Introduction
The WPV450 Vertical Packaging Machine from Weeshine is designed for automatic packaging of large-weight granular products ranging from 1kg to 10kg. With stable performance, flexible bag sizing, and efficient automation, the WPV450 is widely used in food, agriculture, pet food, and chemical industries.
Equipped with a maximum film width of 930mm and a packaging speed of 20–30 bags per minute, this vertical form fill seal (VFFS) machine provides an ideal solution for manufacturers seeking reliable high-volume packaging for heavy-duty applications.
Designed for Large Bag Packaging Applications
Large bag packaging requires higher machine stability, stronger sealing performance, and precise weighing accuracy. The WPV450 vertical packaging machine is engineered specifically to meet these production requirements.
The machine supports packaging weights from:
- 1kg rice bags
- 2kg frozen food bags
- 5kg pet food bags
- 10kg nuts or grains packaging
Its heavy-duty structure ensures stable operation even during continuous long-hour production.
Suitable for Various Granular Products
The WPV450 is suitable for packaging a wide range of granular and bulk products, including:
- Rice
- Beans
- Sugar
- Salt
- Seeds
- Coffee beans
- Nuts
- Candy
- Frozen vegetables
- Pet food
- Fertilizer granules
- Plastic pellets
The machine can be integrated with multihead weighers, volumetric cup fillers, or linear weighers depending on the product characteristics.
Key Features of the WPV450 Vertical Packaging Machine
1. Large Film Width Capacity
The WPV450 supports a maximum film width of 930mm, allowing production of larger bag sizes for heavy products. This makes it ideal for bulk packaging applications.
2. Stable Packaging Speed
With an operating speed of 20–30 bags per minute, the machine balances speed and accuracy for medium and large-sized packaging.
3. Accurate Weighing System
When combined with a multihead weigher or linear weigher, the WPV450 achieves high weighing precision, reducing product giveaway and improving production efficiency.
4. Strong and Reliable Sealing
Heavy bags require durable seals during transportation and storage. The WPV450 uses stable temperature control and strong sealing systems to ensure reliable package integrity.
5. User-Friendly Touch Screen Control
The PLC control system with touchscreen interface allows operators to easily adjust parameters such as bag length, sealing temperature, and production speed.
Flexible Packaging Styles
The WPV450 can produce different bag types according to customer requirements, including:
- Pillow bags
- Gusset bags
- Quad seal bags
- Punch hole bags
Optional functions include:
- Nitrogen flushing
- Date coding
- Metal detection
- Check weighing
- Finished bag conveyor
Advantages of Automated Large Bag Packaging
Using an automatic vertical packaging machine offers significant benefits compared with manual packaging operations:
Improved Production Efficiency
Automatic bag forming, filling, sealing, and cutting reduce labor costs and increase output consistency.
Reduced Product Waste
Accurate weighing systems help minimize overfilling and material loss.
Better Packaging Appearance
Uniform bag shapes improve shelf presentation and brand image.
Lower Operating Costs
Automation reduces dependence on manual labor while improving long-term production stability.
