The Engineering Behind PressureBall: 16-Ply Composite Technology
Designed to handle the pressure... for months!
Most tennis ball containers are simple plastic. PressureBall is an engineered 16-layer composite matrix designed to do one thing: hold internal pressure indefinitely against the laws of physics.
To achieve this, we moved away from standard plastics and utilized industrial-grade co-extrusion technology. Here is the breakdown of the science inside the tube.
The 16-Ply Architecture
PressureBall is constructed from three distinct sections that are heat-sealed to create a permanent, flexible pressure chamber.
Outer Composite (7-Ply): The first line of defense against the elements and physical wear.
Core Section (2-Ply): Two layers of Printed Polyester that provide structural tension and UV protection.
Inner Composite (7-Ply): The final barrier that maintains the internal “micro-climate” for your tennis balls.
The Gas Barrier: EVOH Technology
This is the heart of the system is the EVOH (Ethylene Vinyl Alcohol) layer.
While standard plastics are porous at a microscopic level (allowing air to leak out over time), EVOH is the global “gold standard” for gas containment.
It is an ultra-thin, high-barrier resin that acts as an invisible wall, preventing air molecules from escaping the tube even under high pressure.
Structural Integrity: Polyamide & LLDPE
To make the tube “court-proof,” we integrated materials typically used in heavy industrial packaging:
Tear-Resistant Nylon (Polyamide): Three layers of high-tensile Polyamide provide the “skeleton” of the tube, ensuring it can be dropped, stuffed into a gear bag, or sat on without bursting or stretching.
Hermetic Seal (LLDPE): The Linear Low-Density Polyethylene layers allow for a perfect heat-welded seal. This ensures the tube is 100% airtight at the seams, where most other pressurized containers fail.
