Automatic Ice Cube Vertical Form Fill Seal Packaging Machine

Application:
The LD-420AS vertical packing machine combined with a single-head linear weigher is ideal for packing various free-flowing granular and cube-shaped products. It’s commonly used for food items like ice cubes, sugar, salt, nuts, and small snacks, as well as non-food granules such as detergent or chemical pellets.

Package Type:
This machine is designed for back sealing (pillow) pouches, offering clean and durable packaging for granular or cube-shaped products. It can also be adapted for gusset bags or flat pouches depending on product size and presentation needs.

Wide Application Range: 
The LD-420AS Vertical Packing Machine with a single-head linear weigher is designed for accurate and efficient weighing and packing of free-flowing granular and cube-shaped products. It features a compact design, stable operation, and precise sealing performance, making it ideal for medium-capacity production lines. The integrated system ensures smooth product feeding, accurate dosing, and clean bag sealing for long-lasting preservation.

This machine is widely used across multiple industries:

Food Industry: ice cubes, sugar cubes, salt, nuts, and small candies.

Frozen Products: mini ice blocks, frozen fruit cubes, and small seafood portions.

Chemical & Household Products: granular detergent, water softener pellets, and dehumidifier beads.

Workflow: 

1. Product Feeding: Ice cubes or other granules are lifted by the Z-type elevator and fed steadily into the single-head linear weigher.

2. Weighing: The linear weigher measures the product precisely according to the preset weight, ensuring consistency in every pack.

3. Bag Forming: The vertical machine automatically forms back sealing pouches from film rolls, preparing them for filling.

4. Filling: The measured ice cubes are accurately dropped into the formed bags without spillage or product damage.

5. Sealing and Cutting: Each bag is sealed tightly by heat sealing to ensure no leakage and then cut into individual finished packs.

6. Discharging: The finished pouches are conveyed out for collection, inspection, or secondary packaging.
