kartonointi

Kartonointi (Finnish for cartoning or boxing) refers to the process of packing products into cartons or boxes for protection, handling and presentation. The term is used in packaging industries to describe both manual and automated operations that erect, fill and close folded cartons made from paperboard, corrugated board or similar substrates.

Common methods include erect-and-fill, wraparound and tray forming. Erect-and-fill machines fold flat blanks into a box shape, insert the product and close the flaps; wraparound machines form the carton around the product; tray systems create shallow carriers for grouped items. Equipment ranges from handheld assembly to high-speed horizontal and vertical cartoners integrated with filling, labeling and sealing systems.

Kartonointi is applied across sectors such as food, pharmaceuticals, cosmetics and consumer goods, where protection, branding and regulatory information are important. Key considerations in cartoning are durability, ease of opening, display quality and compatibility with other packaging operations like primary packaging and palletizing.

Environmental and economic factors influence material choice and design: recyclable and recyclable-friendly boards, minimal material use and efficient nesting reduce waste. Quality control includes weight checks, seal integrity inspection and print verification. Advances in automation, sensors and modular machinery continue to improve speed, flexibility and traceability in kartonointi.
