What is elastic twine?

While many elastic twines on the market are not suitable for cooking, Greenflex elastic twines are specifically tested for food contact and oven use under defined conditions. The string has no effect on the taste or color of the meat. The thread can withstand temperatures up to 240°C.
Our range of elastic twine was made to make life easier for you and your tying machine. Because of the conical shape, it suits perfectly into the most renowned twine tunnels. Our elastic cord is available in different sizes, strengths, colors and materials.

How to use elastic twine manually?

2. Cut a long piece of string and wrap it around the meat, tying it. To make a parallel loop, direct the string over the meat, hold it in place, and then guide the rest of the string under the meat.
3. Repeat until the entire piece of meat is knotted. Turn it over and knot the string around the back. Remove any unnecessary string.

The tunnel ensures that material flows continuously. To be thoroughly knotted, even long rolled roasts do not need to be rotated. The knotting after each tie enables for simple roll roast portioning without the thread falling free.
