Latex Balloons

Latex is the workhorse of balloon decorating — and for good reason. Available in 5", 11", 16", and 36" sizes across more than 50 colours, latex balloons give you the volume, versatility, and colour range that no other balloon type can match. Whether you're building a full organic garland for a wedding backdrop, clustering a handful of balloons above a birthday table, or filling a ceiling for a surprise party, latex is where you start.

For garlands and arches, the professional look comes from mixing sizes. A combination of 11" and 5" balloons in two or three anchor colours — with the occasional 16" balloon for visual variation — creates the lush, organic texture you see at styled events. Air-filled latex can be built days ahead without drooping, giving you scheduling flexibility that helium arrangements don't allow. When helium is the right choice, applying Hi-Float sealant inside each balloon before inflation extends float time from the standard 8–12 hours up to 25+ hours.

At Party Boutiques in Thornhill, we stock latex balloons individually and in bulk — so whether you need 20 for a backyard birthday or 500 for a venue installation, we have the inventory. We carry both standard and biodegradable latex options, and our team can advise on quantities, colour combinations, and inflation methods based on your specific setup.
