Upgrade Your Printing Board: Discover Our Matte PP Honeycomb Sheets
In the world of advertising, signage, and display printing, the quality of the substrate can make or break the final result. While corrugated plastic sheets remain a popular choice for many signage applications due to their affordability and light weight, they may not always meet the requirements for projects that demand higher rigidity or a premium print finish.
At Polyreflex, we've developed a solution that overcomes these limitations: our matte PP honeycomb sheet. Designed for professional printing applications, this advanced material offers superior rigidity, a premium surface finish, and complete customization to meet the highest standards of the printing industry.
What Is a PP Honeycomb Sheet?
A PP (polypropylene) honeycomb sheet is a rigid, lightweight plastic board made of a multi-layered structure: a honeycomb-patterned core sandwiched between two flat outer layers. This structure gives the sheet excellent strength-to-weight ratio, outstanding dimensional stability, and a consistently flat surface, making it ideal for applications that require printing, mounting, or forming.
Polyreflex's PP honeycomb sheets are further enhanced with a matte, corona-treated surface on both sides, ensuring high-quality ink adhesion and a flawless appearance after printing.
Why Choose Polyreflex PP Honeycomb Sheets for Printing?
Our printing-grade PP honeycomb board is specifically engineered to meet the needs of display manufacturers, sign makers, and industrial printers. Here's what sets it apart:
1. Matte & Smooth Finish – Perfect for High-Quality Printing
The sheet's surface is micro-textured and anti-glare, providing a professional matte appearance that avoids unwanted reflections in brightly lit environments. This smooth finish ensures crisp image transfer and excellent color accuracy, whether you're using UV flatbed, screen, or solvent printing.
Unlike corrugated plastic with its fluted texture, our PP honeycomb board has no surface undulations or shadows—just a clean, even surface from edge to edge.
2. Bright White & Fully Opaque – True Color Output
We manufacture our sheets using a pure white PP resin formulation that is non-translucent, even under strong light sources. This eliminates background interference and ensures that printed graphics appear bold, vivid, and true to color.
Ideal for indoor or outdoor use where consistent visibility and color clarity are essential.
3. Double-Sided Corona Treatment – Superior Ink Adhesion
Each side of the sheet is treated with corona discharge technology to increase surface energy, reaching a dyne level of 42 or higher, allowing inks to bond quickly and permanently.
  • Suitable for both single- and double-sided printing
  • Supports screen, digital, UV, and offset printing methods
  • Prevents ink smearing, peeling, or fading
    • 4. Rigid & Ultra-Flat – No Warping or Bending
    The honeycomb core provides superior structural strength, allowing the board to remain flat and stable even in larger sizes or under environmental stress (e.g., humidity, heat, handling). This means:
  • Easier feeding into printers
  • No edge curling
  • Perfect results when mounting or framing
    • Even at 3mm thick, the honeycomb sheet offers excellent stiffness and flatness, making it a great choice for applications that require added structural strength compared to traditional corrugated plastics.
    5. Lightweight Yet Durable – Easy to Handle, Hard to Break
    At just 1000gsm for 3mm thickness, this board is light enough for ceiling hanging displays or transportation-heavy projects, yet sturdy enough for repeated handling or outdoor mounting.
    It's the ideal balance between portability and performance.
    6. Customizable in Every Way
    Whether you're a printer, distributor, or brand owner, Polyreflex can deliver exactly what you need:
  • Thickness: 3mm 4mm 5mm (standard), or customized up to 12mm
