A twist tie is a fastener made of one or more metal wires encased in a thin strip of paper or plastic, in such a way that it can bend and retain its shape. It is used to tie the openings of containers including bags, such as garbage bags or bread bags. It is also called garden twist wire. A twist tie is used by wrapping it around the item to be fastened, then twisting the ends together. They are often included with boxes of plastic food bags or trash bags, and are commonly available individually in pre-cut lengths, on large spools, or in perforated sheets called gangs.
The outer covering can be in a variety of colors with or without printing. Plain paper, metallic paper, plastic, poly, or custom coatings are popular for different applications. The plastic, poly, or metallic paper twist ties withstand water better than the uncoated paper versions. Different sizes and strengths are used for different applications, from a small closure for a bag of bread to a large, heavy tie to hold unwieldy garden hoses in place. A twist tie with a broad paper covering may also be used for labeling.
They were invented by Charles E. Burford in 1961.
