron can be used to seal a Mylar bag for storage.

Things You'll Need

• Iron
• Ironing board

Instructions

1. Fill the Mylar bag. Shake the bag to allow the contents to settle to the bottom of the bag.

2. Flatten out the unsealed top of the bag on the ironing board.

3. Set the iron to the "Low" or "Cotton" setting. Run the iron across the top of the Mylar bag. Leave 2 inches of the top unsealed for now.

4. Squeeze out the excess air from the bag. Run the iron over the last 2 inches of the top left unsealed. The Mylar bag is now sealed.
