Compared to FIBCs, Multi-wall paper bags often require more attention to detail to run smoothly including product, equipment, and environment. Since large raw material producers utilize automated, high-throughput filling machines, each package must be designed to meet the specific criteria. Key design elements include:

• Raw material characteristics: Bulk density, particle size, flow characteristics, sensitivity to moisture, etc.
• Sizing for the right weight of filled product
• Sizing for filling machine specifics – fill spout, spout offset, sealing type, etc.
• Palletization – desired final pallet weight, pallet sizing.
• Shipping – Mode of transport required, distance to destination, time in transit, handling of packages, etc.
• Storage Requirements – How long will the product be in the package
