Abstract

A laminated packaging material for fabrication into a container for a flowable food product is disclosed herein. The laminated packaging material has a fluted medium between a first layer and second layer. The fluted medium may have a flute density of 200 to 450 flutes per linear foot. The fluted medium may also have a flute height profile of 8 mils to 50 mils. The laminated packaging material may be fabricated into a gabletop carton or a parallelepiped container such as the TETRA BRIK.RTM. container. The laminated packaging material may have a barrier layer such as aluminum or another gas impermeable composition. The laminated packaging material provides substantial material savings due to the fluted medium.
