Bag-in-Box Line for Bulk Packaging of Bread Rolls

A fully-automated bag-in-box line for the bulk packaging of bread rolls was installed overseas. The packaging line includes a carton erector, a poly bag inserter, two conveyor-based weigh fillers, a bag uncuffer and sealer, and a carton sealer.

The carton erector forms cartons into a rectangular box shape and seals the bottom with adhesive tape, creating a ready-to-use box.

The poly bag inserter lines pre-formed boxes with one poly bag each, ready for bulk packaging. The machine dispenses film from a roll into cartons, cuts and seals it into a bag, opens and cuffs the bag over the carton flaps, and blows air to expand the bag for a snug fit against the box's internal walls.

The weigh filler accurately portions and loads frozen bread rolls into the lined boxes via an inclined conveyor and a hopper.

This bag uncuffer and sealer is designed to heat-seal the bag tops inside the boxes. The machine uncuffs the bags from the carton top flaps, stretches the bag openings, applies a light vacuum to prevent ballooning, heat-seals the bags, and then flattens them within the box.

The carton sealer closes and then seals the box tops with adhesive tape.
