Carton Edge
Carton Edge is built for carton and board work where the heated zone must stay tight along an edge, flap or narrow printed strip. It suits packaging lines that cannot afford stray heat across varnished panels, glued seams or unprinted stock.
Narrow heat for carton edges
Carton Edge is aimed at packaging work where heat must be directed neatly along a board edge or narrow print area. That makes it useful for lines where a broad flash field would put unnecessary heat into the rest of the carton.
Board grade, ink laydown and line speed should be checked first when planning a Carton Edge unit. Inland dust can settle on reflectors, while coastal moisture changes how quickly a test panel reaches target cure, so settings should be logged against the actual carton stock in use. Johannesburg, Durban and Cape Town packaging plants often need a narrower heat pattern than a garment flash head would give.
Include a photo of the print lane, guides and board width before the unit is matched to the line. That reference helps when noting heater height, pass distance and the exact section of the carton that must receive heat.
What to record on this line
The useful paperwork for Carton Edge is not general packaging theory but the line note and cure log tied to the job. Record the board size, printed band width, conveyor or indexing speed, and any spare requirement so the same setup can be checked before another run starts.
Add Carton Edge to the matching line note and the cure log before you widen the scope. Check the line details again before any unit or spare leaves our side. Dryer sizing depends on belt width, ink type and the pieces you run per hour, so list those in your message.
- Heated zone matched to board edge
- Photo of guides and print area
- Spare request linked to exact unit
Checks that matter in packaging
Carton Edge should be checked against the current line details before any unit or spare is sent out. Guide rails, carton width, print position and any adjacent glued section can change whether ceramic IR or a quartz bank is the better fit for the heat pattern needed.
Dust buildup on packaging lines can dull reflector performance, so wipe intervals should be part of routine maintenance. After a power interruption, run a fresh test on the same board stock rather than relying on the previous shift's temperature setting.

Carton Edge line information
Use the contact form, mention Carton Edge, and give the carton sizes you print. It also helps to include the carton type, the width of the printed strip and whether heat must stay clear of folds, glue areas or coated faces.
If there has been a failed cure, edge curl or marking outside the printed band, note that with the line record. Those details make it easier to place Carton Edge against the correct packaging application and keep the cure log accurate.
