How to Design a Multi-Material Protective Pack RFQ from China
Sourcing guide to multi-material protective pack RFQs from China: carton, honeycomb, foam, edge board, and strap as one system with shared drawings, tests, and substitution rules.
Quick answer
Design a multi-material protective pack RFQ as one system: outer carton, separators/pads, foam or pulp inserts, edge board, and straps with shared drawings and tests. Quoting each line item separately without a pack-out map creates incompatible parts.
Issue one pack-out drawing
Show exploded components, materials, and assembly sequence. Number each part so honeycomb, foam, and carton suppliers quote the same revision.
Freeze interfaces
Define clearances between foam and honeycomb, carton ID vs insert OD, and strap paths over edge board. Interface errors cause crush or scuff even when each part “meets spec.”
Set system tests
Require drop/vibration/stack trials on the assembled pack, not only component datasheets. Assign who builds the trial pack.
Control substitutions
Ban silent swaps of cell size, foam density, flute, or edge-board thickness. Any change reopens system testing.
