Summary

Discover the advantages of PP Bubble Board and why it's an ideal lightweight, durable, and eco-friendly alternative to traditional materials like plywood and solid plastic sheet in automotive applications. Learn more from Polyreflex, a trusted Chinese manufacturer with 18 years of experience.

What Is PP Bubble Board and What Are Its Advantages?
PP Bubble Board is an innovative lightweight plastic sheet made from polypropylene (PP), designed with a unique three-layer structure — two flat outer layers and a bubble-shaped core in the middle. This design gives the sheet a perfect balance of strength, durability, and light weight, making it a popular material in industries like automotive, packaging, logistics, and construction.
Polyreflex is a leading manufacturer of PP Bubble Board in China, with 18 years of experience in production and customization. We supply high-quality PP Bubble Boards in various thicknesses, weights, and colors to meet diverse application needs.
Structure of PP Bubble Board
PP Bubble Board is made through a co-extrusion process that forms:
  • Top surface layer – Flat and smooth for printing, lamination, or welding
  • Bubble core layer – A middle layer filled with air bubbles, reducing weight while maintaining rigidity
  • Bottom surface layer – Similar to the top, for structural balance
    • This structure makes it lighter than solid plastic sheets while offering better impact resistance than corrugated or hollow-core sheets.
    Key Advantages of PP Bubble Board
    1. Lightweight yet Strong
    The bubble core reduces the overall weight by up to 40% compared to solid PP sheets, without compromising on strength or stiffness.
    2. Excellent Impact Resistance
    The air-filled bubble structure absorbs shocks effectively, making it ideal for protective packaging and automotive interiors.
    3. Waterproof and Chemical Resistant
    PP material is naturally resistant to moisture, oil, and most chemicals — suitable for outdoor and harsh environments.

    4. Eco-Friendly and Recyclable
    Made from 100% polypropylene, PP Bubble Board is fully recyclable and free from harmful substances like heavy metals or halogens.
    5. Thermoformable and Easy to Process
    It can be easily cut, CNC-machined, welded, or thermoformed into various shapes and components.
    6. Printable Surface
    The flat surface allows for screen printing, digital printing, and lamination, making it suitable for signs and branding.

    What Traditional Materials Can PP Bubble Board Replace?
    PP Bubble Board offers a smart alternative to several conventional materials, especially in applications that require a balance of lightweight, durability, and recyclability. Here are some of the most common materials that PP Bubble Board can effectively replace:
    1. Plywood and MDF (Medium Density Fiberboard)
    Used in trunk floors, door panels, and cargo liners, plywood and MDF are heavy and prone to moisture damage. PP Bubble Board offers a lighter, waterproof, and recyclable alternative with similar strength.
    2. Corrugated Paperboard
    Widely used in packaging, corrugated cardboard is not durable in humid conditions and is typically single-use. PP Bubble Board provides a reusable, moisture-resistant solution with higher impact strength.
    3. Solid Polypropylene or Polyethylene Sheets
    Although solid plastic sheets are strong, they are heavier and more expensive. PP Bubble Board achieves comparable rigidity with significantly less weight and material cost.

    4. PVC Foam Board
    Often used in signage and interior panels, PVC foam boards are heavier and less environmentally friendly. PP Bubble Board is halogen-free, more eco-conscious, and easier to recycle.
    5. Aluminum Composite Panels (ACP) in Non-Structural Applications
    In temporary partitions or interior auto components, ACP is often over-engineered. PP Bubble Board serves as a cost-effective, easier-to-process alternative that is also recyclable.
    Applications of PP Bubble Board
    Thanks to its combination of properties, PP Bubble Board is widely used in:
  • Automotive trunk floors, door panels, battery protection covers
  • Reusable packaging boxes and pallet sleeves
  • Protective lining for tool cases and transport containers
  • Outdoor advertising boards and exhibition panels
  • Construction floor protection and wall cladding
    • PP Bubble Board Trunk Floors
