Quick Answer
The HPRT DC24E is a compact 203 dpi TTO date coder for intermittent VFFS, compatible HFFS/flow-wrap, and labeling lines. With a 24 × 15 mm print area, 500 m ribbon, mobile editing, and airless operation, it can replace hot-stamp coders for dates, batch numbers, serial numbers, 1D barcodes, and QR codes.
Before each run, hot-stamp coders require operators to reset brass type, verify date information, and wait for warm-up. A reversed character or incorrect expiry date can lead to packaging waste, rework, and line downtime. As SKU counts grow, manually managing dates, batch numbers, and traceability data becomes the real bottleneck.
Designed for new-machine integration and retrofit projects, the DC24E thermal transfer overprinter can mount on compatible existing hot-stamp coder brackets with minimal mechanical modification. It is particularly well suited to compact variable-data printing on flexible packaging films where installation space is limited and the packaging equipment operates intermittently.
What Coding Problems Does the HPRT DC24E Solve on Packaging Lines?
Selecting the right date coding machine is not always straightforward. Manufacturers must balance coding requirements, available installation space, integration effort, and cost.
-
●
Replacing hot stamp coders: Traditional hot-stamp coding requires preheating, brass-type setup, and individual character changes between production runs. Manufacturers seeking to reduce operator intervention and date-code errors need a simpler digital alternative.

●
Building or upgrading VFFS lines: Packaging-machine OEMs, manufacturers, and retrofit specialists often work with limited installation space and need to integrate a coder quickly with intermittent VFFS equipment or compatible labeling machines.
-
●
Looking for a narrow-format, cost-effective TTO solution: Many small and mid-sized manufacturers—including snack and dry-food producers and beverage and powdered-drink manufacturers—need to print only production and expiry dates, lot codes, serial numbers, or compact QR codes. Standard TTO printers may offer a larger print area and additional capabilities than these applications require, adding unnecessary equipment cost.
-
●
Reducing installation and control complexity: Space-constrained lines may need sensor-triggered printing and basic fault feedback without additional controllers, compressed-air infrastructure, or advanced industrial communication systems.
To address these challenges, the HPRT DC24E provides a compact, purpose-built date coding solution for intermittent packaging lines. Its mobile editing, instant start-up, 500 m ribbon, and airless design improve coding efficiency while simplifying integration into space-constrained packaging equipment.
Why Choose the HPRT DC24E for Intermittent Packaging Lines?
Digital Editing With Real-Time Status
Operators can edit production dates, expiry dates, lot numbers, and serial numbers from a smartphone instead of arranging brass type. The mobile interface displays real-time operating status, helping operators verify settings and reduce coding errors during SKU changeovers.
High-Speed Printing Without Preheating
The DC24E intelligent date coder is ready to print after startup, removing the warm-up delay associated with conventional hot-stamp coders. It supports packaging equipment operating at up to 200 packs per minute when printing fixed content with a 15 mm print length.
Dates, Barcodes, and Traceability Content
This expiry date coding machine prints on a range of flexible packaging films, including BOPP, BOPET, CPP, PE, and VMPET. It supports:
- ● Manufacturing and expiry dates
- ● Batch and lot numbers
- ● Real-time timestamps, accurate to the second
- ● Serial numbers
- ● 1D barcodes and QR codes
- ● Logos, graphics and custom text
Reduce Changeovers With 500 m Ribbons
The DC24E supports 500 m wax-resin and resin ribbons. When used with HPRT dedicated ribbons, it can deliver more than four times the prints per roll of conventional short-roll hot-stamp ribbon, helping reduce ribbon changeovers and lower coding costs per print.
Simple Packaging-Machine Integration
This date coding machine requires no compressed-air connection. It accepts 12–24 VDC NPN/PNP trigger signals and provides a volt-free fault output, simplifying integration with VFFS packaging machines, intermittent labelers and hot stamp coder retrofit projects.
What Packaging Applications Does the HPRT DC24E Support?
Intermittent VFFS Lines
The DC24E suits intermittent vertical form-fill-seal (VFFS) lines that produce sachets, stick packs, pillow bags, and other compact flexible packs.
- ● Powders and granules: coffee, milk powder, powdered drinks, seasonings, protein powder, and nutritional supplements
- ● Snacks and dry foods: nuts, candy, cereal, snack foods, and pet food
- ● Personal care and household products: shampoo sachets, detergent refills, cleaning-product packs, and cosmetic samples
- ● Pharmaceutical and healthcare products: powder sachets, granules, and single-dose health-product packs
Intermittent HFFS and Flow-Wrap Lines
The DC24E can support compatible intermittent horizontal form-fill-seal (HFFS) and flow-wrap equipment where the application requires short variable codes on flat film, sachets, or pouches.
- ● Tray-sealed ready meals and convenience foods: prepared-meal trays, chilled or frozen food trays, and meal kits with compatible lidding films.
- ● Bakery and confectionery: biscuits, snack bars, wrapped candy, and bakery products
- ● Chilled and frozen products: flexible portion packs, subject to film, temperature, and code-adhesion testing
- ● Health and personal care packs: supplement sachets, facial-mask pouches, and wet-wipe packs
Labeling and Hot-Stamp Coder Retrofits
The DC24E supports compatible intermittent labelers, packaging-machine OEM projects, and hot-stamp coder upgrades.
- ● Printing dates, batch codes, 1D barcodes, and QR codes on labels for bottles, jars, cartons, and other packaged products
- ● Integrating digital date coding into compact packaging and labeling equipment
- ● Replacing existing hot-stamp coders while retaining compatible mounting brackets
Pro Tip: Before installation, confirm mounting space, available dwell time, print position, sensor-trigger logic, ribbon-change clearance, and code quality on the final film or label material.

Is the HPRT DC24E the Right Date Coding Machine for Your Line?
The DC24E is a focused date coding machine for intermittent pouch packaging. It is strongest when a factory needs to move beyond traditional hot stamp coding but does not require a large print area or enterprise-level production control.
DC24E is a strong fit if:
- ✓The line uses an intermittent VFFS machine, a compatible intermittent HFFS or flow-wrap system, or a labeling system with limited installation space.
- ✓All required content fits within 24 × 15 mm.
- ✓The factory is replacing a brass-type hot stamp coder.
- ✓The application requires only basic variable-data coding, such as automatic dates, batch numbers, QR codes, or custom text.
- ✓The host machine only requires sensor triggering and basic fault feedback.
Consider another date coder if:
- ● The production line uses continuous-motion HFFS equipment.
- ● The package requires a large print area or long blocks of information.
- ● The application needs 300 dpi for dense, very small codes.
- ● The factory requires MES, ERP or complex multi-printer control.
- ● The project needs integrated vision inspection, audit trails or a higher IP rating.
