Some vertical form fill seal machines, like the SEPP, come with advanced features such as a continuous supply to film buffer and an impulse seal with film cutting blade. This helps to streamline the packaging process and reduce waste.
Here are some of the key features of a vertical form fill seal machine:
- PLC control and servo motor for easy operation
- Automatic bag forming, dosing, filling, sealing, coding, and conveying
- High-quality stainless steel construction for GMP compliance
- Horizontal and vertical temperature control for various materials
- Pocket diversification for different bag types
- Automatic alarming and protective functions for reduced wear and tear
- Double servo motors for accurate film drawing and faster speed
- Temperature independent control system with precision to ±1°C
How It Works
The vertical form fill sealing machine is a remarkable piece of equipment. It works by clamping the film roll on the shaft between two cones, which supplies film to the buffer, starting the process.
The forming shoulder converts the supplied film into a tubular shape, with the size determined by the size of the bags. This is crucial for ensuring the bags are the correct size for the products being filled.
The film is then transported over the filling pipe, where it will be sealed to form the bottom of the bag. The horizontal seam is sealed, and the closing seam of the previous bag is formed, with a knife cutting both bags apart.

During horizontal sealing, products are added to the bag via the filling pipe, making the process efficient and streamlined. This is especially important for high-volume production runs, where speed and accuracy are key.
The machine repeats the process when the batch is ready, forming the next bag and cutting it apart from the previous one. This continuous process allows for rapid production and minimal downtime.
