All customised balloon are done using vinyl stickers, hence it's normal for bubbles to form, sticker starts to wrinkle and eventually fall when balloon start to shrink.
Foil / Mylar Balloon are more sensitive to temperature change. It will shrink when there is a sudden change in temperature, e.g. When you bring the foil / mylar balloon from outdoor (26~ 30°C) to air conditioned area (18~22°C). You can either use a straw or pump to blow some air into the balloon to make it look fuller. Usually this small amount of air does not affect the overall floating. Bringing the balloon to outdoor may also work as the higher temperature will expand the helium gas inside the balloon.
Likewise, when there is a sudden change of temperature from low (26~ 30°C) to high (31~ 35°C), helium gas in the balloon will expand and sometime cause it to burst.
A fully inflated foil / mylar balloon should have wrinkle at the side of the balloon. If the balloon has less or no wrinkle, it means that the balloon has been over inflated and may burst easily.
Helium balloon floating time may vary based on temperature, environment, and handling. Longevity is not guaranteed for any balloon taken outside due to the higher temperatures, strong wind and rain. at higher temperatures the gas expands and becomes less dense which can lead to an over-inflated balloon that is likely to burst. To ensure your balloons last as long as possible you should store them in cool temperatures and away from direct sunlight or heat sources where possible. At lower temperatures, helium gas contracts and becomes more dense, causing the balloon to deflate.
|Type of balloon||Approximate Floating time (indoor)|

|24" Bubble Balloon||1 - 2 days|
|24" Latex Balloon||1 - 2 days|
|36" Latex Balloon||1 - 3 days|
|36" Confetti Balloon||10 to 12 hours|
|Jumbo Gender Reveal||6 to 8 hours|
|Air-filled Balloons||Does not float|
When latex balloons are exposed to air, heat, and sunlight, they can also become stained or cloudy. This is caused by oxidation of the latex material used in most balloons. Oxidation occurs when oxygen molecules interact with the molecules in the latex material and cause it to break down over time. Additionally, dirt particles in the air can cause oxidation which leads to staining or cloudiness over time. Those whom prefer a matte look will love the new shades.
