How Can I Make a Mylar Balloon?by Chelsea Hoffman
Commonly called Mylar, stretched polyethylene terephthalate serves as a strong and durable material for a variety of applications from industrial to arts and crafts. Making a Mylar balloon proves easy with this material and it allows you to create one-of-a-kind accents to balloon bouquets or other crafts. Whether you're filling it with helium or just air, making a Mylar balloon is a creative task that can be completed in very little time.
Place a circle stencil measuring about 12 inches across over a 24 square inch sheet of Mylar plastic.
Trace the circle outline with a black marker and then cut it out of the Mylar plastic. Repeat these steps until you have two circles of Mylar each measuring about 12 inches in diameter.
Place one of the circle sheets of Mylar plastic down and ease out the wrinkles or creases in it so that it is completely flat and smooth. If you are using a colored type of Mylar, make sure the colored side is facing upward.
Squeeze a line of hot glue along the circumference of the Mylar. Leave about a two inch gap unglued on the circle.
Layer the second Mylar circle over the first, pressing the edges together firmly. Make sure you place the colored side of the top layer downward, facing the other colored part of the plastic. Let the pouch of plastic dry for about 20 minutes.
Slip the plastic pouch inside-out. This conceals the glued edges and turns the colored sides of the Mylar plastic so that they face outward.
Fill the balloon by nozzle with helium or air. Squeeze the opening of the balloon closed around a small dot of hot glue to secure the air within the balloon.
