Tubeline's Twin Wrap Kit holds two rolls of film and passes them through a single stretcher. This activates the wraps' bonding compound to form a strong 2-Ply layer of film that stands up to tough hay stalks and folds them over helping to prevent piercing of the wrap.
By combining two sets of two rolls for a total of four, Tubeline's twin wrap kit provides all the same protection as four separate stretchers with the additional benefit of producing a more durable bonded 2-Ply film that stands up better than four single ply layers.
