We're looking to source premium flexible packaging for a 20 kg dry dog food project. The bag should have high-quality features, including a metallized high-barrier layer, resealable closure, and a gusset design. The quantity needed is 7,000 pcs, and we're interested in your insights on potentially adding a Nylon layer for enhanced strength. Can you provide a detailed quote that covers unit price for 7,000 pcs, MOQ, options with and without Nylon, printing costs, sample fees, production lead time, as well as EXW and FOB prices? Please also include export packing details. Happy to share reference photos if needed!
