Engineered to perform in demanding processing and extraction environments, utilizing cutting-edge barrier films and sealing solutions.
A technical guide on high-performance materials, barrier configurations, and factory-scale automation for global brands.
Established in 1989, Dongfa Printing Co., Ltd. possesses over 35 years of professional manufacturing experience in printing and flexible packaging. Our operations are anchored in advanced manufacturing technology, utilizing a state-of-the-art GMP-certified clean workshop and high-speed rotogravure printing presses equipped with online quality inspection systems.
We specialize in engineering advanced co-extruded structures, liquid spout pouches, high-barrier roll films, and specialty lidding membranes. Crucially, our materials are formulated to withstand strict industrial sterilization protocols, including pasteurization and high-temperature retort steam sterilization, ensuring absolute package integrity across international distribution channels.
In the global premium coffee market, volatile organic compounds (aromatic compounds like thiols and furans) dictate sensory quality. Exposure to even trace amounts of oxygen causes rapid staling. Dongfa's high-barrier laminates are engineered to achieve an Oxygen Transmission Rate (OTR) of less than 0.1 cc/m²/24hr and a Water Vapor Transmission Rate (WVTR) below 0.1 g/m²/24hr, extending product freshness up to 18-24 months.
Coffee packaging requires complex multi-layer configurations. Our production team matches customized functional layers to achieve precise mechanical, thermal, and barrier properties:
Procurement agents in North America, Western Europe, and Japan look for three main factors when selecting suppliers: compatibility with filling machinery, raw material compliance, and high dimensional accuracy.
Our manufacturing processes ensure that all flexible materials are compatible with industrial filling lines (such as Bosch, Optima, and Ima). We monitor mechanical tolerances and friction levels (COF) to prevent feed faults. In addition, our manufacturing facilities adhere to strict food safety guidelines, supporting smooth customs clearance and regulatory compliance in destination markets.
Quality control is critical for flexible barrier food packaging. Dongfa Printing uses advanced inspection protocols to monitor physical properties from raw material to finished product:
Developing packaging solutions that balance food safety, durability, and processing efficiency.
We use EVOH and high-grade aluminum layers to block light, oxygen, and water vapor, protecting aroma and flavor compounds.
We are expanding our range of mono-material structures, such as PE/PE and PP/PP laminates, designed to improve recyclability without compromising product shelf life.
Our sealing layers are designed to seal cleanly at a wider temperature range, helping brands maintain throughput on automatic packaging lines.
Expert clarifications regarding technical parameters, material capabilities, and customization options.
For PP-based capsules, we recommend our NY+CPP or PET+VMPET+EVA easy-tear lidding films. These structures balance robust moisture barriers with clean, peelable seals, avoiding tearing or residue when the capsule is punctured or peeled.
We use high-barrier cores, such as VMPET or Aluminum Foil (AL), in our multi-layer structures. These materials block oxygen (OTR < 0.1 cc/m²/24hr) and moisture, keeping the volatile compounds in coffee fresh over long storage periods.
Yes. Our PET+AL+NY+RCPP laminated films are designed for retort sterilization. They can withstand temperatures up to 121°C–135°C under pressure, making them suitable for ready-to-drink coffee bases and liquid extracts.
We offer custom widths, roll diameters, and pouch dimensions. Our pre-press team matches roll specifications to your filling equipment. Minimum order quantities vary by film composition, and we support testing phases with pilot runs.
Yes. All raw materials (resins, adhesives, and inks) comply with FDA regulations for direct food contact. Our GMP cleanroom facilities are managed to prevent contamination throughout printing and lamination.
We provide superior packaging materials and reliable supply services to partners worldwide.
High-quality laminates, specialized packaging bags, and custom films designed for industrial automation lines.
