Japanese Material Drip Coffee Filter Bags – Single Serve Hanging Ear Pour Over Filters

The Hanging Ear Coffee Filter Bags is engineered for coffee lovers seeking a clean, high-quality manual brewing experience without the need for traditional equipment. Made from premium Japanese non-woven filter paper, these bags deliver exceptional filtration, ensuring smooth water flow while retaining fine particles for a pure, aromatic cup.

Each filter bag features a reinforced hanging-ear design, allowing it to securely attach to most mugs and cups. The Japanese material is known for its durability, heat resistance, and superior extraction performance, making it the top choice for specialty coffee roasters and global brands. The clean “Open Here” tear line offers convenience and ensures the consumer can easily prepare the bag for brewing.

These drip coffee filter bags are heat sealed for added strength, making them suitable for filling, nitrogen flushing, and use inside flat pouches, foil sachets, or retail gift boxes. Whether you are producing coffee for retail shelves, online subscription boxes, hotel amenities, or personalized coffee kits, this product supports a variety of packaging formats.

Widely adopted in Japan, Korea, Southeast Asia, and the Middle East, the Japanese material drip filter bag aligns with global demands for portable, single-serve brewing. It is ideal for outdoor enthusiasts, office workers, hotel guests, airline passengers, and any consumer who values convenience without compromising taste.

By combining premium Japanese material with modern hanging-ear design, this filter bag provides a consistent, professional-level pour-over experience anytime and anywhere.

Key Features

• Stable bracket ears: Die‑cut and pre‑folded for quick setup; fits most mugs and tumblers.
• Clean taste, consistent flow: Food‑grade filter media with controlled pore size, low fiber shedding, and strong wet strength.
• Ready to fill and seal: Supplied top‑open; two or three side seals configured per your filling process.
• Custom branding on ears: 1–3 color print on bracket panels for logos, brew icons, or instructions.
• Reliable in use: Tear‑notch and reinforced seams minimize failures during bloom and pour.

Materials and Options

• Filter media (heat‑sealable):
  • PP nonwoven (typical 18–25 gsm): neutral taste, strong wet strength, very consistent flow.
  • Wet‑strength paper (approx. 32–40 gsm): classic paper mouthfeel; confirm sealability and flow rate for your roast profile.
  • PLA/bio‑nonwoven: specialty sustainable option; verify heat resistance and taste transfer for hot water.
• Bracket/ears:
  • PET or PET‑laminated paper with food‑grade adhesive/seal layer; die‑cut hooks for secure grip.
  • Printing on ear panels: spot colors (Pantone), small vector logos, simple icons; matte or gloss.

• Coffee fill weight: 7–12 g standard; 14–16 g high‑dose option.
• Pouch body (filter area): typically 90–100 mm wide × 70–80 mm tall.
• Ear span when opened: approx. 85–105 mm to fit cup rim diameters ~70–95 mm.
• Seal widths: 3–4 mm standard; reinforced bottom seam for high‑dose.

Brew Performance
