Foil/Mylar & Stretchy Balloons
Foil balloons and stretchy balloons are made from metalised nylon and a mix of other products. Though not biodegradable, some cities accept them into citywide recycling programs. These balloons can also be inflated, deflated, and reused!
Remember, the most important thing when using helium-filled foil or stretchy balloons is to weight them!
