The SH45 automatic shrink wrapping machine is a combined machine which, using a single work station, performs the hooding and heat-shrinking operations of the product to be packaged. The SH45 automatic machine uses a reel of shrink film in tubular form equipped with side bellows. In the different versions, up to three film reels can be reached. The film is heat-shrunk on the product by means of a gas-fired ring oven; all functions are controlled by a PLC that manages the automatic and manual operations.
