Automatic  and semi-automatic forming of cardboard boxes from flat blanks

Carton erectors, also called box folding or box preparation machines, automatically convert flat corrugated cardboard blanks into three-dimensional boxes. These machines open the blank, fold the bottom flaps and seal them, creating a stable box ready for filling for subsequent packaging processes.

A carton erector automates  the most labor-intensive stage of secondary packaging.

1. Takes a flat corrugated cardboard blank from the magazine.
2. Opens the blank and gives it a three-dimensional rectangular shape.
3. Folds the bottom flaps.
4. Seals the bottom using adhesive tape or hot-melt glue.
5. Discharges the formed box onto the conveyor.

Modern carton erectors can handle different box sizes, and provide fast tool-less format changeovers.

Carton erectors are widely used for:

• Shipping cases for food, cosmetics, consumer goods, etc.
• Secondary packaging in retail.
• Frozen food logistics cases.
• Transport of beverages and dairy products 
• Packaging snacks and confectionery products.

The machines are designed to work with corrugated cardboard cases, which are commonly used in food supply chains, pharmaceutical distribution, cosmetics and consumer goods manufacturing, as well as logistics — anywhere transport packaging is required.

Together these machines create a continuous, automated line flow.

When cases are filled with product, the sealer:

• Folds the top flaps.
• Applies adhesive tape or glue.
• Discharges the sealed cases back onto the conveyor.

It guarantees closure and protects products during handling and transport.

In food production, carton sealers are used for:

• Shipping cases with packaged food.
• Transport cases for frozen products.
• Beverage and dairy logistics.
• Large-volume food service (HoReCa) packaging.

Automated sealing reduces human contact and helps comply with hygiene standards. In pharmaceutical and medical goods supply chains, automated sealing helps ensure packaging protection against unauthorized opening (tamper-evidence), transport safety and compliance with regulations, especially when combined with serialization, marking or inspection systems.

Strapping machines provide an additional layer of load security by wrapping plastic or textile straps around sealed cases or packaged bundles.

They are typically used when:

• Cases are heavy.
• The load requires additional stability.
• Products are stacked in piles before palletizing.
