Cardboard trays are filled with bottle/jars on the infeed platform of the machine, then a sheet of shrink-film is laid over the pack and tucked underneath.  A lever operates a hot wire to cut the film, then the pack is pushed onto the conveyer

The heat tunnel softens the plastic,which shrinks onto the pack as it cools on the outfeed conveyer.

Economical and easy to operate. Automatic machines are also available on request.
