Õhumullikile

Õhumullikile, often referred to as bubble wrap, is a transparent plastic material used for packaging fragile items. It consists of a thin layer of polyethylene film, enclosing small pockets of air. These air-filled pockets act as cushioning, absorbing shock and protecting goods during transit or storage. The invention of õhumullikile is credited to Alfred Fielding and Marc Chavannes, who initially conceived it in 1957 as a textured wallpaper. Its potential as a protective packaging material was recognized later, leading to its widespread commercialization.

The manufacturing process involves extruding molten polyethylene into a thin sheet, which is then passed through a roller system that creates the characteristic air bubbles. The film is then sealed to trap the air within these pockets.Õhumullikile is available in various bubble sizes, from small to large, offering different levels of protection. It can also be found in antistatic varieties, which are crucial for protecting electronic components from electrostatic discharge.

Beyond its primary use in packaging, õhumullikile has found applications in other areas. Some people use it for insulation in greenhouses or windows due to its air-trapping properties. It's also sometimes used in craft projects or as a plaything for children. While effective, concerns about its environmental impact exist due to its plastic composition. Recycling options are becoming more available, though proper disposal remains important.
