LATEX BALLOONS: Long's Florist Supply offers 12-inch latex balloons in a variety of colors. Multicolored packs are also available in four different assortments. Each single color and assortment package includes 100 balloons.
Latex balloons -- the old-fashioned stretchy balloons you can blow up with lung power or helium -- are made from a liquid form of rubber. Inflated balloons made of this natural material contain tiny holes or pores that allow air inside to escape over time. Unlike Mylar balloons, latex balloons stretch and expand as they fill with air or gas. Filling a Mylar balloon, on the other hand, is more like filling a plastic bag with air -- stretching is minimal, if present at all.
