TPU films offer numerous advantages when applied to luggage

TPU films offer numerous advantages when applied to luggage. Here are the specific details:

Performance Advantages
Lightweight: TPU films are lightweight. When combined with fabrics like Chunya fabric, they can significantly reduce the weight of luggage. For instance, a standard-sized carry-on bag made with Chunya fabric and TPU composite fabric can be reduced in weight by about 300 grams, enhancing carrying comfort, reducing physical exertion during travel, and facilitating transportation while also reducing carbon emissions.
Durability
High Strength: TPU films have high tensile strength and tear resistance. When combined with fabrics, they enhance the overall tensile and tear resistance. Experiments show that the tensile strength of Chunya fabric and TPU composite fabric can reach over 30N/cm, and the tear strength exceeds 8N/cm, which is more than twice that of ordinary polyester fabrics.
Abrasion Resistance: The abrasion index of TPU films can reach 1.5-2.5, far higher than the 0.5-1.0 of ordinary PVC materials. This ensures that the surface of luggage remains smooth and undamaged even under frequent friction, extending its service life.
Chemical Resistance: TPU films are chemically inert and can resist common chemical substances such as acids, alkalis, oils, and detergents, preventing issues like discoloration and aging of luggage.
UV Resistance: TPU layers contain special UV stabilizers that can effectively absorb and reflect ultraviolet radiation, preventing material degradation or brittleness due to sunlight exposure and maintaining stable performance.
Waterproof and Breathable: TPU films have excellent waterproof properties, effectively preventing water penetration. They also have a certain degree of breathability, ensuring the interior of luggage remains dry even during prolonged use or in adverse weather conditions.
Flexibility: TPU films are soft and elastic, allowing luggage to better return to its original shape when compressed or bumped, providing good cushioning and protection for internal items. They also increase the flexibility of luggage design, enabling more unique shapes and structures.
Appearance and Design Advantages
High Transparency: TPU films can be made transparent or semi-transparent, adding a modern and unique touch to luggage. They can be used to create transparent windows, decorative strips, and other parts of luggage, enhancing the design’s depth and visual appeal.
Rich Colors: Various bright and long-lasting colors can be achieved by adding color masterbatches or through surface printing and coating processes, meeting the personalized color demands of different consumers for luggage appearance. They can also simulate the textures and qualities of different materials like leather and fabric, enhancing the aesthetic appeal and quality of luggage.
Good Processing Performance: TPU films are easy to process through techniques such as heat forming, welding, and laminating. They can be combined with various materials like fabrics, leather, and plastic to create diverse composite fabrics, providing more creative space for luggage designers and enabling complex design details and functional integration.
Environmental Advantages: TPU films are environmentally friendly materials, non-toxic and odorless, and recyclable. When buried in soil, they can naturally decompose within 3-5 years under the influence of moisture and microorganisms, aligning with modern consumers’ pursuit of sustainability and the environmental development trend in the luggage industry.
