12 oz / 340 g flat bottom coffee bag FAQ
What size is the 12 oz / 340 g flat bottom coffee bag?
GP-FB-340 uses W125 × H230 × D80 mm as a proposed sourcing size. D is the full bottom depth. Confirm the usable fill space below the pocket zipper; a nominal 12 oz designation is not a guarantee that every roast fits the same pouch.
Does the nominal capacity guarantee a fit?
No. Bean size, roast level, headspace, zipper placement and sealing layout affect usable capacity. Approve a filled sample with your actual coffee before ordering.
Which label size should I start with?
Start with 80 × 110 mm (GP-LBL-F-080110). This is a placement proposal, not a fit guarantee. Check folds, seams, valve position and the pocket zipper on the filled pouch before approving label artwork.
Are all three finishes in stock?
The three finishes are specification options, not a live stock listing. Request current availability, the nearest factory size, laminate structure, thickness, MOQ and a physical color sample.
Can I request a valve and custom printing?
Include the valve requirement, artwork count and quantities in the inquiry. Valve position, print method, setup charges, lead time and barrier performance must be confirmed for the selected construction.
