Daily Snack Factories Struggle with Box Size Changes

Alyssa/ November 20, 2025 Return

Ever seen a packaging line fall apart just because the box size changed?
If you work in a snack factory, you probably know this pain too well. New SKU = new box. New box = chaos. Workers stop, complain, and the whole line slows down.

Many U.S. snack brands launch new flavors every month, which means the box size changes constantly. Manual packing just can’t keep up. People fold slower, boxes don’t line up, and shipments get delayed.

That’s why more factories are switching to UBL’s automatic cartoning machine, which can adjust to different box sizes fast — smooth changeovers, neat folds, tight seals. One operator can handle the whole line without stopping production.

One granola bar factory told us: “We no longer fear new SKUs. The machine changes faster than our marketing team decides flavors.”

When flexibility improves, the entire factory feels lighter.
