Automotive Trunk Floor Panel Solutions

Lightweight, durable, and customizable trunk floor systems using PP Bubble Board and Honeycomb Panels

Engineered for strength and weight reduction, tailored for modern vehicle cargo systems

Polyreflex provides high-performance trunk floor panel solutions designed for automotive cargo area applications. Using advanced materials such as PP bubble board and fiberglass reinforced paper honeycomb panels (PHC), our solutions deliver an optimal balance of lightweight construction, structural strength, and long-term durability.

These trunk floor panels are widely used in passenger vehicles, SUVs, and electric vehicles, where load-bearing capacity, weight reduction, and resistance to daily wear are essential. Compared to traditional materials such as MDF or plywood, Polyreflex panels offer superior moisture resistance, improved durability, and greater design flexibility. With a wide range of customization options, including surface lamination and precision processing, our trunk floor systems can be tailored to meet diverse automotive design and performance requirements.

Application Overview

The trunk floor panel is a critical structural component in the automotive cargo area, serving as the base that supports luggage while protecting the spare tire compartment and lower body structure. It must combine high stiffness, durability, and lightweight performance to meet the demands of daily use and long-term reliability.

Polyreflex provides advanced material solutions including PP bubble board and fiberglass reinforced paper honeycomb panels (PHC), offering an optimal balance between performance and cost. Our trunk floor systems are widely used in passenger vehicles, SUVs, and electric vehicles, helping manufacturers achieve both structural integrity and weight reduction.
