Causes of a balloon leak

I have encountered many customers asking why the balloons ordered in other factories are leaking so badly. Some of them deflated or not floated after one day after being filled with helium. They asked

There are many reasons for the air leakage of aluminum film balloons, the most important of which are as follows:

1. The influence of temperature difference. I have done an experiment. In an environment of 34 degrees Celsius, 10 balloons were filled with helium, and then placed in an environment of 24 degrees. After 1 or 2 hours, 10 balloons looked obviously deflated. Said that he didn't look full when he was just inflated, but it still floated. On the contrary, put these 10 balloons in an environment of 34 degrees Celsius and they will bulge again after one or two hours. Therefore, temperature still has an effect on air leakage. Of course, this is only the principle of thermal expansion and contraction. I will not repeat the principle of thermal expansion and contraction. So when we inflate and use aluminum balloons, we try to choose the same environment as possible.

Second, the impact of materials, usually when customers inquire about the quality standard to be exported or general quality requirements. If the customer is exporting to Europe and the United States, we generally recommend that the customer use nylon material. The relative tightness and fastness of nylon material are better than PET materials, and the touch is relatively soft. Of course, the relative price will be a little more expensive. And if the customer's quality requirements are not very high, and the price is cheap, we will tell the customer to use PET as the material. Compared with nylon, the gas retention and fastness of PET will be worse.

3. The influence of the production process. So far, the production of aluminum film balloons has two production processes, one is cold trimming and the other is hot trimming. Domestic manufacturers use cold cutting technology to produce aluminum film balloons. The cold cutting technology only has one seal. The cutting edge is cold cut to cut out the shape of the aluminum film balloon. Its sides are not sealed. Its advantage is the speed of production. Faster, the relative production cost will also be reduced. If foreign customers really understand aluminum foil balloons, they will choose the hot-trimming production process, because the hot-trimmed aluminum foil balloon has a seal on the side, that is to say, there are two seals to prevent helium. It leaks from the side seal.

Fourth, the influence of inflation pressure, when we inflate the aluminum foil balloon, try to be enough at one time, don't worry about the balloon bursting, then how do we judge whether the balloon is sufficient? When we inflate, it is already very hard to touch the balloon with one hand. It means that there is enough, or just drop the inflated balloon on the ground and just hear the booming sound. So why do we need to be sufficient when we inflate the balloon for the first time? Our current balloons are all automatic The sealed air nozzle. When we inflate the balloon, the gas will pass through the automatic sealing mouth. After it is inflated, it will have a gap. To close this gap, we need to inflate enough so that the inside of the balloon is filled. A certain pressure will be formed, and the pressure will restore the automatic sealing nozzle to the original tight state, so that we can ensure that our inflated air will not leak from the automatic sealing.

Where to use aluminum balloons

Aluminum balloons are suitable for many occasions, especially as birthday party balloons, wedding occasions, can create a cheerful and peaceful atmosphere, making the guests feel happy. At the same time, it is also a good choice to give to your lover as a Valentine's Day gift. For example, a beautifully designed aluminum balloon with love expressions, plus flowers and chocolates, oh! I think your lover will happily accept it! You can even print a photo of the person you like on the surface of the balloon. Many stores abroad provide this service.

Will aluminum film letter balloons explode?

Whether an aluminum foil balloon will explode depends on what gas you are filling, for example, hydrogen will explode when it meets a fire. Air and helium will not explode. If you are asking, will the air leak because of being too big? After the aluminum foil balloon is too big, it may leak. Air will leak on the side of the letter balloon. Therefore, aluminum foil balloons are relatively safer, but the most important point is to choose a formal and guaranteed manufacturer.

What is aluminum balloon

Aluminum balloons (also called aluminum foil balloons, hydrogen balloons, and helium balloons in China, this is not accurate). It is precisely because some people call aluminum foil balloons because of their different understanding of aluminum film balloon materials, but the material we use here should be called aluminum film more appropriately; and the reason why some people call it hydrogen balloons and helium balloons is because The filling gas is different. When inflating aluminum balloons, hydrogen is generally used to inflate because of cost factors in China. Therefore, people in China generally call it hydrogen balloons, but the disadvantage of using hydrogen is that it is more dangerous. "Should we inflate the balloon with helium or hydrogen?" 》Here is a detailed introduction; and foreign countries generally use helium to inflate aluminum balloons, so foreign countries generally write helium balloon on the inquiry form.

The history of aluminum balloons

Aluminum balloons really began to be produced in the late 1970s. Before, because children were easy to burst when playing latex balloons, and the gas retention time was relatively short, people always wanted to develop a balloon that could keep the gas from leaking for a long time. A balloon that can bear the weight of a child. Finally found the material of aluminum film in the late 1970s. The surface printing of these produced aluminum film balloons not only looks very exquisite, but also produces a variety of aluminum film balloons of various sizes, such as dinosaurs, sea babies, giraffes, dolphins, monkeys, tigers, lions, etc. . Once the product came out, it was loved by people.
