Material Introduction
WINIW, a leader in synthetic leather innovation, presents its tensile strength synthetic leather specifically engineered for PU leather cases. This product addresses the critical need for resilience in case manufacturing, as cases—whether for electronics, tools, or accessories—must withstand stretching and pressure without deformation. WINIW’s deep understanding of material performance ensures this synthetic leather balances superior tensile strength with practicality.
The synthetic leather undergoes a proprietary reinforcement process that enhances its ability to resist stretching, even when cases are expanded to fit items or subjected to external pressure. It maintains a thin, lightweight profile, avoiding the bulk that can make cases cumbersome to carry or store. Unlike rigid materials, it retains flexibility, allowing cases to bend slightly for easy use while staying structured.
WINIW’s tensile strength synthetic leather for PU leather cases caters to a wide range of industries, from consumer electronics to tool manufacturing. It accepts custom cuts and finishes, supporting diverse case designs—from sleek phone cases to rugged tool organizers. Every piece reflects WINIW’s commitment to quality, undergoing rigorous testing to ensure consistent tensile performance. As a trusted supplier, WINIW delivers a material that elevates case durability and functionality, meeting the needs of both manufacturers and end-users.


Material Feature
Superior Tensile Strength Against Deformation
The synthetic leather features a reinforced fiber structure that provides exceptional tensile strength. It resists stretching when cases hold large items or endure pressure, ensuring the case retains its original shape and fit over time, avoiding sagging or distortion.
Lightweight & Flexible for Practical Use
Unlike rigid high-strength materials, it remains lightweight and flexible. This makes cases easy to carry, store, and handle—essential for portable items like electronic cases or travel organizers. The flexibility also allows for easy access to case contents.
Durable Surface & Easy Construction
Its surface resists scratches, scuffs, and minor abrasions, maintaining the case’s appearance. It bonds securely with linings, zippers, and closures during manufacturing, ensuring sturdy construction. It also adapts to printing and cutting, supporting custom designs and precise sizing.


Application Scenarios
Electronic Device Case Production
Perfect for crafting phone, tablet, or laptop cases. Its tensile strength prevents stretching from device insertion/removal, while lightweight flexibility ensures portability. The scratch-resistant surface protects both the case and device, meeting consumer demands for durability.
Tool & Hardware Case Manufacturing
Ideal for tool cases holding wrenches, drills, or hardware. Its tensile strength resists stretching from heavy tools, and the durable surface withstands workshop wear. The flexibility allows the case to open fully for easy tool access.
Travel Accessory Case Creation
Suitable for travel cases like toiletry bags or jewelry organizers. Its lightweight nature keeps luggage weight down, while tensile strength prevents sagging when filled. Moisture resistance protects contents from travel humidity.
Industrial Equipment Case Design
Perfect for cases housing small industrial equipment or measuring tools. Its high tensile strength withstands industrial environments, and easy processability allows for custom cuts to fit specific equipment. The sturdy construction ensures equipment safety during transport.
