What every comparable factory quote must include
Same specification line
Ask each plant to repeat paper GSM, bag style, handle, window film and decoration process on one line. If a plant substitutes 80 g/m² for 120 g/m² or changes a twisted handle to a die-cut, treat that as a new construction, not a silent equivalent. Burst strength and drop-test methods, when requested, should name the method rather than a marketing adjective. A grocery SOS blank and a printed shopping bag cannot share that line.
Costs outside the piece price
Print plates or screens, handle attaching, artwork revisions, inner cartons, pallets and freight stay outside the piece or carton price unless the reply lists them. A lower piece figure that hides tooling is not a cheaper total. This desk does not publish a savings percentage because the price comparison file on this site is empty.
Sample and document path
State whether you need a stock blank, a decorated sample or a line-trial quantity. Request food-contact and migration testing files for the named paper, ink and coating pairing. Those documents belong to the supplier lot. They are not converted into a site-wide certification badge. Drawings follow after first contact; this form has no upload field.
Digital print versus flexographic printing or offset is a run-length trade-off, not a quality slogan. High SKU counts and frequent logo changes can reduce plate cost with digital print; a frozen long run often keeps unit cost and spot-color control better in flexo. A die line for a logo panel should travel with the bag drawing so print buyers can quote colors on the same silhouette.
Limitations stay explicit: this desk does not promise US contract filling, does not hold inventory, and does not treat a supplier preference (high-end, mid-range, budget or undecided) as a verified rating. Read the RFQ checklist, then continue to inquiry options.
