A tight knot on a bag often just has to be cut off or torn off. This is not a problem when its contents are fully used. If you need to tie the bag back, you can undo the tightened knot using a simple method.
To do this, you need to take the bag by the knot so that it hangs, and begin to wrap it until the walls are twisted into a tube.
Then you need to hold the knot with your fingers from the sides and push a rigid tube through it.
After this everything will dissolve easily.
The method always works, unless, of course, the bag is tied as tightly as possible until the polyethylene stretches.
