Description

[Sealed Air] 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 The name is now a generic term given to a range of cellular cushioning sheets made of low-density Polyethylene films. Some brands also have a Polyvinylidene chloride or Polyvinyl chloride film coating. The permeability of the film can result in deflation of the bubbles overtime. Some versions have and additional layer of nylon that prolongs the lifetime of the bubble.

Avoid direct contact between bubble wrap and objects. Bubbles facing out are more prone to breakage, but bubbles faced toward the object can leave distinctive bubble pattern surface marks (especially if no interleaving layer is used). Bubbles tend to break in areas where protection is most required, such as corners and projections. Some of the problems can be mitigated by placing two bubble layers face-to-face, bubble side in.

Applications

Short term, soft packing material often used on paintings or in conjunction with tissue for 3D objects:

  • Packing and cushioning material with interleaving material (i.e. tissue, cardboard, poly film); can be applied only to corners or entire object
  • Helpful in shock protection for short-term shipping cycles
  • Transport, such as in field kits

Personal Risks

Sealed Air Bubble Wrap®: SDS

Collection Risks

  • Not for use in long-term-storage
  • Bubbles should be used face-out, away from object or in double layers with bubbles facing in
  • Avoid direct contact with object
  • Bubble pattern may transfer and become imprinted on objects if left in direct contact or held taut against the surface for long periods of time
  • Bubbles may deflate over time
  • Poly(vinylidene chloride) and Poly(vinyl chloride) films may release hydrochloric acid
  • Tissue will not prevent the migration of acid.

Working Properties

Comes on large rolls. Available with perforation to tear sheets.
