Bubble Wrap And Its Uses

By Dylan McThomas

Usually when transporting objects, particularly fragile ones, it is important to package them protectively. It is not uncommon for packages to be roughly handled, or accidentally dropped, and so cushioning the package is essential to minimise damage.

A good way of doing this is to use bubble wrap. Bubble wrap was a good way of protecting breakables from the hazards of transportation when it was created over fifty years ago, and still is today.

Bubble wrap itself is a transparent and plastic sheet with evenly spaced air bubbles protruding from it which when wrapped around a fragile item, provides cushioning for the item.

Two engineers by the names of Alfred Fielding and Marc Chavannes created bubble wrap in 1957. The term bubble wrap is technically a trademark of the Sealed Air Corporation (also created by Fielding and Chavannes) and in theory should only be used for that companys products.

The bubbles that make up the cushion will usually be available in a range of sizes for bigger and smaller items that need packing as different amounts of cushioning are required for each item. Multiple layers will usually be used on fragile objects, but for objects that arent likely to break, but have easily damageable/scratchable surfaces, a single layer would be enough.

The size of the bubbles in the sheet can vary, usually from around 6 millimetres to around 26 millimetres, but (depending on who you buy it from) you can usually ask for customized sizes.

Different materials are available for bubble wrap such as an anti-static plastic material for transporting fragile objects like sensitive electronic parts.

Bubble wrap is also used for amusement, as Im sure you well know if you cast your mind back to childhood. The bubbles make a clear popping noise when squeezed and pierced which is somehow satisfying. It is sometimes used as a stress relief tool and some websites even have virtual bubble wrap which you can pop by clicking on it. Some may call this pointless, others may call it brilliant, and the chances are that it has elements of both.
