Flexographic printing, a widely adopted printing technique in the packaging industry, has undergone significant advancements in recent years. One notable area of innovation is slotting technology, which has revolutionized the way corrugated boxes are produced. This article explores the groundbreaking innovations in flexo printing and the transformative impact of slotting technology on the packaging industry.

Enhanced Slot Precision

Advances in slotting technology have significantly improved the precision of cutting slots in corrugated cardboard. High-precision slotting ensures that the slots align perfectly, resulting in a robust and consistent box construction. This improved precision minimizes variations in box dimensions, reducing the risk of box failure during storage and transit.

Reduced Makeready Times

Traditionally, slotting required extensive setup and makeready processes. However, innovations in flexo printing have introduced automated systems that streamline the makeready process, reducing downtime and improving production efficiency. Automated slotting machines can adjust to different slot configurations and materials with minimal operator intervention, significantly shortening makeready times and increasing productivity.

Versatility Across Substrates

Advancements in slotting technology have expanded its versatility to accommodate various corrugated substrates and coatings. Previously, slotting was primarily limited to single-wall corrugated cardboard, but new machines can now handle double-wall and even triple-wall substrates. Additionally, advancements in cutter design have enabled slotting on coated substrates, such as those with polyethylene extrusion or wax coatings, without compromising slot precision or box integrity.

Integrated Inline Processes

Flexo printing presses have integrated inline slotting processes, eliminating the need for separate slotting machines. This integrated approach simplifies the production process, reduces handling time, and minimizes the risk of damage to the printed material. Inline slotting systems also allow for real-time adjustments to slot dimensions and positioning, ensuring precise and consistent slotting throughout the production run.

Sustainability and Automation

Innovations in flexo printing have prioritized sustainability and automation to reduce waste and streamline operations. Advanced systems feature automated cutter blade positioning and programmable cutting patterns, minimizing material waste and maximizing production efficiency. Additionally, the use of recyclable materials and energy-efficient components contributes to a more environmentally friendly production process.


Innovations in flexo printing, particularly in the realm of slotting technology, have revolutionized the production of corrugated boxes. Enhanced slot precision, reduced makeready times, versatility across substrates, integrated inline processes, and a focus on sustainability and automation have transformed the packaging industry. These advancements have improved box quality, increased productivity, and opened up new possibilities for custom packaging solutions, meeting the evolving demands of modern businesses and consumers.
