Product Introduction

The PBF-250 Automatic Auger Powder VFFS Packing Machine is designed for automatic packaging of small quantities of dry powder into sachets. The machine integrates film feeding, bag forming, auger dosing, powder filling, heat sealing and bag cutting into one continuous packaging process.

It is particularly suitable for coffee powder, instant drink powder and other fine powders that require controlled dosing and compact sachet packaging. The auger dispenses powder according to preset screw revolutions, while the VFFS section forms and seals each package automatically.

Why Use Auger Filling for Powder Products?

Fine powder does not always flow consistently under gravity. Depending on particle size, density and moisture content, powder may bridge, generate dust or discharge unevenly. An auger controls material movement through screw rotation, making it suitable for small-dose powder packaging.

01

Powder Bulk Density

The weight of the powder per unit volume.

02

Particle Size

How fine or coarse the powder particles are.

03

Flow Characteristics

How easily the powder flows through the auger.

04

Moisture Content

How much moisture the powder contains.

05

Auger Diameter

The size of the screw that moves the powder.

06

Auger Speed

How fast the screw rotates during filling.

07

Target Filling Weight

The weight each sachet should contain.

Suitable Products

Designed for small-dose powder packaging applications. Final machine configuration should be selected according to the powder's bulk density, particle size, flowability, moisture content and target filling weight.

Key Features

01

Auger Screw Filling System

The auger screw controls powder dispensing. The filling quantity is determined by the preset number of auger rotations, providing controlled dosing for small-volume powder packaging. The outer filling tube works closely with the auger and helps reduce powder leakage during filling.

02

Automatic VFFS Packaging

Bag forming, powder filling, sealing and cutting are completed automatically from roll film. This integrated process reduces manual packaging work and provides continuous production.

03

Touchscreen Control Panel

The machine is equipped with a touchscreen interface for easier operation and parameter adjustment. Compared with conventional switches and buttons, the touchscreen provides a more intuitive operating interface, and it can be customized according to production requirements.

04

Photoelectric Color-Mark Sensor

A photoelectric sensor detects registration marks on printed packaging film. This allows the machine to position printed graphics more accurately before sealing and cutting, helping maintain a consistent finished package appearance.

05

Adjustable Sealing Temperature

The sealing temperature can be adjusted through the control system according to different heat-sealable film materials. This helps maintain stable sealing quality when changing packaging films.

06

Multiple Sealing Styles

The standard machine uses back-side sealing. According to packaging requirements, the machine can also be customized for three-side or four-side sealing, providing greater flexibility for different sachet designs.

07

Compact Machine Structure

With a footprint of approximately 600 × 760 mm, the PBF-250 combines dosing and VFFS packaging functions in a relatively compact design, suitable for production areas where space efficiency is important.

Working Principle

Packaging film is automatically pulled through the bag-forming section and shaped into a sachet. The auger filling system measures the powder according to a preset number of screw rotations and discharges it into the formed bag.

After filling, the machine automatically completes heat sealing and cutting. For printed packaging film, a photoelectric sensor detects the registration mark and helps maintain the correct position of the printed design.

How It Works

Film feeding, bag forming, auger dosing, powder filling, heat sealing and bag cutting — one continuous packaging process.

01

Film Feeding

Packaging film is automatically pulled through the bag-forming section.

02

Bag Forming

The film is shaped into a sachet.

03

Auger Dosing

The auger measures the powder according to preset screw rotations.

04

Powder Filling

The measured powder is discharged into the formed bag.

05

Heat Sealing

The machine automatically heat-seals the filled sachet.

06

Bag Cutting

Each sealed sachet is cut to size.

07

Finished Sachet Output

The finished sachet leaves the machine.

Bag Forming & Heat Sealing

Packaging film is automatically pulled through the bag-forming section and shaped into a sachet. The machine is designed for compatible heat-sealable packaging films, typically PP- and PET-based materials.

The sealing temperature can be adjusted through the control system according to different heat-sealable film materials, helping maintain stable sealing quality when changing packaging films. Printed roll film can be used together with the photoelectric registration sensor.

Heat Sealing & Cutting

After filling, the machine automatically completes heat sealing and cutting. The vertical sealing system and horizontal sealing and cutting unit work together to close each sachet.

The standard machine uses back-side sealing. According to packaging requirements, the machine can also be customized for three-side or four-side sealing.

Touchscreen Control & Registration

The machine is equipped with a touchscreen interface for easier machine operation and parameter adjustment. Production parameters can be adjusted through the touchscreen when changing products or bag sizes.

A photoelectric sensor detects registration marks on printed packaging film, allowing the machine to position printed graphics more accurately before sealing and cutting.

How much powder each sachet contains.

02

Powder Characteristics

Density, particle size and flowability of the powder.

03

Bag Dimensions

The length and width of each sachet.

04

Sealing Style

Back seal, three-side or four-side seal.
