How Are Party Balloons Made?
The balloons you see at a birthday party or a circus began as latex, the milky liquid of rubber trees, and can be filled with air, helium, water, or any other suitable liquid or gas. The rubber’s elasticity makes the volume adjustable.
Most party balloons are made in Mexico. In the balloon factory, workers dip balloon-shaped molds into vats of brightly colored liquid latex. The latex dries on the molds in the shape of deflated or uninflated balloons.
The molded latex is then dipped in a talcum powder solution to keep the balloons from sticking together when packaged. Next, the balloons are heated to make the rubber strong.
Workers peel the finished balloons off the molds, then sort and package them for market. They can come in different colors like the rainbow such as red, orange, yellow, green, blue, purple, etc.
