Paper / Kraft Bag Machines
Machines for producing multi-layer kraft paper valve sacks — the traditional choice for cement packaging with excellent printability and strength — 66 models in our database.
Kraft paper remains the global standard for premium cement packaging. Paper bag machines (primarily tubers and bottomers) are engineered to handle 2 to 4 plies of virgin or recycled kraft paper, creating rigid, breathable valve sacks. The porosity of the paper allows rapid air evacuation during high-speed filling, making it ideal for rotary packers.
💡 Buyer's Tip
When investing in paper bag machines, consider the paper quality available in your region. If using lower-grade recycled paper, you may need tuber machines with specialized tension controls to prevent web breaks. Also, consider integrated PE film unwinding for added moisture resistance.
