Corrugated Line
Corrugated Line focuses on flexo press routes for corrugated board, die-cut blanks, and outer cases used in transit packaging. The page speaks to carton and box plants that run heavier sheet or board grades where sheet feed, board flatness, and print repeat matter on every order.
Board grades and box formats
Corrugated Line covers flexo press paths for board and corrugated packaging work. It is aimed at plants that need dependable print on heavier stock, with attention to feed, handling, and repeatable output.
Start with flute profile, sheet size, print area, and the type of pack being made. Kraft liners, white-top board, and pre-printed laminates each place different demands on ink laydown, drying, and impression. Plants around Johannesburg, Durban, and Cape Town often also need the press route checked against power stability, handling space, and dispatch timing for regular packaging work.
A site walk-through should cover feeder condition, sheet path, anilox selection, and registration checks before any run plan is fixed. Dust build-up, worn feed wheels, or uneven board stacks can show up as print variation long before ink is blamed. Keep a simple start-up sheet at the machine so settings from the last acceptable run are easy to compare.
Output checks for corrugated work
The outcome should identify the press type, board application, ink system, and the key control points for repeat work. For corrugated jobs, that usually means clear notes on feed consistency, print coverage, drying, and sheet handling after print. A shorter, usable run plan is worth more than general notes that do not match the plant.
Use the matching product notes before adding extra converting stages or wider print requirements. If equipment is moving through Durban Port, compare the dispatch record with sheet width, board thickness range, and site access before unloading is booked. In the contact form, say it is for a corrugated line and give the board grades you run.

Operating conditions at SA plants
Planning for corrugated work in South Africa often needs more than print width and speed. Export cartons, warehouse packs, and shelf-ready outers can all require different board specs, bundle counts, and handling methods at the receiving site. Older plants may also need turning space, stack height limits, and forklift movement checked before a larger line is considered.
Coastal humidity can affect board flatness and drying behaviour, while inland dust can interfere with sensors, gears, and daily clean-downs. Load-shedding or unstable supply may change when makeready, ink circulation, and first approval are safest to schedule. Those conditions matter on corrugated lines where sheet handling is less forgiving than lighter web work.

Information needed for board runs
Send sheet sizes, flute type, box style, and clear photos of the feeder, print units, and delivery end. Mention whether the work is plain transit cases, retail-ready outers, or multi-colour display packs. Note any recurring faults such as edge crush, scumming, weak solids, or registration drift.
Keep the Bloem count sheet with the latest layout, board grade, and print repeat while the buyer documents are still current. File it with the project record and supporting papers so the receiving team can check the machine setup against the approved scope.
