Product Description

Nobody gets excited about paper. It is, in the grand supply chain of maternity care, the thing that arrives in a box, gets loaded into the machine, and is quietly replaced when it runs out. But in the labour ward, the thermal trace that comes out of that paper is a legal document. It is a record that tells the story of how a baby came into the world. It is reviewed if something goes wrong. It gets retained for years under legal record-keeping requirements. The paper matters a great deal more than its status in the supply budget would suggest. Arrow CTG Paper is manufactured by Chhenna Corporation — a Delhi-based company that has been making medical chart papers under the Arrow brand since 1957. That is not a typo. More than six decades of manufacturing heritage in a very specific, very technical niche: thermal recording papers for cardiac, obstetric, and neurological monitoring equipment. Chhenna Corporation manufactures over 50 configurations of CTG paper alone, covering virtually every CTG machine brand in use globally — from Bistos and Bionet to Coromatrix, Cadence, Toitu, and Advanced Medical Systems among others. CTG paper — cardiotocography recording paper — is the thermal paper that runs through fetal monitoring machines in labour and delivery wards. It captures fetal heart rate patterns and uterine contraction data during labour monitoring. The paper speed is set at 1, 2, or 3 cm per minute, producing the characteristic gridded trace that obstetricians, midwives, and neonatologists are trained to interpret. The quality of the paper directly affects the quality of that interpretation: poor thermal response produces faded traces, poor grid precision makes measurement inaccurate, and paper that curls or jams mid-labour is not just an inconvenience. Arrow CTG paper is manufactured to medical-grade standards with smooth thermal coating for clear, dark, high-contrast traces; precise green or red grid lines at standard calibration; accurate sensor marks for machine synchronisation; and z-fold or roll formats as required by the specific machine. The paper is shrink-wrapped for moisture protection during transport and storage. For hospital supply distributors, medical equipment dealers, and institutional procurement managers sourcing consumables for labour and delivery departments — CTG paper is a predictable, high-frequency reorder. Every active CTG machine in every active labour ward consumes it continuously. Sara Wellness exports Arrow brand medical printing papers and other maternity care consumables to wholesale buyers across multiple markets. OEM specifications and custom configurations are available. Fifteen years of export experience means your paper arrives correctly, on time, and ready for the labour ward.

FAQ

Frequently asked questions

CTG paper — cardiotocography recording paper — is the specialised thermal paper used in fetal monitoring machines (cardiotocographs) during pregnancy and labour to record fetal heart rate and uterine contractions. Paper quality directly affects clinical interpretation: poor thermal sensitivity produces faint or patchy traces that are difficult to read; imprecise grid lines make measurement of trace characteristics inaccurate; paper that jams mid-recording can interrupt monitoring at critical moments. High-quality CTG paper produces clear, dark, sharp traces with precise calibration grids — enabling accurate interpretation of FHR patterns and uterine activity. CTG traces are legal medical records, retained for years under hospital record-keeping requirements, so print quality is not an aesthetic consideration but a clinical and medico-legal one.

Arrow CTG paper, manufactured by Chhenna Corporation, is produced in over 50 configurations covering a wide range of fetal monitoring machine brands used globally. Compatible brands include Advanced Medical Systems, Bistos, Bionet, Coromatrix, Cadence, Toitu, and many others. Since CTG paper dimensions and z-fold specifications vary by machine model, the correct paper reference must be matched to the specific CTG machine being used. Chhenna Corporation manufactures papers to OEM specifications and can match virtually any CTG machine requirement. Buyers should provide their specific machine brand and model when ordering to ensure the correct configuration.

CTG paper dimensions vary by machine brand and model. Common standard sizes include 150mm x 90mm (z-fold format, widely used in many standard CTG machines) and 152mm x 100mm (confirmed from supplier listings for specific machine types). Paper speed calibration is typically 1, 2, or 3 centimetres per minute. The paper is usually supplied in z-fold (fan-fold) format — which feeds continuously from a folded pack without unwinding from a core — though roll formats are also available for machine types that require them. Arrow/Chhenna Corporation manufactures over 50 CTG paper references, so the specific size and format must be matched to the exact machine model.

Medical-grade thermal paper, including CTG paper, is light-sensitive and moisture-sensitive. Arrow CTG paper is shrink-wrapped in protective packaging to prevent deterioration during storage and transport. It should be stored in a cool, dry environment away from direct sunlight, heat sources, and excessive humidity. Thermal paper typically has a shelf life of 2 to 5 years from manufacture when stored correctly. After opening, the paper should be used promptly and re-sealed where possible. Do not store CTG paper rolls or z-fold packs near chemicals, solvents, or other materials that may affect thermal coating sensitivity.

Z-fold (fan-fold) CTG paper is supplied as a pre-folded pack where the paper folds back on itself in continuous accordion fashion. It loads into the CTG machine paper compartment as a block rather than as a wound roll. Z-fold is the most common format for CTG machines because it feeds continuously without a core, allows easy checking of remaining paper quantity, and eliminates the curl associated with roll paper. Roll format CTG paper is wound on a central core, similar to a thermal receipt paper roll, and is required by some specific CTG machine models. The format required is determined by the machine design — both formats are available from Arrow/Chhenna Corporation.

Yes. Chhenna Corporation — the manufacturer of Arrow brand medical chart papers — manufactures CTG papers to OEM and customer specifications. Custom dimensions, z-fold lengths, roll core sizes, grid specifications, and OEM branding are all available for bulk orders. The company currently manufactures more than 50 CTG paper configurations covering machine brands from across the world. For wholesale buyers and distributors who supply multiple hospital clients with different CTG machine brands, mixed-SKU orders across multiple CTG paper configurations can be arranged through Sara Wellness.
