Explore our certified ODM manufacturing capabilities ranging from specialized single-serve coffee sachets to high-barrier commercial retail packaging.
Analyzing the global transition from traditional bulk roasted beans toward precision-portioned, high-barrier single-serve formats across commercial, industrial, and retail ecosystems.
The rapid global growth of specialized single-serve coffee formats—including ear-hang drip bags, instant micro-ground stick packs, and portioned nitrogen-flushed sachets—is propelled by evolving consumer preferences for boutique cafe-quality extraction without complex equipment. Global enterprise brands require reliable ODM (Original Design Manufacturer) partners capable of guaranteeing strict barrier integrity to protect delicate aromatics from atmospheric degradation.
Coffee roasted beans and fine grounds are exceptionally sensitive to ambient degradation. Volatile aromatics such as furans, pyrazines, and alkylpyrazines dissipate rapidly when exposed to oxygen. Furthermore, moisture ingress triggers stale flavor notes and lipid oxidation. Single-serve packet engineering solves this by creating micro-encapsulated controlled environments that lock in roasting metrics for 18 to 24 months.
For multinational coffee brand owners, hotel chains (HORECA), airline caterers, and private-label distributors, securing an established packaging supplier with robust production capabilities is paramount. ODM suppliers must balance high-speed flexible converting with customized film structures, high-definition gravure printing, and verified compliance with international food-contact standards.
An in-depth look at multi-layer barrier substrates, gas transmission control, and nitrogen gas flushing engineering for maximum shelf stability.
Modern single-serve coffee packet substrates are composite engineered structures engineered to withstand mechanical stress while presenting an impenetrable barrier against environmental agents. Common multi-layer matrix architectures include:
Packaging fine grounds requires active gaseous displacement. Ground coffee continuously releases carbon dioxide ($\text{CO}_2$) while absorbing free oxygen. During high-speed vertical form-fill-seal (VFFS) processes, ODM packaging films must support precision nitrogen ($\text{N}_2$) flushing.
Our engineered films maintain a tight sealing window that prevents micro-pinhole leaks, guaranteeing that internal residual oxygen levels remain below 0.5% throughout the product’s lifecycle, thereby halting lipid rancidity and preserving crema formation characteristics.

Introducing Jiangxi Nanchang Chengxin Packaging Co., Ltd. — A leading force in high-tech flexible packaging research, environmental stewardship, and advanced automated conversion.
Jiangxi Nanchang Chengxin Packaging Co., Ltd.
Founded on June 6, 1995, Jiangxi Nanchang Chengxin Packaging Co., Ltd. is located in Nanchang, Jiangxi Province. As a modern high-tech enterprise, the company specializes in flexible packaging manufacturing for sanitary products, food packaging, household tissue paper, and specialty high-barrier beverages.
Recognized as a "Jiangxi Private Science and Technology Enterprise" and a certified "Jiangxi High-tech Enterprise", Chengxin Packaging operates under rigorous international quality management systems including ISO9001 certification, Intellectual Property Management System compliance, and Credit AAA Enterprise status.
To deliver superior accuracy and fast turnaround for global ODM clients, our production facility is equipped with fully automated infrastructure:
Tailoring specific ODM packaging styles to meet consumer lifestyle demands and industrial filling line parameters.
Popularized across Asian and European specialty roasters, Japanese-style ear-hang drip bags feature non-woven Japanese filter paper enclosed within an outer high-barrier foil pouch. The outer pouch is flushed with nitrogen gas during packaging, ensuring that when opened, the consumer experiences freshly ground aromas identical to a barista pour-over experience.
Ideal for instant spray-dried, freeze-dried, or micro-ground specialty blends, slim fin-seal stick packs offer unmatched convenience for fast-paced consumers. Engineered with laser-scoring tear notches, these packets allow effortless opening while reducing outer material usage by up to 30% compared to traditional square sachets.
Designed for larger dose sizes (15g - 50g), these wide-format sachets accommodate high-density coarse grounds intended for cold immersion brewing. The outer packaging utilizes high-puncture-resistant co-extruded films to prevent accidental punctures during transit in commercial food service networks.
Navigating global regulatory landscapes including EU Packaging Waste Directives and plastic reduction commitments.
Traditional flexible packaging relies on combining incompatible plastics (e.g., PET bonded to PE), which renders the film unrecyclable in standard municipal recycling programs. Our ODM engineering team has developed high-barrier Monomaterial Polyethylene (PE/EVOH-PE) structures. By incorporating ultra-thin EVOH barrier technology into PE co-extrusions, the total PE content exceeds 95%, classifying the packet as fully recyclable under CEFLEX guidelines without compromising oxygen protection.
Utilizing plant-derived Polylactic Acid (PLA), Kraft paper, and certified cellulose barriers (NK/PLA), our industrial compostable coffee film series disintegrates into non-toxic organic biomass within 180 days under industrial composting conditions (EN 13432 compliant). This provides specialty coffee roasters with a compelling ESG narrative that resonates with environmentally conscious demographics.
A structured, phase-by-phase framework ensuring seamless conversion from original artwork design to global container delivery.
Analyzing bean oil content, ground size, target shelf-life, and filling machine specifications (VFFS speed, sealing bar temperatures).
High-definition intaglio cylinder engraving. Digital color matching via spectrophotometers ensuring 99% Brand Pantone fidelity.
Precision adhesive application using solvent-free compounding technology, eliminating VOC emissions and odorous solvent migration.
Full online photoelectric defect inspection, tensile seal strength testing, gas chromatography residual testing, and ocean/air export packaging.
Addressing key commercial, technical, and logistical questions from global buyers and packaging engineers.
Comprehensive packaging lines engineered for food, personal care, retail, and industrial export markets.
