How It Compares
| Traditional paper coffee filters | The drip coffee bag film retains more aroma and flavor, allows full expansion of grounds, and is compatible with automated bag-making machines |
|---|---|
| Glue-sealed filter films | The ultrasonic seal avoids chemical leaching and ensures a cleaner, safer brew, though it requires compatible sealing equipment |
| Plastic-based filter films | The non-woven film is compostable and environmentally safe, while plastic films are not and may fail eco-certifications |
Use Guide
- 1Unroll the film from the roll and feed it into the automatic drip coffee bag machine
- 2Ensure the machine is set to ultrasonic sealing mode for proper bonding
- 3Select the desired flavor compound if using a blended version
- 4Check seal integrity and film strength before starting a production run
- 5Clean the sealing heads regularly to prevent residue buildup
- 6Store unused film in a dry, cool place to prevent moisture damage
