Thermoforming may traditionally be associated with plastics, but paper-based packaging was the central attraction on the Reiser stand, where the Variovac thermoformer was shown running cellulose-coated paperboard.
“We are able to run this at 12 cycles a minute, which is a comparable speed to an amorphous polyethylene terephthalate/polyethylene (APET/PE) laminate base film,” says packaging specialist Mike Carrington. “Customers have all the benefits of a roll-stock machine, without needing to use premade trays.”
The trays are home-compostable, but the board content limits the depth they can be pressed down to. As Reiser explains, with a larger overall tray area, the forming process can go deeper.
