Our solutions combine automated weighing with VFFS, sachet, and net bag packaging for a wide range of granules: snacks and nuts, rice and grains, sugar and salt, seeds and fertilizers, pet food, and more. Built with SUS304/SUS316 contact parts and IP65 protection, the lines integrate weighing, sealing, labeling, checkweighing, metal detection, X-ray inspection, case packing, and palletizing. This delivers stable high-speed output and fast changeovers. Typical outcomes include up to 30% capacity increase, up to 40% labor cost reduction, and up to 99.5% quality pass rate.
Applications and Product Behaviors
Snacks, Nuts, and Confectionery
High-speed multihead weighing provides consistent portions for mixed nuts, trail mixes, candies, and coated items. Algorithms balance precision and throughput while reducing breakage and oil carryover.
Rice, Grains, Sugar, and Salt
VFFS systems maintain seal integrity on fine or dusty products with product-effect compensation. Gusseted and block-bottom bags, plus nitrogen flushing, help preserve freshness.
Pet Food and Animal Feed
Rigid frames, IP65 enclosures, and wear-resistant parts suit oily and abrasive kibble and pellets. Inline checkweighers verify net weight across retail and bulk SKUs.
Seeds, Agriculture, and Fertilizers
Gentle handling reduces seed damage. Dust control and reinforced seals support storage stability, while accurate net weight and tamper-evident features aid compliance.
Machine Types and Bag Styles
VFFS Granule Packing Machines
Servo-driven film pull, automatic tension control, and synchronized dosing enable high-speed pillow, gusseted, and quad-seal bags. Options include nitrogen flushing, zipper applicators, euro-hole punching, and easy-open notches.
Typical Specs
Speed: up to 20–120 bags/min (dependent on product and bag)
Bag width: 60–250 mm; length: 60–350 mm; film width: up to 420/520/620 mm
Accuracy: typically ±0.3–1.0% with multihead or linear weighing
Seasoning and Sachet Granule Packaging
Compact automatic systems for single-serve salt, sugar, seasoning granules, and drink crystals. Supports flat, three-side, four-side, and stick packs with precise micro-dosing.
Typical Specs
Dose: 1–100 g; Speed: up to 60–180 sachets/min
Films: PET/AL/PE, OPP/CPP, and paper-based laminates
Net Bag Packaging for Granules
Ideal for produce and larger granules such as onions, citrus, potatoes, or nuts. Gentle filling and ventilated net bags support shelf life and transport.
Integrated Weighing, Inspection, and Conveying
Multihead and Linear Weighers
10/14/20-head multihead weighers deliver speed with memory buckets. 4-head linear weighers offer cost-effective accuracy for fragile or abrasive products.
Checkweighers, Metal Detectors, and X-Ray
Inline systems verify net weight and detect contaminants to meet retail standards. Reject stations ensure only conforming packs advance.
Snacks and nuts: +25–35% throughput with gentle handling and accurate mixes
Rice and grains: seal integrity under dusty conditions; rejects reduced by up to 50%
Pet food: stable weight control with integrated checkweighing; fewer complaints via contaminant control
