Why Is Small-Format Liquid Packaging Becoming More Important?
Single-use and small-format liquid packaging has become an important option for manufacturers that need convenient portion control, easier transportation, and controlled product consumption. Sachets can be used for condiments, sauces, personal care products, liquid detergents, samples, and other products where a compact package is commercially practical.
However, liquid products create packaging challenges that dry products do not. A small amount of liquid remaining inside a sealing area can affect seal integrity, while differences in viscosity can influence filling accuracy and production stability. For this reason, a suitable vertical form-fill-seal system needs coordinated control of film movement, filling, sealing, and cutting.
For manufacturers seeking a compact automated solution, the High Speed Automatic Liquid VFFS Machine for Max Bag Length 150mm is designed around these requirements. Its maximum 150mm bag length makes it especially suitable for small sachet formats rather than large liquid bags.
What Is a High Speed Automatic Liquid VFFS Machine for Max Bag Length 150mm?
A vertical form-fill-seal machine creates finished bags from rollstock film within one automated production sequence. The film is formed into a tube, the product is dosed into the package, and the sealing system closes the package before cutting the finished sachet.
The High Speed Automatic Liquid VFFS Machine for Max Bag Length 150mm is specifically configured for liquid and paste products. According to its product specifications, it supports a bag width of 40–100mm, a bag length of 50–150mm, and packaging quantities from 5–100ml. It can also support three-side and four-side sealing formats.
The machine is designed for products such as soy sauce, cooking oil, vinegar, seasoning pastes, shampoos, liquid soap, and similar liquid or viscous materials. This makes it relevant to food, personal care, household, and other consumer-product packaging applications.
How Does the Machine Work?
The packaging process follows a continuous vertical workflow. Understanding this sequence helps buyers evaluate whether the machine matches their production requirements.
- Film feeding: Packaging film is unwound and transported through the forming section.
- Bag forming: The film is shaped into the required package configuration.
- Liquid filling: A suitable pump system dispenses the predetermined quantity of liquid or paste.
- Sealing: The packaging material is sealed according to the selected package format.
- Cutting: The finished sachet is separated from the continuous film structure.
- Discharge: Finished packages leave the machine for subsequent collection, inspection, or secondary packaging.
Because these stages are integrated into one automated process, manufacturers can reduce repetitive manual packaging operations and achieve more consistent production cycles.
Why Does Four-Servo Control Matter?
One of the defining characteristics of this machine is its four-servo configuration. Independent servo control is used for longitudinal sealing, heat sealing, cold sealing, and cutting operations.
This configuration is important because liquid packaging requires accurate synchronization. If film feeding, sealing, filling, and cutting are poorly coordinated, manufacturers may experience inconsistent bag dimensions, weak seals, material waste, or package leakage.
The centralized PLC control system and touchscreen interface allow operators to adjust operating parameters and monitor production conditions. A fault-tracking alarm system can also help identify abnormal operating conditions more quickly.
- More precise synchronization between major packaging movements
- Convenient parameter adjustment through the touchscreen interface
- Better control of sealing and cutting operations
- Improved adaptability to different film materials
- More straightforward troubleshooting through machine alarms
What Are the Key Technical Specifications?
