Bubble Balloons are made of an amazing stretchy plastic material used for the outer balloon and a uniquely printed plastic material for the inner balloon. All Bubble Balloons are now packaged in a Moist-Pak. This improves the properties of the outer balloon material making it pop resistant to over inflation and outside pressures.
New Improved Bubble Balloons are Pop Resistant* and can be inflated using almost any regulator when they are packaged in a Moist-Pak! A Moist-Pak contains a wet towelette and allows moisture to permeate the plastic of the outer balloon. This moisture makes the outer balloon of a Bubble Balloon amazingly stretchy. In fact, the outer balloon is so stretchy, it is very difficult to pop due to over inflation. This outer balloon will keep on stretching and keep on stretching until you have put double the recommended helium inside of it. Even then, it may not pop! We recommend using 1.48cu.ft. of helium which is just when the wrinkles have COMPLETELY disappeared. It is the moisture in a Moist-Pak that makes the New Improved Bubble so amazingly POP-RESISTANT!
