This small accessory we touch countless times a day has evolved into a key consumable that blends fast-fashion with personal expression. With a vast array of phone case options available, decision fatigue has become a common dilemma. Today, we’ll explore three cost-effective phone case categories, uncovering the unique performance and charm behind their distinct materials.
Prosub Technology – Sublimation 2D Film Case
Prosub’s sublimation 2D film case is crafted from PBT (polybutylene terephthalate), a high-performance engineering plastic. Renowned for its ease of coloring, no-coating requirement, and affordability, PBT is widely used in the phone case industry.
Four Core Advantages of Our Sublimation 2D Film Case
Exceptional Stain Resistance – Stay Grease-Free: The PBT material boasts ultra-low moisture absorption and strong oil resistance, ensuring a fresh touch and clean appearance even with long-term use.
Eco-Friendly & Non-Yellowing: Made from high-quality virgin PBT pellets, our case is non-toxic, odorless, and environmentally friendly. Its excellent UV resistance effectively prevents yellowing caused by prolonged sunlight exposure.
Vivid Printing & Premium Texture: Featuring a smooth, dry texture and stable coloration, the case delivers sharp, lifelike prints through sublimation transfer, achieving seamless integration of design and casing.
Prosub Technology – 2-in-1 Film Case
Building on the sublimation 2D film case, our 2-in-1 version adds an inner TPU soft shell, forming a protective structure of “outer PBT hard shell + inner TPU soft shell”. The outer hard shell resists impacts, while the inner soft shell provides snug wrapping, creating a reliable dual-protection system.
Advantages of Our 2-in-1 Film Case
Combined Durability & Shock Absorption: The rigid backplate offers strong support and scratch resistance, preventing phone bending from external forces. The inner soft layer enhances shock absorption, delivering comprehensive protection.
Easy Installation & Precise Button Response: The elastic TPU inner shell minimizes scratches on the phone frame during installation and removal. Buttons are accurately aligned, ensuring crisp, responsive feedback.
Long-Lasting Color & Stylish Layered Look: The PBT shell maintains vibrant prints over time. The “hard-on-soft” structure adds a sense of design and depth, appearing thicker and more refined than single-material cases.
Prosub Technology – Sublimation TPU Coated Case
Crafted from thermoplastic polyurethane (TPU), this case strikes a balance between flexibility and rigidity – not as soft as silicone nor as hard as rigid PC. As one of the most popular phone case types on the market, it perfectly combines protection, comfort, and minimalism.
Advantages of Sublimation TPU Coated Case
Showcase Phone’s Original Beauty: Transparent TPU cases protect the phone while fully displaying its original color and texture, ideal for users who appreciate understated minimalism.
Slim Fit & Versatile Design: Basic transparent blanks are ultra-slim and form-fitting, without adding extra weight or bulk. TPU’s ease of processing allows for complex prints and color effects.
Highly Cost-Effective: With widespread availability of TPU materials and mature production processes, these cases are affordably priced, offering exceptional value for money.
Superior Drop Protection: TPU’s elastic properties provide excellent shock absorption, safeguarding the phone’s frame and back panel, and reducing the risk of screen and internal component damage.
Conclusion
All three case types support full-area printing for flawless image presentation. There is no hierarchy of quality or protection – each excels in its own way in terms of defensive technology and personalized aesthetics. Choose your perfect accessory based on your desired protection level and printing needs.
