If you want to make board at industrial speed, straight from the paper reel, a complete cardboard production line is the solution that brings the whole process into your plant. The MECVORA model makes 3, 5 and 7 ply board, plus multi-function variants, through a continuous, automated flow: unwinding, pre-heating, corrugating, laminating, drying and cut-to-size. It is the right choice for packaging plants that want to move from buying board to making their own, with full control over quality and cost per square metre.
This cardboard production line covers 3, 5 and 7 ply on the same plant, with steam heating, a compressed-air system and its own glue-making system. It fits into a factory flow alongside printing, slotting and die-cutting, as a continuous source of board. Explore the rest of the MECVORA corrugated carton machinery range to complete your plant.
Benefits of an automatic corrugated line
Your own cardboard production line changes the economics of a packaging plant: it removes dependence on board suppliers, stabilises your raw-material cost and gives you control over deadlines. Instead of buying board at market price, you make it in-house, to the exact specification needed for quality board production. Here are the concrete benefits you look for:
• Continuous, automated flow, raw paper enters the unwinder and leaves as board cut to size, with minimal operator intervention.
• 3, 5 and 7 ply on one plant, a 3 5 7 ply line covers everything from everyday boxes to heavy transport packaging.
• High production speed, sized for industrial volumes, it continuously feeds the downstream conversion sections.
• Predictable cost per square metre, in-house production removes the board supplier mark-up and the middleman margin.
• Consistent quality, pre-heating and the glue system deliver flat board, free of delamination, batch after batch.
• Integrated systems, steam heating, compressed air and glue making, designed to work together.
• Format flexibility, working width and speed are chosen to match your order profile and the space available in your production hall.

Applications and industries for board production
A cardboard production line of this type serves packaging plants that make board for regular slotted cases, e-commerce boxes, food packaging, appliance boxes and shipping cartons. In-house board production means board no longer comes from an outside supplier but is made to exactly the flutes and grammages that fit your orders.
Packaging suppliers for retail and distribution use the line as a continuous source of board for their printing and conversion sections. The equipment meets the requirements applicable to CE-marked industrial machinery, in line with the EU Machinery Regulation 2023/1230. Discuss the right configuration with the UZINEX team.
For fast-growing plants, your own cardboard production line shortens the supply chain: you no longer depend on board deliveries and no longer pay to transport a bulky material. The 7 ply output covers heavy, palletisable packaging, while 3 ply stays available for everyday boxes, all on the same plant.
In growing markets, especially in e-commerce packaging, demand for board swings sharply. An automatic corrugated line lets you scale volume up or down without renegotiating with suppliers, respond to peak seasons and accept large orders without turning clients away for lack of board. Production capacity becomes a commercial tool rather than an external limit.
For exporters and large converters, logistics also matter: shipping finished board over long distances is expensive because of its bulk. In-house production cuts those costs and delay risks, while storing liner and fluting instead of finished board frees up significant warehouse space. The same line can also switch quickly between grammages for different clients, turning order variability into a competitive advantage.
Compatible materials
This cardboard production line processes the usual papers for making board. The flute types and combinations below are indicative and are confirmed according to the configuration and the board you want.
| Element | Notes |
|---|---|
| Liner paper (Kraft, testliner) | the outer faces of the board |
| Fluting paper (medium) | the inner corrugated layers |
| A, C flutes | compression strength, transport packaging |
| B, E flutes | smooth surface, fine print, retail boxes |
How it works
The workflow on a cardboard production line is continuous and automated, from paper reel to board cut to size:
1. The raw paper reel is mounted on the mill roll stand and fed into the line.
2. The paper is heated and moisture-conditioned by the pre-heater.
3. The single facer corrugates the paper and glues it to the liner, forming single-faced board.
4. The single-faced board passes over the conveying bridge to the laminating section.
5. The glue application machine and double facer bond the plies into continuous board.
6. The slitter scorer, cut-off, conveyer and stacker cut, crease and stack the board to size.
Because the process is automated, a well-tuned cardboard production line delivers uniform board for hours with minimal intervention. Switching between 3, 5 and 7 ply is done from the control system, and production is planned around your deadlines, not around an outside board supplier's availability. A trained crew supervises the wet end and dry end, stepping in mainly at grade changes.
Pre-heating and glue-control systems keep the board flat even at high speed, while the dedicated glue-making system ensures even consumption. In practice, this means fewer rejects, board with stable physical indices and a predictable operating cost over the long term, essential for a large investment like a production line. Automatic counting and cut-to-size also reduce trim waste and simplify production planning.
Frequently asked questions
What does a 3, 5 and 7 ply cardboard production line make?
It makes 3, 5 and 7 ply corrugated board, plus multi-function variants, starting from raw paper reels and delivering board cut to size, ready for printing and conversion. The same line covers everything from everyday boxes to heavy transport packaging.
What speed and width does this board production have?
Speed is roughly 150 to 250 m/min, and working width is usually between 1,400 and 2,500 mm. Exact values are set in the quote, according to your hall space and volumes.
What infrastructure does a line of this type require?
The line needs a suitable hall, a steam source (boiler), compressed air, electrical supply and a water source. In the personalised quote we detail the exact siting and utility requirements, according to the configuration, including approximate floor area, ceiling height and the boiler capacity matched to your target line speed.
How long is the payback on a cardboard production line?
It depends on the volume of board produced and the gap between in-house cost and supplier purchase price. For plants with steady board consumption, an in-house cardboard production line sharply cuts cost per square metre; we work out a scenario on your real volumes together.
What does installation and commissioning involve?
Transport, installation, commissioning and operator training are provided by the UZINEX team. Before delivery, components go through a check, so the line becomes operational as quickly as possible, with no hidden costs.
Can printing and conversion sections be integrated downstream?
Yes. The line produces continuous board, and downstream you can add flexo printing, slotting, die-cutting and finishing. That gives you a complete flow, from paper reel to finished box, with board production under your own control.
Is the equipment suitable for EU co-financed projects?
Yes. It ships with CE-compliant components and the related conformity documentation, which makes it eligible for co-financed investment projects. On request, we provide the certifications and technical sheets needed for the file.
