This type of semi-automatic stretch wrapper uses a horizontal oriented ring to wrap stretch film around a product. The carriage of stretch film travels around the edge of the ring, applying stretch film as it moves. A semi-automatic horizontal ring stretch wrapper is commonly used to wrap long products. Some semi-automatic horizontal ring stretch wrappers require an operator to attach the first part of the film to the pallet or other object, then feed it into the ring, allowing it to be wrapped by the rotating carriages of film. Others only need the operator to feed the product through the ring.
