A vertical packaging machine is an automated packaging system that forms bags from a continuous roll of flexible film, fills the product, seals the package, and cuts the finished bag.
Unlike a premade pouch packing machine, which uses bags manufactured in advance, a vertical packaging machine creates the bag during the packaging process. This makes vertical packaging particularly suitable for sachets, stick packs, small-format bags, and multi-lane production.
It can be configured for powders, granules, liquids, sauces, pastes, and small solid products. Depending on the application, All-Bloom multi-lane models can reach up to 80 cycles/min, with lane configurations and bag sizes selected according to the product and packaging requirements.
How Does a Vertical Packaging Machine Work?
The basic process is:
Roll Film → Film Feeding → Bag Forming → Product Filling → Sealing → Cutting → Finished Bag
1. Film Feeding
The machine unwinds a continuous roll of packaging film and controls its position as it moves through the machine. Film selection depends on the product, sealing requirements, barrier performance, and final bag structure.
2. Bag Forming
The film is shaped into the required bag format by forming and sealing components. Depending on the application, the machine can produce formats such as: Back-seal bags /Stick packs, 3-side seal sachets, 4-side seal sachets, Special-shaped sachets,Pillow bag, Gusseted bag, block bottom, or other customized format.
3. Product Filling
A suitable filling system measures and dispenses the product into the formed bag. The filling system is selected according to product characteristics rather than using one universal dosing method.
- Powder:Auger filler
- Granules:Volumetric cup or multi-head weigher
- Liquid:Liquid pump
- Sauce and paste:Piston or customized pump
- Small solids:Counting system
4. Sealing and Cutting
After filling, the package is sealed and separated into individual bags. Cutting can be configured according to the required appearance, including straight, zigzag, round, or customized cutting.
What Products Can a Vertical Packaging Machine Pack?
A vertical packaging machine can be configured for a wide range of products. The appropriate filling system depends on factors such as product flowability, particle size, density, viscosity, filling weight, and production speed.
Product Category | Typical Products | Filling System | All-Bloom Example |
Powder | Protein powder, milk powder, coffee, spices, nutritional powder | Auger | |
Granules | Sugar, salt, tea, seeds, seasonings | Volumetric / weighing | |
Liquid、Sauce & Paste | Energy drinks, mouthwash, shampoo, liquid detergent,Ketchup, sauces, jelly, cream, hair mask | Piston Pump/ Gear Pump/Rotary Pump/Perostaltic Pump/ Ceraic Pump | |
Small Solids | Candy, tablets, pills, capsules | Counting system |
Actual machine configuration depends on product characteristics, filling volume, bag size, material, and required output.
What Types of Bags Can a Vertical Packaging Machine Produce?
Depending on machine configuration, film material, and sealing requirements, vertical packaging machines can produce different package formats, including:
- Back-seal bags
- Stick packs
- Three-side seal sachets
- Four-side seal sachets
- Shaped sachets
- Straight-cut bags
- Zigzag-cut bags
- Round-corner and customized-cut bags
What Are the Key Advantages?
A vertical packaging machine is a practical choice when manufacturers need:
- High-volume production — selected models reach up to 80 cycles/min
- Multi-lane packaging — configurations can be customized for higher output
- Flexible bag sizes — selected models support different bag widths and lengths
- Multiple filling systems — suitable for powder, granule, liquid, paste, and counting applications
- Roll-film packaging — bags are formed during the packaging process
- Line integration — printing, inspection, conveying, and other auxiliary equipment can be added
For powder applications, for example, the GH600BS-F uses servo-driven auger filling, with the manufacturer’s specification stating an error rate of ≤3% under the specified configuration.
Quick Decision
Choose vertical packaging when your priority is high-output sachet, stick-pack, or roll-film packaging. If you need stand-up, zipper, or spouted finished pouches, an automatic premade pouch packing machine may be a better option.
