The new two-ply laminated structure is made of a base material of 26-pt GPI Pearlkote and an internal layer of 16-pt GPI Omnikote. GPI prints the box flats in six colors via a sheet-fed offset printing process.
Winery spokesman Joel Tefft notes, “We chose GPI as our box material supplier because they had a solution to our bulging problem.” He explains the difficulty was “caused by the liquid going to the lowest level and pushing out the sides of the box. The direction of the corrugation made the [previous] box weaker. The new box’s Z-Flute helps counteract wine bulge. The box also has improved compression strength to provide better stacking strength during product storage and distribution. And the material is cost-effective. We are saving approximately 40 percent compared to the cost of the old box materials.”
