Automatic Sachet Filling and Sealing Machine

I. Sachet Filling Sealing Machine: Packaging Solution for Small Bags

The automatic sachet filling and sealing machine has become an indispensable filling equipment for small bag packaging in food and other industries. With the features of high degree of automation, flexible adaptability, and stable reliability, it perfectly integrates bag making, metering, filling, sealing, and coding processes. Read information below, you will know more about such filling machine.

II. What Functions the Sachet Filling Machine Have

The automatic sachet filling and sealing machine has comprehensive and efficient functions. From bag forming to final bag coding, the sachet filling sealing machine can all do.

Automatic Bag Forming Function: The equipment automatically pulls packaging material from the roll film, precisely positions it using photoelectric sensors, and instantly forms a three-dimensional packaging bag.

Automatic Metering Function: Based on the characteristics of the material, a high-precision metering system ensures accurate weight or volume for each bag.

Automatic Filling Function: After metering, the material is smoothly and residue-free filled into the formed bag.

Automatic Sealing Function: Using heat sealing technology, the bag opening is firmly and aesthetically sealed, effectively protecting the product from moisture, leakage, and extending its shelf life.

Coding Function: Key information such as production date, batch number, and expiration date are clearly printed on the surface of the packaging bag, complying with national regulations and facilitating traceability.

III. How about the Components of the Filling Machine

The collaborative work of multiple precision components contributes to the high efficient sachet bag filling and sealing performance.

Metering Section: This is the heart of packaging precision. We offer specialized solutions for materials with different physical properties.

1)For Powder Materials (e.g., milk powder, seasoning powder): The machine employs servo motor-driven screw metering, ensuring high precision for Powder Materials (e.g., milk powder, seasoning powder).

2)For Granular Materials(e.g., sugar, salt, tea leaves): Commonly use measuring cups or vibratory feeders for metering; simple structure, fast speed, suitable for regular granules.

3)For Liquid/Sauce Materials (e.g., tomato sauce, chili sauce, honey): Optional piston pumps, peristaltic pumps, or magnetic pumps for metering; peristaltic pumps are particularly suitable for liquids with high hygiene requirements.

Film Stretching and Bag Making Section: This part consists of a film stretching machine (traction mechanism) and a forming unit. The flat roll of film is cleverly folded into a bag shape by a unique forming device. Then the film stretch machine pulls down step by step, preparing for subsequent filling and sealing.

Cut Section: After sealing, the finished bags need to be separated. Depending on the material and requirements, the equipment can be equipped with straight cutters, serrated cutters, or easy-tear cutters. These cutters ensure clean cuts without burrs, improving the overall quality of the product.

Coding Section: Usually installed on the horizontal or vertical sealer, it uses thermal printing technology to clearly imprint the text onto the packaging bag at the moment of sealing. The coding information is durable.

IV. What Speed Models You can Choose

To adapt to production needs of varying scales, we offer a diverse range of sachet filling machine configurations from low speed to High Speed.

Single-lane machine(low speed): There is only one lane of filling sealing structure. The speed is about 20-60BPM for the small bag filling sealing.

Double-lane machine(medium speed): With two lanes of automatic filling sealing cutting functional parts, the filling machine speed is higher. The rough range is about 40-90BPM.

Multi-lane machine(high speed): Featuring more parallel workstations, the small bag filling sealing speed can reach over 300BPM. It is very suitable for the large scale food factories for the food bag packaging use.

V. Can You Use the Sachet Filling Sealing Machine in Food Industry

Yes, the sachet filling and sealing machines are particularly widely used in the food industry:

Powdered and Granular Foods: Pepper powder, chili powder, chicken essence, mixed spice powder, coffee powder, soy milk powder, lotus root powder, milk tea powder, solid beverages, sugar, salt, oatmeal, etc.

Liquid and Sauce Foods: Soy sauce, vinegar, cooking wine, fruit juice, concentrated fruit pulp, ketchup, salad dressing, chili oil, hot pot sesame oil, yeast liquid, cheese sauce, etc.

VI. Why Choose Such Type Filling Equipment

The automatic sachet filling and sealing machine has the advantages of modular precision structure, diverse model configurations, and wide material adaptability. Such sachet filling machine provides enterprises with a one-stop, high-efficiency, low-loss intelligent packaging solution. You can use the device as a powerful assistant in enhancing product competitiveness and moving towards Industry 4.0.
