Key Benefits
- Produces inner and outer bags simultaneously, cutting packaging time by half compared to sequential machines
- Volumetric cup filling delivers consistent 5 to 15 g per bag with minimal giveaway across a batch
- Ultrasonic sealing avoids heat damage to coffee aroma and prevents film scorching on sensitive films
- Stepper motor controls outer bag sealing for accurate, repeatable bag length and stable positioning
- SUS304 stainless steel parts in food contact zones meet food safety standards and resist corrosion
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation in the bag
Application Scenarios
- Coffee roasters packaging small-batch specialty blends for direct-to-consumer or retail sale
- Contract packers handling multiple coffee brands with quick changeover between bag sizes and film types
- Roasters upgrading from manual filling to automated inner and outer bag sealing for improved consistency
- Producers using compostable or biodegradable films who need a machine that handles sensitive materials
Who It Is For
- Coffee roasters who need to pack granule or powder coffee in inner and outer bags with consistent weight
- Contract packers serving multiple coffee brands with short runs and frequent format changes
- Producers using PLA, paper, or aluminum composite films who require a machine with food-safe materials
- Buyers replacing a manual or outdated machine that cannot handle dual-layer bagging efficiently
Problems It Solves
- Manual inner and outer bagging takes too long and leads to inconsistent fill weight and seal quality
- Heat sealing damages delicate coffee aroma and can melt thin films like PLA or paper-based composites
- Inconsistent bag length from poor positioning leads to misaligned labels or wasted film
- Lack of nitrogen flushing shortens shelf life for oxygen-sensitive coffee blends
- Outdated machines cannot handle multiple film types including biodegradable or aluminum laminates
Technical Features
- Volumetric cup filling system for 5 to 15 g per bag with consistent output
- Ultrasonic sealing for both inner and outer bags with no heat or adhesive required
- Stepper motor controls outer bag sealing for accurate and stable bag length positioning
- PID temperature controller for precise heat control during sealing process
- PLC control system with human-machine interface for easy operation and settings
- All food contact parts made of SUS304 stainless steel for hygiene and durability
- Optional flat cut, date printer, easy tear device, and nitrogen flush connector
- High-spec components including imported cylinders for stable and accurate performance

How It Compares
| Manual inner and outer bagging | The C19D replaces a hand-filling team and ensures consistent weight and seal quality, but requires a fixed 1200 x 900 mm footprint and trained operator |
|---|---|
| Heat-sealed dual-layer machine | Ultrasonic sealing avoids film scorching on sensitive films like PLA and paper, but requires an air supply and precise setup |
| Single-layer bag machine | The C19D produces inner and outer bags together for better protection and shelf life, but uses more film and requires more setup time |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz outlet with 3.7 kW capacity
- 2Load the film roll matched to your chosen inner and outer bag size and film type
- 3Set the volumetric cup to the desired fill weight between 5 and 15 g
- 4Adjust the stepper motor for accurate outer bag length and position
- 5Run ten sample bags and check fill weight, seal quality, and bag length before batch start
- 6Clean the volumetric cup and sealing heads between different coffee types to avoid aroma carry-over
