Smoothing board's rough spots

On the paperboard side, converters emphasize their energies are primarily devoted to banishing board thickness issues, ensuring consistent converted results, and squeezing more mileage out of uncoated board stocks.

According to Marketing Manager Pat McGee, Graphic Packaging leaps the thickness barrier with Composipac, a patented process in which the company reverse-prints on film, vacuum metallizes behind the inks, and then laminates the film to paperboard. Lamination eliminates board thickness issues, and has led to successful replacement of preprinted corrugated material. Composipac allows less expensive base material to be used, while still achieving superior graphics. The process can also integrate more packaging functionality, such as moisture and vapor barriers.
