The HYM-S300-25W-S corrugated board production line is the foundational investment for companies that want to produce corrugated board in-house, eliminating dependence on external suppliers, fully controlling material quality and significantly reducing the cost per square meter of board compared with buying on the market. The compact structure and modern design make this corrugated board production line a suitable solution both for new plants and for expanding the capacity of existing ones.
The components of the HYM-S300-25W-S corrugated board production line
Shaftless mill roll stand
The shaftless mill roll stand of the corrugated board production line allows quick roll changes without having to extract a central shaft, significantly reducing roll-change time compared with classic shaft systems and eliminating the risk of damaging the roll edges during mounting.
Fingerless vacuum single facer
The fingerless (no guide fingers) vacuum-suction single facer of the corrugated board production line forms the corrugated layer of the board by pressing the paper between two corrugating rolls, with the vacuum system ensuring precise transfer of the corrugated sheet onto the base liner without physical contact from guide fingers, a more advanced technology than classic fingerless systems, which reduces surface defects and improves the quality of the corrugated layer.
Preheater rolls
The preheater rolls of the corrugated board production line preheat the paper before corrugating and gluing, ensuring that the material's temperature and moisture are within optimal parameters for correct corrugation and complete bonding of the layers. Proper preheating reduces the risk of layer delamination and improves the ECT (Edge Crush Test) strength of the finished board.
Glue making system
The starch-based glue preparation and dosing system of the corrugated board production line ensures the consistency of the mixture and precise dosing of adhesive onto the corrugated layer, guaranteeing uniform bonding across the entire board width and throughout production, with no quality variation between batches.
Double bridge
The double bridge of the corrugated board production line accumulates a buffer of single face (corrugated board with a single liner bonded) before entering the double facer, compensating for speed differences between the corrugating and laminating sections and allowing continuous line operation even during roll changes.
Double facer
The double facer bonds the second liner onto the single face produced by the corrugator, forming complete corrugated board (single wall CO3 or the base for double wall CO5). The temperature-controlled pressing system ensures complete bonding of the layers across the full board width at the high production speeds of the HYM-S300 line.
Slitter scorer
The slitter scorer of the corrugated board production line slits the board sheet longitudinally to the required widths and creates the scoring lines that facilitate subsequent folding, with computerized adjustment of knife positions and scoring depth.
Cut-off machine
The cut-off machine cross-cuts the board sheet to the ordered lengths with precision, synchronized with the speed of the corrugated board production line to produce exact formats without additional material waste.
Stacker
The stacker automatically stacks the finished corrugated board sheets at the production-line outfeed, preparing them for transfer to printing, slotting and die-cutting equipment (the HS, HX, HUAYU series) or for delivery as raw board to customers.

Why produce corrugated board in-house: the advantages of investing in the HYM-S300 line
The HYM-S300-25W-S corrugated board production line fundamentally transforms the plant's packaging-material supply model. Instead of buying corrugated board sheets from external suppliers (with variable prices, unpredictable lead times and quality dependent on the supplier's choices) the plant produces corrugated board in-house to exactly the required specifications: width, length, thickness, structure (single wall, double wall), grammage and the paper type for each layer.
Full quality control is the first major advantage: the plant can independently adjust corrugating parameters, gluing temperature, paper tension and production speed to produce board with the exact ECT, BCT strength and moisture required by the packaged products. The second advantage is economic: the cost per square meter of board produced in-house is significantly lower than the market purchase price, with a margin that grows with production volume. The third advantage is flexibility: the HYM-S300 corrugated board production line can produce custom formats to order, eliminating stocks of standard-format board sheets that do not perfectly match production requirements.
Applications and industries for the HYM-S300-25W-S corrugated board production line
The HYM-S300-25W-S corrugated board production line is intended for integrated packaging plants that process large volumes of corrugated board and want to control the entire production chain in-house: from the raw paper roll to the finished printed, die-cut and glued box. The vertical integration provided by this corrugated board production line eliminates dependence on external suppliers and allows continuous optimization of material specifications according to customer orders.
Manufacturers of furniture, household appliances, industrial equipment and construction materials that consume large volumes of thick corrugated board packaging (double wall, triple wall) invest in the HYM-S300 corrugated board production line to produce their packaging material in-house at production cost, eliminating board suppliers' commercial margin and ensuring immediate material availability without dependence on external stocks.
Packaging plants that supply printed and die-cut boxes to large industrial manufacturers or major retailers benefit from integrating the HYM-S300 corrugated board production line with the processing equipment in the UZINEX portfolio (the HS, HX, HUAYU-A, HUAYU-B series) for a complete production flow: from roll paper to the finished printed, folded or glued box, under one roof.
Integration with UZINEX processing equipment
The HYM-S300-25W-S corrugated board production line produces corrugated board sheets that are processed directly on the printing, slotting and die-cutting equipment in the UZINEX portfolio. The HUAYU-A and HUAYU-B series (roller printer slotter die-cutters for board up to 11 mm) and the HS and HX series (HD vacuum flexo printing machines) are the natural downstream equipment for the board produced on the HYM-S300 line.
A plant that operates the HYM-S300 corrugated board production line together with a printer slotter die-cutter from the HUAYU or HS series, completed by a folder-gluer from the HS-A, HS-B or YF-Z series, has a fully integrated production flow: from the raw paper roll to the finished glued box bundled for shipping, with total control of quality and cost at every stage. UZINEX provides consultancy to size and configure a fully integrated flow.
Frequently asked questions about the HYM-S300-25W-S corrugated board production line
What types of corrugated board can the HYM-S300-25W-S line produce?
In its standard configuration the HYM-S300-25W-S corrugated board production line produces single wall corrugated board (CO3, 3 layers: liner + fluting + liner) and can be configured for double wall board (CO5, 5 layers) by adding a second single facer unit. The flute structure (type B, C, E, BC, EB, etc.) depends on the corrugating rolls installed; UZINEX provides consultancy to select the optimal structure according to the customer's packaging applications.
What is the maximum production width of the HYM-S300 line?
The HYM-S300-25W-S model designation indicates a working width of 2500 mm, one of the standard industrial widths for corrugated board production lines, suited to plants with medium and high production volumes. The corrugated board production line can produce sheets at any width from the minimum up to 2500 mm, with the slitter scorer slitting longitudinally to the ordered widths.
How much factory floor space does installing the HYM-S300 corrugated board production line require?
Complete corrugated board production lines are large-scale equipment: the total length of a complete line with all the components listed can exceed 80–120 meters, with a width of 3–5 meters and a height of 4–6 meters. UZINEX carries out a detailed assessment of the available space during the free technical consultancy and configures the HYM-S300 corrugated board production line for the customer's specific hall layout, optimizing material flow and access for maintenance.
How does the HYM-S300 line integrate with the downstream processing equipment in the UZINEX portfolio?
The sheets produced on the HYM-S300 corrugated board production line are the raw material for the entire range of UZINEX downstream equipment. The typical flow: the HYM-S300 line produces sheets → the HUAYU-A/B machines (roller printing + slotting + die-cutting, for board up to 11 mm) or HS/HX (HD vacuum flexo, for complex graphics) process the sheets into die-cut boxes → the YF-Z, YF-C, HS-A/B/C/T folder-gluers or the YF-ZD/YF-D stitching machines assemble the finished boxes. The flow is configured according to the plant's product portfolio; UZINEX sizes the capacities to avoid bottlenecks between stages.
What is the economic threshold for investing in a complete line versus buying sheets from external suppliers?
The concrete economic threshold depends on the cost per square meter of externally purchased board and the annual volume processed. Typically, the HYM-S300 corrugated board production line is economically justified at consumption above 8–12 million m² of board/year: at this volume, external suppliers' commercial margin (15–25% over production cost) plus transport and storage costs significantly exceed the amortization of the line investment. Below 5 million m²/year, external purchasing remains more efficient; between 5 and 12 million m²/year the decision depends on local board prices and the need for control over specifications. UZINEX prepares a detailed business case during the free consultancy.
What is the practical difference between single wall (CO3) and double wall (CO5), and when should I invest in the dual single-facer configuration?
Single wall (CO3) is the 3-layer structure (outer liner + fluting + inner liner), typical thickness 2–4 mm, suited to standard packaging for light to medium-weight products (food, FMCG, e-commerce, electronics). Double wall (CO5) has 5 layers (liner + fluting + liner + fluting + liner), thickness 6–8 mm, required for heavy industrial packaging, furniture, appliances and export on high-stacked pallets. The dual single-facer configuration on the HYM-S300 line enables double wall production without an intermediate processing step, efficient when over 30–40% of the plant's portfolio requires CO5. Below that threshold, a single wall configuration plus external purchasing for the rare double wall cases may be more economical.
Is the HYM-S300 corrugated board production line eligible for European-funded projects?
