Silicone Coatable BOPET TTR Base Film Strong Backcoat Adhesion for Ribbon

Product Description / Production Introduction

This silicone coatable BOPET TTR base film is a biaxially oriented polyester film designed as the carrier for thermal transfer ribbons where a silicone or other functional backcoat is required. Its clean, uniform surface delivers strong backcoat adhesion, so the silicone layer bonds firmly and does not flake, rub off or peel during printing, protecting the print head and greatly extending ribbon and print head life. The ultra thin 4 and 4.5 micron gauge keeps material usage low and increases usable ribbon length per roll, while high tensile strength and toughness provide stable, break-free running at high printing speeds. Strict thickness control ensures an even coating weight and a consistent release force across the entire web and from roll to roll, which is essential for smooth ribbon payout and uniform print density. Low shrinkage and good dimensional stability keep the ribbon flat and registration accurate, avoiding wrinkles, twists and print misalignment, while high transparency and low haze keep the printed output sharp and bright. The film is supplied free from surface treatment so it accepts silicone, wax, resin and other coatings reliably, and it runs smoothly on high speed coating, slitting and spooling lines.

Key Features

Strong Silicone Backcoat Adhesion

The clean, uniform surface forms a firm bond with silicone and other backcoat formulations, so the backcoat layer does not flake or rub off during printing. A durable backcoat protects the print head, resists abrasion and dramatically extends ribbon and print head service life.

Receptive to Silicone and Functional Coatings

The film is supplied without corona treatment, giving a stable, contamination-free surface that wets out evenly with silicone, wax, resin and other functional coatings. This allows ribbon makers to apply a uniform backcoat with predictable adhesion and release behaviour.

Ultra-Thin 4 / 4.5 Micron Gauge

The ultra thin gauge lowers material consumption and increases the usable length per roll, so more ribbon fits in each cartridge and each kilogram of film delivers more printed labels.

High Tensile Strength and Tear Resistance

Thin yet strong, the film resists edge tear, stretching and web breaks under the tension of high speed printing and slitting, reducing downtime and print head jams on fast machines.

Uniform Thickness for Consistent Coating Weight

Tight gauge control keeps coating weight, release force and optical density uniform across the web and from roll to roll, so the ribbon performs consistently from the first metre to the last.

Low Shrinkage and Dimensional Stability

Low heat shrinkage keeps the ribbon flat and prevents curling and wrinkling in the heated print head, holding registration accurate for sharp, distortion-free print.

High Transparency and Low Haze

The clear, low haze base film keeps printed barcodes, text and graphics bright and legible for high resolution and high density thermal transfer printing.

Application Scenarios

Silicone Backcoated Ribbon Production - The primary application is as the base film for thermal transfer ribbons that carry a silicone backcoat. Strong backcoat adhesion ensures the release layer stays intact through coating, slitting, spooling and printing.

Print Head Protection and Long-Life Ribbons - Because the backcoat does not flake or rub off, it protects the print head from abrasion, extending print head life and allowing ribbons to run longer before replacement, which lowers total printing cost.

Wax, Wax-Resin and Resin Ribbon Systems - Suits all three mainstream ribbon chemistries, giving ribbon makers one reliable base film for wax, wax-resin and resin formulations across different print durability requirements.

High-Speed Coating, Slitting and Spooling - Even coating pick-up and clean edges let the film run at high line speeds with minimal defects, helping manufacturers increase throughput and reduce waste.

Industrial, Retail and Logistics Label Printing - Ideal for durable industrial, retail and logistics labels that must print sharply and resist rubbing and handling in demanding environments.

Flat-Head and Near-Edge Printer Ribbons - Well suited to ribbons used in flat-head and near-edge thermal printers, where backcoat quality and dimensional stability strongly affect print quality and head life.
