What is a kraft paper packaging bag?
A kraft paper packaging bag uses kraft paper as the outer layer, laminated with inner plastic layers for sealing and barrier protection. It provides a natural, artisanal appearance for coffee, snacks, tea and dry food packaging.
Is kraft paper alone enough for food packaging?

What inner structures are used with kraft paper?
Common inner layers include Kraft/PE for basic moisture protection, Kraft/VMPET/PE for improved barrier, and Kraft/AL/PE for higher barrier requirements such as coffee packaging.
Can kraft paper bags include zippers or valves?
Yes, zipper and degassing valve options can be reviewed according to the bag design. Placement should be confirmed during the design stage.
