Description
Product Video: Automatic Popcorn Weighing and Packaging
The Soonkpack SK-L420 High-Speed Popcorn Packaging Machine is an automatic vertical form-fill-seal (VFFS) packaging system designed for popcorn and other compatible snack products. It combines a high-speed vertical packaging machine, a 12-head multihead combination weigher, and an automatic feeding system to achieve continuous weighing and bag packaging.
In the video, popcorn is automatically conveyed to the 12-head combination weigher. The weighing system measures the product according to the preset target weight and releases it into the packaging machine. The SK-L420 then automatically forms bags from roll film, prints the production date, fills the popcorn, seals and cuts the bags, and outputs the finished packages.
This integrated popcorn packaging solution helps reduce manual weighing and filling, improve production efficiency, and maintain consistent package weights.
Watch the video to see the complete automatic popcorn packaging process, from feeding and weighing to finished bag output.
Complete Packaging Workflow:
Popcorn Feeding → Automatic Conveying → 12-Head Combination Weighing → Bag Forming → Date Printing → Popcorn Filling → Heat Sealing → Bag Cutting → Finished Bag Output
Key Features and Advantages of the SK-L420
Servo-Driven Dual Film Pulling System
The SK-L420 features a servo-driven dual film pulling system to ensure smooth and stable packaging film feeding. This helps maintain consistent bag forming, improve bag appearance, and support stable packaging operation.
Imported Brand Pneumatic Cylinders for Reliable Sealing
The machine uses imported-brand pneumatic cylinders to provide stable sealing pressure. This helps achieve secure seals and clear sealing patterns, reducing the risk of bag leakage and minimizing defective packages when the machine is properly adjusted.
Multilingual Touchscreen Control System
The control system supports multiple language options, making operation more convenient for users in different countries and regions. Available language configurations can be confirmed according to customer requirements.
External Film Roll Mounting Structure
The external film roll mounting structure makes packaging film replacement more convenient. Operators can replace film rolls more easily, helping simplify routine operation and reduce film-changing downtime.
Fully Automatic Packaging Process
When integrated with the automatic feeding system and 12-head multihead combination weigher, the SK-L420 automatically completes product feeding, weighing, bag forming, date printing, filling, sealing, cutting, and finished bag discharge.
This integrated process reduces repetitive manual work and helps improve overall packaging efficiency.
12-Head Multihead Combination Weigher
The 12-head combination weigher selects suitable combinations of individual weights to reach the preset target. This supports efficient weighing and helps maintain consistent package weights when correctly configured for the product and target weight.
High-Speed Vertical Packaging
The SK-L420 has a specified packaging speed range of 5–80 bags per minute. Actual production speed depends on the target packing weight, product characteristics, bag dimensions, packaging film, and operating conditions.
Flexible Packaging Dimensions
The machine supports bag widths of 80–200 mm and bag lengths of 80–300 mm. These dimensions allow different package sizes to be configured according to product volume and packaging requirements.
Integrated Packaging Solution
By combining the vertical packaging machine, 12-head combination weigher, and automatic feeding system, the SK-L420 provides an integrated solution for snack manufacturers seeking to automate weighing and bag packaging.

Suitable Applications
The SK-L420 automatic weighing and packaging machine is designed primarily for popcorn and can also be evaluated for other compatible snack products.
Popcorn
- Butter popcorn
- Caramel popcorn
- Sweet popcorn
- Other suitable popcorn varieties
Other Snack Products
- Potato chips
- Puffed snacks
- French fries snacks
- Peanuts and other nuts
- Sunflower seeds and pumpkin seeds
- Candy and compatible confectionery products
The suitability of each product depends on its shape, density, fragility, flow characteristics, target packing weight, and required production speed. Product testing may be necessary for fragile, irregular, or lightweight materials.
Packaging Bag Types and Film Options
The SK-L420 is a vertical form-fill-seal packaging machine that forms bags from roll film. Pillow bags with a back seal are a common option for popcorn and snack products.
Pillow Bag / Back-Seal Bag
The packaging film is formed into a tube and sealed along the back. The machine then fills the product and seals the top and bottom to produce individual bags.
This bag style is widely used for popcorn, puffed snacks, nuts, seeds, and other compatible products.

Q2. Can the SK-L420 popcorn packaging machine use weighing systems other than a 12-head multihead weigher?
Yes. The SK-L420 can be configured with different dosing systems according to your product characteristics, target package weight, accuracy requirements, and budget.
Available options may include:
- Measuring Cup Rotary Dosing System: A cost-effective option for suitable granular products. Its weighing accuracy is generally lower than that of a properly configured multihead weigher.
- 10-Head Multihead Weigher: Suitable for applications requiring a different weighing configuration.
- 12-Head Multihead Weigher: A common option for automatic snack weighing and packaging.
- 14-Head Multihead Weigher: An alternative for applications with specific weighing and production requirements.
The appropriate system depends on the product, target weight, required accuracy, and production speed.
Q3. Can the popcorn packaging machine fill bags with nitrogen?
Yes. A nitrogen flushing system can be added as an optional configuration. Nitrogen flushing can help reduce the oxygen level inside the package and support product freshness, depending on the product, packaging film, and sealing performance.
Please inform us of your nitrogen flushing requirements when requesting a quotation so we can evaluate the appropriate configuration.
Q4. Can the machine produce connected bags or individual bags?
Yes. The required output format can be discussed before ordering. Depending on the selected configuration, the machine can be arranged for individual bags or connected bags.
