XfilPak offers three types of vertical form fill&seal bagger.
1) Low-speed
The VFFS-800 and VFFS-1400, fall into this category. They are capable of handling pillow, gusseted, and doy-style stand-up bags, as well as hole punches. These models are equipped with servo drives for both the pull belts and sealing jaw.
2) High-speed Continues Motion
This high-speed CM-1000 machine is a suitable choice for applications that require fast speeds. The reason this machine falls into the continuous motion category is that the film does not have to stop to obtain its vertical seal. The vertical sealing bars are continuously moving, enabling uninterrupted sealing.
3) Tubing fill and seal machine
the TFS-1100, falls into this category. This machine utilizes tubular film material made from PE (polyethylene) to produce bags of various sizes, eliminating the need for a former. This results in reduced complexity and faster, more efficient production. The machine is user-friendly and can be easily adjusted to create bags of different sizes, making it suitable for a wide range of packaging applications
All models include a widescreen easy-to-use HMI that makes working with the machine comfortable.
The working principle and diagram of vertical form fill seal machine is as follows:
The initial step, which is a mechanical process, involves forming the package from a film roll. To accomplish this, the machine and devices guide the film onto a conical tube called the forming tube. This shapes the film into the desired bag form and seals the bottom and side seams at both ends of the film. The width of the package is determined by the layout of the forming tube, while the machine controls the length. Switching to a different package width is easy for an operator as they can simply replace the forming tube.
There are several types of seals, but the most commonly used are lap seals and fin seals. In a lap seal, the back of the top side overlaps with the front of the bottom side and is sealed. In a fin seal, the forming tube brings the film’s sides together, sealing the inner edges. Lap seals require less film as they correspond to the width of the seal on each bag. However, some films have special barrier layers (such as for odor or heat resistance) that require a fin seal for proper sealing. Films can also be equipped with additional features like zippers or gas release valves to preserve the freshness of the packaged products.
Our vertical packaging machines are designed with a focus on reliability and easy maintenance, offering a range of standout features. Here are some compelling reasons why you should consider choosing our machine for your packaging needs:
Firstly, our machines incorporate two servo motors, enhancing accuracy and ensuring reliable performance.
Additionally, easy accessibility to the electrical box and internal components simplifies maintenance tasks, enabling you to keep the machine in optimal working condition effortlessly.
Our PLC temperature controls provide precise temperature regulation, surpassing previous standards and ensuring superior control during the packaging process.
With one servo motor dedicated to horizontal sealing and another for pulling down the bag, the resulting seals are robust and long-lasting.
The presence of a 10-inch high-quality Omron human-machine interface (HMI) and PLC offers peace of mind. You can monitor the machine’s operations, ensuring it operates efficiently and flawlessly.
In summary, XFilPak’s vertical form-fill-seal machines guarantee exceptional quality and performance, making them an ideal choice for those who prioritize top-tier packaging equipment.
