How bubble wrap cushions an impact
Bubble wrap cushions an object by letting sealed air pockets compress when a force arrives. That deformation can spread the contact and give the object more distance over which to slow down. The bubbles do not make impact energy disappear; the packaging changes how the force reaches the protected surface.

A softer route to stopping
An object striking a hard surface stops over a short distance. Cushioning introduces material that can deform, allowing more movement during the stopping process and potentially reducing peak forces.
Bubble wrap provides this deformation through flexible plastic pockets containing air. The pockets compress and the film changes shape under load. Some energy can be dissipated through deformation, while some can be stored and returned.
Protection depends on the available cushioning distance. If the bubbles are already flattened, they have little remaining space to compress.
- Intact pockets provide deformable spacing.
- Multiple contact points help distribute load.
- Excessive force can flatten or rupture the bubbles.
The object's weight, shape, wrapping thickness and outer box all affect the result. A thin layer cannot protect every object against every drop.
