about the air bubble film
Dec 25, 2017

Bubble film is most often formed from polyethylene (LDPE) film with a shaped side bonded to a flat side to form air bubbles. Some types of bubble wrap have a lower permeation barrier film to allow longer useful life and resistance to loss of air in vacuums.

The bubbles can be as small as 10 millimeters (2/5 inch) in diameter, to as large as 26 millimeters (1 inch) or more, to provide added levels of shock absorption during transit. The most common bubble size is 1 centimeter.In addition to the degree of protection available from the size of the air bubbles in the plastic, the plastic material itself can offer some forms of protection for the object in question. For example, when shipping sensitive electronic parts and components, a type of bubble wrap is used that employs an anti-static plastic that dissipates static charge, thereby protecting the sensitive electronic chips from static which can damage them.
