PVC Shrink Label Printing Machine – RK FMS-Nice-P 320 / 6 Colour Full Servo

A shrink label printing machine is a roll-to-roll press that prints shrink film – usually PVC, sometimes PET or OPS – which is later formed into a sleeve, cut and shrunk onto the product. The key demands are heat control (film must not stretch during drying), accurate registration on a substrate that moves easily, reverse printing (artwork on the inside of the sleeve), and drying that suits the ink system.

The RK shrink label machine meets these with a chiller drum after every printing unit, full servo drive with automatic block position registration, a turn bar for back side printing, and both UV and hot air drying on every unit. The published configuration is six colours on a 320 mm web; the FMS-Nice-P platform is also available in wider widths.

Six Colour Full Servo Flexo Printing

All six printing units, the die-cutting unit, the infeed and the outfeed are driven by individual servo motors – nine in total. Registration between colours is held electronically, which matters on shrink film where a small drift shows clearly once the sleeve is shrunk.

Chiller Drum on Every Printing Unit

Heat is the enemy of shrink film. Each printing unit runs the web over a chiller drum after drying, so the film stays cool and dimensionally stable. This is the feature that separates a shrink label machine from a general label press.

All UV Dryer and Hot Air Dryer

Each unit has an all UV dryer system (brand UV Rays / GEW, made in Italy / UK) and a hot air dryer, so the press can run UV inks or water-based and solvent-based inks as the job requires.

Automatic Block Position Registration

Every printing unit has automatic block position registration. Plates are brought into position electronically at the start of the job, which cuts setup waste on expensive film.

Turn Bar for Back Side (Reverse) Printing

Shrink sleeve artwork is printed on the inside of the film so it is protected once shrunk. The movable turn bar flips the web so the machine can print the reverse side in the same pass.

Delam-Relam and Cold Foil / Lamination

The movable delam-relam unit separates and rejoins layers for multi-layer work, and the movable cold foil / lamination unit adds metallic effects or a protective laminate inline. All three units are movable, so they are positioned where the job needs them.

Ultrasonic Web Guide and Load-Cell Tension Control

The unwinding unit uses an imported ultrasonic electronic web guide and an auto electronic tension controller with load cell feedback. The rewinding unit uses an electronic tension controller with load cell feedback and an independent motor and drive synchronised with the main drive through an encoder. Thin film needs this level of tension control to run flat.

Online Die Cutting With Waste Matrix Rewinding

The online die-cutting unit cuts inline and rewinds the waste matrix, so the machine can deliver finished rolls where the job calls for it.

The shrink film roll is loaded on the unwinding unit with the pneumatic loading system. The ultrasonic web guide keeps it centred and the load-cell tension controller keeps it at a steady, low tension suitable for film.

The web passes through the six printing units. At each unit a ceramic anilox roller meters ink onto the plate, the plate prints, the web passes through the UV or hot air dryer, and then over the chiller drum to bring its temperature back down. Where the job is reverse-printed, the turn bar flips the web so the artwork goes on the inside face. The delam-relam and cold foil / lamination units are used where the artwork calls for them.

After printing, the web passes through the online die-cutting unit if cutting is required, the waste matrix is rewound, and the finished film winds on the rewinding unit, whose independent motor is synchronised with the main drive through an encoder. The whole line runs from the touch screen.

The machine is configured for PVC shrink film and is suitable for other thin shrink films within the FMS-Nice-P substrate range of 12 micron and up. It also runs the self-adhesive stock, paper, BOPP and PET that the platform is designed for. Because film behaviour depends on gauge, ink system and drying, share your actual film samples with the RK team before the specification is fixed.

RK Label Printing Machinery Pvt. Ltd. has manufactured label printing and converting machinery in Ahmedabad, Gujarat since 1995, operates three manufacturing units and supplies customers in 23+ countries. For shrink sleeve producers, RK offers the complete chain from one supplier: the shrink label printing machine, the sleeve glueing machine and the sleeve cutting machine, all built to the customer's film and sleeve sizes rather than a fixed catalogue.

• Film type and gauge: PVC, PET or OPS, and the micron thickness, decide the chiller, tension and drying settings. Bring samples.
• Colours: six covers most shrink sleeve artwork; discuss eight if you run process work plus several spot colours and white.
• Reverse printing: confirm the turn bar arrangement suits your artwork orientation.
• Finishing inline: decide whether you need the online die-cutting unit, cold foil / lamination or delam-relam for your jobs.
• Downstream: plan the sleeve glueing and cutting machines alongside the press so the whole line is matched.
• Floor space: confirm the layout drawing RK provides, including the movable units.

The price of a shrink label printing machine depends on colour count, web width, drying system, chiller arrangement, the movable units included, anilox rollers, cylinder sets and options. Prices are quoted ex-works Ahmedabad with GST at 18% applicable; engineer transport and stay for installation and training at your site are borne by the customer. Share your film specification, sleeve sizes, colour count and monthly volume with RK and the engineering team will recommend a configuration and quote against it.
