Drip Coffee Bag Packing Machine with Outer Envelope

Bring the café experience home. This machine automatically forms, fills, and seals Hanging Ear Drip Coffee Bags using Ultrasonic Technology. It then packs the filter bag into a gas-flushed Outer Envelope, locking in the aroma for a premium single-serve experience.

How to seal delicate filter paper without burning it?

Standard heat sealing destroys the non-woven fabric of drip coffee bags and can affect the coffee's taste. The LTC Drip Coffee Machine uses advanced Ultrasonic Sealing. This cold-welding technique creates a perfect, tasteless seal on the "hanging ears" without heat, ensuring the purest coffee flavor.

Features

  • Ultrasonic Sealing: Seals the inner filter bag instantly without heat, preventing breakage and burnt odors.

  • Inner + Outer Bag: Automatically packs the finished drip bag into a protective outer sachet in one continuous process.

  • Nitrogen Preservation: Flushes the outer envelope with Nitrogen to keep oxygen levels low and aroma high.

  • Volumetric Dosing: High-precision slide doser ensures every bag has the exact grams (e.g., 10g or 12g) for the perfect brew.

FAQs for Drip Coffee Packing

Q: Can I print the date on the outer bag?

A: Yes, the machine includes a ribbon code printer or can be fitted with a thermal transfer printer for dates and batch codes.

Q: Is Nitrogen flushing really necessary?

A: For drip coffee, yes. The ground coffee has a large surface area and oxidizes quickly. Nitrogen is essential to maintain a shelf life of 12+ months.
