Professional flight cases are required for transporting professional equipment (such as electronic equipment, lighting equipment, stage props, etc.). In order to cope with the risk of damage caused by high-altitude flights and frequent transportation, flight cases must be strong and durable. Usually, the material of such boxes is aluminum alloy or wood, but they are bulky or easily damaged. Now, TOPOLO has developed a new type of flight box panel – thermoplastic polypropylene honeycomb core sandwich panels. Its application on flight cases brings a more reliable and safer application experience.
UV Resistant Thermoplastic Honeycomb Panels
TOPOLO thermoplastic polypropylene honeycomb panel is a high-strength, lightweight composite material. It is manufactured using thermal lamination technology, using continuous fiber-reinforced thermoplastic sheet as the skin and polypropylene honeycomb as the core.
- UV resistant thermoplastic skin.
- Cover the surface with a wear-resistant protective layer.
- Glue-free thermal lamination process.

Performance Beyond Ordinary Materials
Thermoplastic Honeycomb Panel VS Wooden Board
- Lighter: Compared with wood, thermoplastic honeycomb panels can reduce the weight of flight boxes by an average of 30~40%, making bulky wooden boards a thing of the past.
- Waterproof & Corrosion Resistant: One of the fatal disadvantages of wooden boards is that they are not waterproof and are prone to moisture and rot. As an air box that often travels on the road, it needs to cope with various environments including rain, ice and snow. The emergence of thermoplastic honeycomb panels solves this problem well.
Thermoplastic Honeycomb Panel VS Aluminum Panel
- More Impact Resistant: The aluminum alloy skin is easily deformed by impact and difficult to recover. The impact strength and bending strength of thermoplastic honeycomb panels are 2 to 3 times that of aluminum composite panels of the same thickness. The skin of aluminum alloy is fragile, and hard objects will leave scratches on its surface, but thermoplastic honeycomb panels are more tough and general collisions will not leave scratches.
- Lower Cost: The cost of aluminum materials is much higher than that of polypropylene honeycomb and thermoplastic sheets, and its processing is more difficult. It is obvious that thermoplastic honeycomb panels are more cost-effective in manufacturing.
Thermoplastic Honeycomb Panel & Glue-bonded Honeycomb Panel
Higher Operating Temperature Range: No glue is used in the production of thermal honeycomb panels. The thermoplastic skin and honeycomb core are more closely combined. Its operating temperature ranges from -60℃ ~ 120℃. It enables the flight case to better cope with high and low temperature transportation environments.
