Our Sterile Liquid Pouch Forming Machine is designed for efficient, large-scale production of aseptic liquid packaging mainly used in the food and other fluid-based industries. Compatible with all heat-sealing materials, including pure PE, it supports the creation of high-integrity pouches designed to maintain strict hygiene standards.
With a film width capacity of 2400mm and a roll diameter of up to 1200mm, the machine accommodates wide-format materials for uninterrupted, high-yield operations. It forms pouches with a maximum width of 2400mm and up to 1300mm in length per double, offering extensive versatility for various packaging formats and volumes.
The machine is built on a reinforced industrial body measuring 46000mm × 8300mm × 3400mm, with a total weight of 36 tons, providing the structural stability needed for high-speed, continuous production.
Operating across four synchronized production lines, it delivers a steady output of 17 bags per minute per lane, meeting high-capacity demands while ensuring clean, precise, and durable sealing. Whether used in food-grade or sterile environments, this machine provides reliable performance and maximum production efficiency.
How does this machine maintain such a high level of cleanliness throughout the forming process? Let’s take a closer look at the key features and processes.
To prevent outside air, dust, or particles from entering the forming zone, these machines are built with sealed enclosures. The entire forming process—from film unwinding to pouch sealing—takes place in a protected environment that keeps airborne contaminants out.
Most sterile pouch machines are equipped with HEPA filters (High Efficiency Particulate Air). These filters continuously purify the incoming air inside the chamber, removing over 99.97% of particles down to 0.3 microns. This is essential for keeping microorganisms and dust from settling on the pouch material.
Before the film enters the forming area, it often passes through a UV sterilization tunnel or a chemical mist chamber. This ensures the outer surface of the packaging material is disinfected before it is shaped into a pouch.
Modern sterile pouch forming machines minimize human contact with the pouch during the process. Automation and robotic handling systems are used to reduce manual intervention, which is a common source of contamination.
Inside the forming chamber, positive pressure airflow helps to push out any airborne particles and prevent contaminants from entering. This constant stream of clean air helps maintain a microbially controlled environment.
Many machines are equipped with CIP/SIP systems that allow internal cleaning and sterilization without disassembly. These systems use hot water, steam, or chemical solutions to flush and sterilize internal surfaces, maintaining hygiene between production runs.
The sealing parts of the machine operate at controlled high temperatures, which not only form the pouch but also create a sterile barrier by killing any residual microbes during the sealing process.
All components that come in contact with the film or liquid—such as rollers, nozzles, or cutting tools—are made of food-grade stainless steel and are designed for easy cleaning and sterilization.
By combining physical barriers, air filtration, sterilization steps, and automation, a sterile pouch forming machine ensures that each pouch is formed in a contamination-free environment.
