Bubble Wrap or air bubble packing is a transparent plastic packaging material that is mainly used to pack fragile or easily breakable items. The bubbles have regularly spaced protruding air-filled hemispheres which function as the cushioning agent for sensitive and easily breakable objects.

Bubble wrap is a transparent sheet made from polyethylene, or what is more commonly known as plastic. This plastic sheet contains air filled pods which resemble bubbles. The substance in the bubbles is air.

Perfect for packing fragile and breakable items, bubble wraps are made to intensively protect these valuable items. One face of the bubble wrap sheet is flat, while the other face is a layer of round air-filled bubbles. The bubbles are responsible for creating a cushioning that seizes the item from breaking.
