Find the inflation hole on the surface of the balloon. All aluminum balloons have a small hole with a diameter of 2.5 to 5 cm, which is specially used for inflation. This hole is usually near the bottom of the balloon surface and covered with 2 or 3 layers of plastic paper. The inflation hole is probably where ordinary balloons are tied with ropes.

Separate the two layers of plastic film and insert the straw until the sealing layer is punctured. When the straw enters 2.5 to 5. 1cm, the sealing layer can be touched. Hold the suction pipe and the inflation hole by hand to prevent air from escaping. In order to fix the straw when inflating, it is necessary to hold both sides of the straw with two thumbs. Never let go when there is inflation.

Then use the end of the straw to blow into the balloon. When it is full, pull out the straw, pinch the inflation hole tightly and seal it. In this way, the inflation of the aluminum foil balloon is completed.

Production of aluminum foil balloons really started in the late 1970s. In the past, people always wanted to develop a balloon that can keep the gas from leaking for a long time and bear the weight of children because children play with latex balloons and the gas retention time is short.

Finally, aluminum foil was discovered in the late 1970s. The surface printing of these produced aluminum foil balloons not only looks very beautiful, but also can produce aluminum foil balloons of various sizes and shapes. Once the product came out, it was deeply loved by people.
