An Upgraded Material Solution for Modern Hard-Shell Luggage：Dedicated Thermoplastic Composite

Greatchip officially introduces its luggage-dedicated thermoplastic composite material. Designed as an upgraded shell material option for hard-shell trolley cases, this new composite integrates lightweight performance, impact resistance, surface durability, food-grade safety and recyclability into a single material platform.

The thermoplastic composite has been developed through years of luggage manufacturing practice, mold testing and material formulation optimization. It is intended to help global luggage brands create differentiated product lines while meeting growing market demands for lightweight travel, premium appearance, regulatory compliance and sustainable manufacturing.

1. An Upgraded Material Option for Hard-Shell Luggage Production

For many years, ABS and PC have been widely used as established luggage shell materials in the global luggage industry. Each material has formed its own application advantages in different product positioning scenarios.

ABS is often recognized for its cost efficiency and process stability, making it suitable for a wide range of entry-level and mid-range luggage products. PC has been widely adopted for its good impact performance and transparent or high-gloss surface characteristics, especially in mid-to-high-end hard-shell luggage lines.

However, as consumer expectations continue to rise, luggage brands are facing increasingly balanced demands: lighter empty weight for travel convenience, better impact resistance for airport handling, more durable surface texture for premium appearance, and safer, more recyclable material formulations for global regulatory and ESG requirements.

To address these evolving market needs, Greatchip has developed a luggage-dedicated thermoplastic composite that provides an alternative material solution for brands aiming to upgrade their hard-shell luggage performance.

2. Core Performance Advantages of Thermoplastic Composite

① Ultra-Light Weight

The thermoplastic composite reaches a density of only 0.97 g/cm³, offering a lighter material option compared with conventional ABS and PC.

Luggage Value: A 28-inch trolley case made of this composite can achieve a finished weight of approximately 1.9 kg, helping reduce empty luggage weight and potentially lowering excess baggage fees for end consumers. For brand owners, lighter weight can also support more competitive product positioning in the premium lightweight luggage segment.

② High Impact Resistance

The material achieves a notched impact strength of 240 J/m² and a tensile strength of 130 MPa. Its honeycomb multi-layer structure is designed to absorb, transfer and dissipate impact energy more efficiently.

Luggage Value: In luggage performance testing, finished trolley cases have passed 450 cycles of roller impact testing, showing good durability under repeated impact conditions. This makes the material particularly suitable for check-in luggage, family travel cases and products intended for frequent international travel.

③ Wide Temperature Stability

The thermoplastic composite maintains stable physical properties across a temperature range of -40°C to 80°C, showing good adaptability to different climate zones and long-distance shipping conditions.

Luggage Value: For brands exporting luggage to cold regions, high-temperature markets or cross-continental destinations, this material helps reduce quality risks caused by temperature changes during sea freight, air transport and storage.

④ 2H Scratch Resistance and Integrated Natural Texture

The surface pencil hardness of the material reaches 2H, providing natural scratch resistance without additional protective film. Through thermoforming, the material can form integrated matte, leather grain and jade-like surface textures.

Luggage Value: This can reduce the need for secondary painting or surface film lamination, helping streamline production processes. At the same time, natural leather grain and matte textures can support a more premium product appearance, especially suitable for mid-to-high-end luggage lines.

⑤ BPA-Free and Food-Grade Safety

The thermoplastic composite is formulated to be 100% BPA-free, with test results showing no formaldehyde, azo dyes, lead, cadmium or bisphenol A. It complies with EU REACH regulations.

Luggage Value: This makes the material suitable for children’s luggage, maternity travel cases and family travel sets, supporting brands to enter high-value consumer segments with higher safety requirements.

⑥ GRS-Certified Closed-Loop Recycling

The material is certified under GRS Global Recycled Standard Version 4.0. Production offcuts can achieve a reuse rate of over 45%, and the material supports recycling without washing or re-pelletizing.Luggage Value:For global buyers and retail chains with ESG requirements, this provides traceable recyclability documentation and supports sustainable product marketing without relying on unsubstantiated environmental claims.

3. Customizable Material Programming for Different Luggage Lines

One of the key advantages of this thermoplastic composite is its customizable material performance. Unlike traditional materials with relatively fixed properties, the composite can be adjusted through formulation and molding parameter optimization.

Greatchip's R&D team can tune the material for different product directions:

• Carry-on luggage: optimize thin-wall formability and lightweight performance

• Check-in luggage: enhance impact resistance and structural durability
• Premium luggage lines: develop matte, leather grain or jade-like surface textures
• Children’s and family luggage: emphasize food-grade safety and soft-touch appearance

This allows brands to build differentiated product portfolios without being limited by a single fixed material specification.

4. R&D Statement

“Luggage brands today need more than just basic shell materials. They need materials that can help them tell a clearer product story: lighter, stronger, safer and more sustainable,” said Greatchip's R&D Director- Mr. Miao,“With this thermoplastic composite, we are not replacing ABS or PC. Instead, we are providing an upgraded material platform that allows brands to design hard-shell luggage with better balanced performance, from user experience and production efficiency to global compliance.”
