EQUIPMENT OVERVIEW
Product details & configuration
High Speed Granule Packaging Machine
Our High Speed Granule Packaging Machine is designed for automatic weighing, filling, bag forming, sealing and cutting of granular products such as nuts, seeds, snacks and grains. As a professional packaging machinery manufacturer, LANTUPACK provides high-speed VFFS packaging solutions to improve production efficiency and meet different packaging requirements.
The Automatic High-Speed Vertical Granule Packaging Machine (LT-420S to LT-720S Series) is an industrial-grade, high-efficiency automation assistant designed to solve vertical bagging pain points such as slow packaging speeds, material entrapment in seals, uneven film pulling, and high film waste.
High Speed Granule Packaging Machine Features
Our High Speed Granule Packaging Machine is designed for efficient and reliable packaging of granular products. It supports automatic weighing, bag forming, filling and sealing, helping food manufacturers improve packaging efficiency and maintain consistent packaging quality.
LANTU Machinery introduces core models including the LT-420S / 520S Series (Standard Servo Film-Pulling System) and the LT-620S / 720S Series (Flagship Dual/Triple Servo Heavy-Duty Wide-Bag Units). Featuring high-precision servo film drives, pneumatic/servo horizontal sealing mechanisms, and dynamic anti-jamming technology, paired with bag formers and high-efficiency chain-cut/hole-punching units, the equipment acts like a precise and fast bag-shaping guardian. Whether handling small-to-medium delicate granules like nuts, puffed foods, candies, and oatmeal (e.g., 10g–1000g pillow bags/gusseted bags) or large-capacity heavy vertical bags like animal feeds, plastic pellets, pesticide granules, and detergent beads (e.g., 1kg–5kg large stand-up bags/quad-seal bags), it achieves automated bag forming, ultra-fast filling, flat sealing, and cutting in one seamless operation—ensuring zero material entrapment and excellent package aesthetics.
As an original manufacturer of packaging machinery, LANTU Machinery has simplified the complex fully automatic vertical process—film unwinding, bag forming, synchronized filling, sealing, and coding—into an operation as simple as using a smartphone. Operators simply set the bag length and temperature on the PLC touchscreen, load the film roll, and the machine automatically performs photoelectric tracking, film pulling, bag forming, synchronized discharging with combination weighers or auger fillers, and smooth output of finished bags. With bag widths ranging from 60mm to 350mm, paired with dedicated 10-head/14-head combination weighers or volumetric cup fillers, this series significantly shortens packaging workflows while saving labor, time, and costs.
Choosing a reputable source manufacturer is crucial for your return on investment. LANTU Machinery’s proven servo film-pulling and temperature-controlled sealing technologies, combined with robust reliability and industry-leading film utilization, ensure smooth, zero-breakdown operation on your vertical packaging lines.

Key Factors to Consider When Purchasing a Vertical Granule Packaging Machine
To help you choose the best machine for your production line, consider the following key selection criteria:
Target Bag Dimensions and Maximum Film Width:
Bag Width 60mm–200mm: Select LT-420S;
Bag Width 80mm–250mm: Select LT-520S;
Bag Width 150mm–300mm: Select LT-620S;
Bag Width 200mm–350mm (Large heavy bags): Select LT-720S.
Material Physical Properties & Feeding Integration:
Irregular bulk items / multi-head combination: Pair with 10-head/14-head combination weighers;
Uniform free-flowing granules: Pair with volumetric cup fillers;
Fragile granules: Require cushioned inclined formers and anti-breakage chutes.
Film Material & Thickness: Composite films (OPP/CPP, PET/PE) use standard heated sealing jaws; single-layer PE film requires a dedicated PE film impulse sealing system.
Target Capacity (BPM): Choose single-servo or dual/triple-servo configurations based on speed requirements (e.g., 30–90 bags/min).
Special Functional Modules: Nitrogen gas flushing, date coding (ribbon/inkjet/laser), gusset forming, or Euro hole punching.

Frequently Asked Questions (FAQ)
Q1: How do I choose between LT-420S/520S and LT-620S/720S?
A: Selection depends primarily on target bag width and package weight. For small-to-medium packages under 1kg (film width within 520mm), select the LT-420S/520S. For large 1kg–5kg heavy granule bags (film width up to 720mm), choose the LT-620S/720S flagship heavy-duty unit.
Q2: Can the machine handle single-layer PE film?
A: Standard models are optimized for laminated films. If using eco-friendly single-layer PE film, simply specify our optional PE impulse sealing jaws and pulse control module when ordering.
Q3: How difficult is adjustment when changing bag sizes or film rolls?
A: Extremely simple. Replace the bag former with the corresponding size (quick-release structure) and adjust the bag length and speed on the PLC touchscreen. Complete specification changes take less than 10 minutes.
