How Do I Keep Mylar Balloons From Deflating?
To keep Mylar balloons from deflating, make sure you inflate them properly and tie them tightly. Avoid over-inflating or under-inflating them as that affects their longevity. Keep them away from sharp objects and direct sunlight as it may cause them to burst or damage the surface. Additionally, try not to expose them to extreme temperatures as that also affects their durability. Finally, consider using a high-quality sealant or balloon sealing machine to further ensure that the helium stays trapped inside.
