Packaging operations vary by scale and product type. The "three ways of packaging" typically refer to manual, semi-automatic, and automatic methods used in manufacturing, e-commerce fulfilment, and export packing lines.
1. Manual packaging
Manual packing is performed by human operators. It's flexible, requires low capital investment, and works well for small batches, custom orders, and highly delicate products that need individual attention.
2. Semi-automatic packaging
Semi-automatic lines combine machines with human operators. Common in medium-scale operations: a tray former or filler handles repetitive steps while humans load/unload or perform inspection.
3. Automatic packaging
Fully automated systems are ideal for high-volume manufacturers and exporters. Conveyors, robotic pick-and-place, thermoform-fill-seal lines, and automated case packers reduce labor and increase speed.
Choosing the right method
Decide based on product fragility (use ESD-safe trays for electronics), order volume, capital availability, and sustainability goals (rPET trays vs corrugated boxes). Many businesses start with manual or semi-auto lines and upgrade as volume grows.
