__NOTOC__ Bubble wrap is a pliable transparent plastic material commonly used for packing fragile items. Regularly spaced, protruding air-filled hemispheres (bubbles) provide cushioning for fragile items. "Bubble wrap" is a generic trademark owned by Sealed Air Corporation. In 1957 two inventors named Alfred Fielding and Marc Chavannes were attempting to create a three-dimensional plastic wallpaper. Although the idea was a failure, they found that what they did make could be used as packing material. Sealed Air Corp. was co-founded by Alfred Fielding in 1960.〔(【引用サイトリンク】 url=http://www.packagingknowledge.com/bubble_film_bags.asp )〕 The term is used generically for similar products, such as bubble pack,〔The term "bubble pack" can also refer to a blister pack〕 bubble paper,〔(【引用サイトリンク】title= bubble pack )〕 air bubble packing, bubble wrapping or aeroplast; Sealed Air denotes its product as a brand of "cushioning material".〔(【引用サイトリンク】 title=Proper use of Sealed Air Corporation Trademarks )〕 ==Design== The bubbles that provide the cushioning for fragile or sensitive objects are generally available in different sizes, depending on the size of the object being packed, as well as the level of cushioning protection that is needed. Multiple layers might be needed to provide shock and vibration isolation. A single layer might be used just as a surface protective layer. Bubble wrap is used to form some types of mailing envelopes. Bubble wrap 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 6 millimeters (1/4 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 1centimeter. 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. The bubbles can be shaped in many ways, even heart-shaped, as the Italian company Torninova Corporation did in 1997. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Bubble wrap」の詳細全文を読む スポンサード リンク
