The company is displaying its latest version of the system at the Chicago show, which combines an L-bar sealer and shrink tunnel system.
This allows for packing, sealing and shrinking products in a centrefold shrink-wrap film, which according to the group, requires minimum maintenance.
The DEM 450 series can be used for a wide range of products thanks to its precise temperature and speed controls, and it also features 24-hour operation.
Tomasz Borys, marketing associate at Packaging Aids Corp, another of Pac Machinery Group's sister companies, said the print market still accounts for the majority of shrink packaging sales.
He said: "Although most are high speed today, there is still a need for the smaller and semi-automatic L-bar sealers for packaging."
Pac Machinery Group's sister companies also include Clamco, Vertrod and Converting Technology.
