Bubble wrap
Bubble wrap is a kind of packaging [1]or cover. it is used for protecting things that can be broken when moved or mailed. It is made of two very thin pieces of plastic glued together, with many small round air bubbles left inside. When these bubbles are squeezed and burst, they make a popping sound. many people find the sound soothing. it is sometimes used as a stress reliever. It was invented by accident in 1957 by Alfred Fielding.[2]
Composition
changeMost bubble wrap is made out of a plastic called Polyethylene. But when shipping delicate electronics and their components, a special plastic type of bubble wrap is used to remove static electricity, this way protecting delicate electronic chips.
The air bubbles, that protect easily broken items, can be found in many different sizes — from as small as 6 millimeters (1/4 inch) in diameter, to as large as 26 millimeters (1 inch) or more. It depends on the size of the thing being wrapped. Some larger objects may also need many covers of bubble wrap to be protected enough. Some mail envelopes contain bubble wrap inside.
