Described are stretchable and formable lighter than air balloons including a high barrier lamination. The stretchable and formable balloons stretch when overinflated instead of failing. The balloons are formed from a lamination including a polyester film with a total thickness of 4 &#x3bc;m to 12 &#x3bc;m including a biaxially oriented polyester core layer and at least one amorphous copolyester skin layer. The polyester film has an Elongation % in the transverse direction (TD) or machine direction (MD) of greater than 125%.

Stretchable and formable lighter than air balloons made from a biaxially oriented polyester film

A long life balloon formed from a lamination. The lamination includes a polyester film with a total thickness of 4 &#x3bc;m to 12 &#x3bc;m. The polyester film includes a biaxially oriented polyester core layer and at least one amorphous copolyester skin layer. The lamination also includes a sealant layer and a gas barrier layer on an opposite side of the polyester film from the sealant layer. The oxygen transmission rate of the balloon is less than 0.1 cc/100 sqin/day, a bonding strength of the gas barrier layer to the surface of the polyester film is more than 300 g/in at dry conditions, a sealing strength of the balloon is more than 3.5 kg/in, and a floating time of the balloon is more than 20 days.

Lighter than air balloon made from a biaxially oriented polyester film

The present invention relates to articles and methods for producing non-latex balloons with low surface electrical conductivities and an extended product life. In a preferred embodiment, a multilayer composite film having an exposed metallized layer is coated with an elastomeric sealant layer that increases electrical resistivity of the balloon product to greater than 1.0Ohms/sq. The invention relates to articles and methods for producing needed bonds and seal strength required to manufacture non latex balloons. The balloons of this invention have an extended product life because they are more resistant to common defects like pin holing and stress cracks than conventional balloon systems.
