Common questions

Frequently Asked Questions

What's the difference between foil and mylar balloons?

Mylar is a DuPont brand name for polyester film, but in the balloon industry the terms are used interchangeably. Most Chinese factories use BOPP (biaxially oriented polypropylene), not true Mylar brand polyester.

Can you make custom-shaped foil balloons?

Yes. Custom die-cut shapes require a cutting die (tooling cost approximately $100–300) and MOQ typically 5,000–10,000 pieces. Any shape can be produced — send a reference image for feasibility review.

How long do foil balloons float?

3–7 days with helium, significantly longer than latex (8–12 hours). Foil balloons can be deflated using a straw in the valve and re-inflated multiple times.

Are foil balloons recyclable?

Foil balloons are not biodegradable and are not accepted in most curbside recycling programs. They are a plastic product. For buyers with sustainability requirements, latex balloons are the biodegradable alternative.
