A "France Royal Drip Coffee Packaging Machine with Outer Envelope" refers to a specialized, often fully automatic, industrial machine that creates individual, single-serve drip coffee bags (like hanging ear coffee) and then seals each inside a larger, protective outer pouch, ensuring freshness, often using nitrogen flushing and features like date printing. These machines handle inner bag formation, coffee filling, sealing (often ultrasonic or heat seal), and outer bag sealing, all in one integrated process, suitable for various granular products.
