Think balloons are just for birthdays? Think again! Mylar balloons, those shiny, eye-catching floating decorations, are packed with more than helium—they’re full of history, science, and surprising uses. Whether you're planning a party or just love a good trivia fact, this article will change the way you look at these festive inflatables.
Let’s dive into some fun and unexpected facts about Mylar balloons, and we’ll also show you where to get the best ones—yes, we’re talking about the trusted House Of Party brand!
🎈 What Are Mylar Balloons Made Of?
You might think Mylar balloons are made of metal, but they're actually made from biaxially-oriented polyethylene terephthalate (or BoPET for short). It’s a kind of plastic that’s coated with a thin layer of metallic material, giving it that classic shiny finish.
This combo makes them:
-
Durable
-
Lightweight
-
Air- and helium-resistant
Unlike latex balloons, Mylar balloons can last days—even weeks—without deflating.
📜 A Little History: NASA Helped Create Them
Yep, NASA! Mylar was originally developed in the 1950s by DuPont, and it was used by NASA in space missions due to its heat resistance and strength. Before it was decorating your parties, Mylar was literally orbiting the Earth.
🎊 They Can Be Customized Like Crazy
From unicorns to wedding monograms, Mylar balloons come in just about any shape, color, or design you can think of. This makes them perfect for:
-
Birthday parties
-
Baby showers
-
Weddings
-
Graduation celebrations
-
Corporate events
Want custom messages or logos? House Of Party offers personalized Mylar balloons that are guaranteed to elevate your event.
💡 Fun Fact: Mylar Balloons Can Conduct Electricity
Be careful around power lines! Mylar is metallic, so if these balloons escape and hit electric lines, they can cause power outages. Always tie them securely and dispose of them properly.
🎨 Mylar Balloons Are Art-Friendly
Because of their flat, reflective surface, artists and event designers love using them for:
-
Photo backdrops
-
Party installations
-
Pop art and décor
They reflect light beautifully, giving your event that Instagram-worthy glow.
🕒 They Stay Inflated Much Longer Than Latex Balloons
On average, Mylar balloons stay afloat for 3 to 5 days, sometimes even longer with the right conditions. Latex balloons? They start to droop in hours.
Need your decor to last the whole weekend? Go with Mylar. House Of Party has long-lasting balloons perfect for extended events and outdoor use.
