The Meypack shrink wrappers of the SW Series are available as both single roll and also as double roll shrink wrappers.

Machine types of the SW Series that utilise the single roll technology are distinguishable by the absence of a sealing beam and have only one seal because the products are only wrapped by one roll of film. This is a distinct advantage when printed film is being used, not only because of the bottom seal but also because the printed film can be precisely centred. These machines can be operated at a speed of up to 100 cycles per minute. Two and three lane systems are also possible.
