USED CARDBOARD TRAY MAKING MACHINE HBJ 800 (MAX 400 x 600 MM)

Optimize your eco-friendly food packaging production with the highly efficient HBJ 800 Cardboard Tray Making Machine. This automatic carton erecting machine is designed to quickly form and glue flat cardboard blanks into rigid trays, lunch boxes, burger boxes, and other sustainable food containers. Supporting a maximum blank size of 400 x 600 mm, it provides excellent versatility for a variety of takeaway and retail packaging formats.

The creation of high-quality cardboard food trays requires a multi-step manufacturing workflow. Understanding these stages shows exactly where the HBJ 800 fits into your production line.

1. The Printing Process

First, the raw cardboard material (often food-grade Kraft or PE-coated board) is printed with branding, nutritional information, or appealing designs. This is typically done on high-speed offset or flexographic printing presses depending on the run size.

2. The Die Cutting Process

Once printed, the large sheets must be cut into the specific flat shapes (blanks) needed for the trays. An automatic flatbed die cutter punches out the contours and presses crease lines into the cardboard to ensure accurate, clean folds later in the process.

3. Print Finishing & Carton Erecting (HBJ 800 Workflow)

The final stage is turning the flat, die-cut blank into a usable 3D product. This is where the HBJ 800 Tray Making Machine operates.

• Feeding: Flat blanks are automatically fed into the machine from a magazine stack.
• Gluing: The machine precisely applies cold glue or hot melt adhesive to the specific flaps of the blank.
• Forming & Erecting: A mechanical plunger pushes the blank through a custom forming mold. This action folds the cardboard along the pre-creased lines and presses the glued flaps together securely.
• Delivery: The finished, structurally sound food trays are nested and ejected, ready for packing and shipping to food service clients.
