Bubble wrap
Description
Introduced in 1960 as a trademark of Sealed Air Corporation, Bubble Wrap was formed from a double layer of plastic film containing sealed bubbles, or air pockets, between the layers. The bubbles provide cushioning and are often used to provide some shock and vibration isolation Bubble wrap is typically made from Polyethylene films, but some brands may be composed of Polyvinylidene chloride or Polyvinyl chloride. The permeability of the film can result in deflation of the bubbles overtime. Some versions, such as Aircap@ [Sealed Air] and Polycap@ [Ipsind] have and additional layer of nylon that prolongs the lifetime of the bubble. Maximum cushioning is provided with the bubble side toward the object, however, direct contact with the film may leave marks and sharp edges may break bubbles. Some of the problems can be mitigated by placing two bubble layers face-to-face.
