Our company is producing flexible packaging materials for food companies.
To try and get relevant feedback, a little more info might help, eg product category, eg -
3-ply corrugated cartons, inner Kraft cardboard boxes, styrofoam trays, plastic sheet, plastic cups, etc ??
Do you mean a Finished Product Specification Sheet ? (never heard of a Process Specification Sheet )
Or perhaps a Process Flow Chart in which case a hint as to the type of material again relevant.
