Project Requirements
The U.S. project needed a white-kraft flat-bottom coffee bag for a 12oz, or approximately 340g, fill, with a side zipper, degassing valve and gravure artwork.
Packaging Approach
A 140-micron MATOPP / White Kraft / VMPET / PE laminate was converted into a 12.7 × 23.9 + 7.7 cm flat-bottom pouch with a side zipper and one-way valve.
Gravure Printing and Degassing Valve
The white-kraft laminate was gravure printed and then formed into the eight-side-seal flat-bottom shape. Side-zipper and valve installation completed the specified coffee bag configuration.
Project Result
The completed pouch is a 12oz white-kraft flat-bottom coffee bag measuring 12.7 × 23.9 + 7.7 cm. Its finished configuration combines gravure print, a side zipper and a degassing valve.
