bubblewrap

Bubble wrap is a pliable sheet material consisting of two layers of plastic film that enclose a regular grid of air-filled bubbles. It is usually made from low-density polyethylene, with the bubbles formed by sealing air between the films. Bubble sizes vary, commonly ranging from about 6 millimeters to 12 millimeters in diameter, and sheet thicknesses differ accordingly. The result is a lightweight material that provides cushioning, moisture resistance, and flexibility for packaging.

Bubble wrap was invented in 1957 by Alfred Fielding and Marc Chavannes while attempting to create textured wallpaper. The concept did not succeed as wallpaper, but the inventors partnered with Sealed Air to commercialize the cushioning product. The term Bubble Wrap became a trademark in the 1960s and later entered common use to refer to this type of packaging material.

Uses of bubble wrap center on protecting fragile items during shipping and storage. It cushions by distributing impact energy, protects glass and electronics, and can serve as a moisture barrier. Some variants are anti-static to reduce electrical discharge for sensitive equipment. Reuse is possible in some cases, though repeated folding can degrade the bubbles. After use, it is typically disposed of as plastic film, with recycling dependent on local facilities.

Environmental and disposal considerations include its origin in fossil fuels and potential recycling challenges. Many communities accept LDPE film for recycling at designated drop-off sites rather than curbside programs, and some manufacturers offer recycled-content or biodegradable alternatives.

Variants and related products include air pillows, biodegradable films, and anti-static formulations designed for specific packaging needs.
