In late 2024, a major U.S.-based fast-casual food-service chain awarded Dongguan Xingkaihua a multi-year contract for custom greaseproof paper bags featuring full-color branding. The bags, produced using fluorine-free formulations and food-grade safe inks, deliver excellent oil resistance and shelf-stable quality. Recognizing the company's capacity to manage low MOQ and fast turnaround, the chain integrated them into national supply for bakery, snack, and takeaway packaging. The contract reflects confidence in the company’s production consistency, quality control (including color, thickness, and grease resistance testing), and export logistics. It marked a significant milestone, further validating its reputation in North American food packaging supply.
