Bubble Wrap
Bubble wrap, also known as air-cushion film,air bubble film,air bubble sheet, generally is low-density polyethylene as the raw material,and is currently widely used as a shockproof and cushion packaging material.
The bubbles that provide the cushioning for fragile or sensitive objects are generally available in different sizes, depending on the size of the object being packed, as well as the level of cushioning protection that is needed.
The bubbles can be as small as 6 millimeters (1/4 inch) in diameter, to as large as 26 millimeters (1 inch) or more, to provide added levels of shock absorption during transit.
