Which Balloons Are Best for Helium?

The best balloons for helium are high-quality latex and foil (Mylar) balloons designed to retain gas and float beautifully for hours. At One Up Party Balloons, we’ve tested thousands of helium-filled latex balloons and foil number balloons across Vancouver, Calgary, Edmonton, and Toronto. Here’s everything you need to know to keep your celebration floating high.

1. Latex Balloons (Best for Short-Term Events)

Latex balloons are made from natural rubber and expand beautifully when filled with helium. They’re perfect for birthdays, weddings, and same-day events. We use professional-grade 11-inch helium balloons that last 12–18 hours indoors and can be treated with Hi-Float to extend life up to three days.

Eco-friendly and biodegradable
Bright, vibrant colors available in matte, metallic, and chrome finishes
Ideal for balloon bouquets and arches

2. Foil (Mylar) Balloons (Best for Longevity)

Foil balloons are the top choice when you want helium balloons that last days or even weeks. They’re made of metalized nylon film, which traps helium far longer than latex. Our popular 34-inch gold number balloons and large letter balloons are perfect for birthdays, anniversaries, and corporate events.

Float 7–14 days with helium indoors
Reflective metallic surface adds elegance
Reusable and recyclable

3. Bubble Balloons (Best for Custom Designs)

Bubble balloons are clear plastic balloons that hold helium extremely well. They look like glass bubbles and can be filled with feathers, confetti, or mini balloons inside. They last up to two weeks and make stunning personalized gifts.

4. Best Practices for Helium Balloons

Inflate just before your event for maximum float time
Keep indoors at room temperature (avoid hot cars or direct sunlight)
Use Hi-Float gel for latex balloons to extend float time
Secure balloons with ribbon weights to prevent them from flying away
