Here we would like to introduce the structure, working principle, feature and technical data, etc of the back-sealing dressings and sauces packaging machine. Hope that it can help you understand this highly efficient packaging equipment suitable for viscous sauces.
It is a fully automatic dressings and sauces packaging equipment specifically designed for large-capacity soft bag packaging. It uses a roll film bag making and back-sealing method to package salad dressing, mayonnaise, cheese sauce, red bean paste, mung bean paste, and sweet chili sauce into bags. The packaging weight is mainly from 500g to 6kg, meeting both household consumption needs and catering channel applications.
How about the structure and working principle of this type packaging machine? You can kindly read the following explanation.

Following is the working video of the machine:
The key features of this equipment lie in its utilization of a rotor pump as the dosing system, as well as its film-pulling and bag-making system.
For viscous sauces such as salad dressing, mayonnaise, and red bean paste, ordinary metering pumps cannot deliver them stably. This equipment uses a rotary pump as the metering pump, offering the following advantages:
Advantages | Description |
High viscosity adaptability | Handles sauces with viscosity up to 50,000 cP |
Pulsation free delivery | Smooth filling, no splashing |
Particle Capacity | Handle sauces containing fine particles |
Strong Self-Aspiration Capacity | Draw material directly from the lower-level hopper |
Functions | Description |
Servo film pulling | Precisely controls bag length, accuracy ±1mm |
Automatic deviation correction | Ensure accurate sealing position |
Tension control | Maintain film surface flatness, reducing wrinkles |
Quick film change | Convenient roll film replacement, reducing downtime |
