Increase cartoning speed for delicate chocolate bars
In chocolate bar packaging, increasing speed is not the difficult part. The challenge is what happens to the product when you do.
At higher throughputs, small inconsistencies become visible. Bars start to shift, trays can deform, cartons lose their shape, and handling becomes less controlled. Especially with premium products, that’s the point where quality begins to erode.
High speed, without losing control
Solutions like the VENTO-c from Mpac Group are built for that exact moment.
This is a side-loading, continuous motion cartoner designed to operate at up to 500 cartons per minute—not as a theoretical peak, but as a stable production reality. At those speeds, the focus shifts from output alone to how the product is handled throughout the process.
The side-loading principle plays an important role here. Instead of dropping products vertically into a carton, trays are inserted horizontally in a controlled motion. That reduces the risk of product movement or impact during loading, which becomes increasingly critical at higher speeds.
Combined with continuous motion and servo-driven control, this allows product groups to move through the system in a more stable and predictable way. For chocolate bars packed in trays, where alignment and presentation matter, that level of control directly translates into consistent pack quality.
Premium packaging is about consistency
What defines systems at this level is not a single feature, but how consistently they perform across different conditions.
At high speed, carton quality needs to remain stable, products must be transferred without damage, and format changes should not disrupt the rhythm of the line. This becomes even more critical when running multiple SKUs, where maintaining consistency across variations is often more challenging than reaching peak output.
This is also where side loading continues to show its value. Because the product is supported and guided during insertion, rather than dropped, the process remains more controlled—even when conditions are not perfectly uniform.
For premium chocolate products, packaging is not just a functional step. It is part of the product experience, and any loss of control quickly becomes visible to the end customer.
