Functions of Packaging Machines

Packaging machines encompass a wide range, but their core functions typically include:

1. Metering and Filling

• Funcţie: Precisely measures product quantity/weight and fills it into containers.

• Aplicație: Counting pills, weighing food, volumetric filling of liquids into bags, bottles, cans.

2. Forming and Sealing

• Funcţie:

  • Forming: Shapes flat material (film, cardboard) into containers (bags, boxes).

  • Sealing: Reliably seals packages via heat sealing, crimping, capping, lidding, stapling.

• Aplicație: Making and sealing plastic bags, cartons, etc.

3. Labeling and Printing

• Funcţie:

  • Labeling: Automatically applies labels.

  • Printing: Prints date codes, batch numbers, barcodes directly on packaging.

• Aplicație: Ensures product identification, traceability, and compliance.

4. Wrapping and Bundling

• Funcţie: Wraps individual items or multi-packs with film or paper.

• Aplicație: Individual candy wrappers or multi-can bundles.

5. Cartoning and Case Packing

• Funcţie:

  • Cartoning: Loads products into cartons.

  • Case Packing: Packs multiple packages into shipping cases.

• Aplicație: Completes secondary and tertiary packaging.

6. Inspection and Rejection

• Funcţie: Integrates checkweighers, metal detectors, vision systems to auto-reject defects.

• Aplicație: Ensures package integrity, content accuracy, and safety.

7. Automation Integration and Handling

• Funcţie: Uses conveyors, robots for automatic conveying, positioning, and palletizing.

• Aplicație: Connects production stages into a complete automated line.

Summary: Packaging machines perform a series of standardized, automated operations. Their core function is to transform loose products into commercially viable, transport-ready packaged units, ensuring efficiency, safety, and traceability.
