The Medium-Sand Laminated Button Back is a backplate component specifically designed for small- to medium-sized badges that require superior protection and refined detailing. Building on the robust structure and distinctive tactile feel of the classic grit back cover, it incorporates an innovative, high-performance transparent protective coating (lamination) on the outer surface.
Medium-Sand Laminated Button Back coating fully preserves the delicate matte texture of the grit finish while forming a strong, smooth physical barrier. As a result, it delivers a comprehensive upgrade in scratch resistance, fingerprint resistance, corrosion resistance, and overall visual quality. This product represents the integration of protection, tactile comfort, and aesthetics in a premium metal back cover, making it particularly suitable for high-end badges that require frequent handling, long-term preservation, or use as refined gifts.
Core Materials and Processes
Substrate and Texture
Manufactured from a high-quality metal substrate, the surface is formed with a uniform, moderately textured matte finish through a standard medium sanding process. This provides an excellent tactile feel along with reliable structural strength.
Lamination Process
A high-transparency polyester (PET) protective film is precisely laminated onto the textured surface. This process requires exceptional precision to ensure that the film fully covers the texture without bubbles or orange-peel effects, and that it bonds securely to the metal substrate without affecting the original dimensions or fastening function of the back cover.
Functional Integration
The "medium sand" texture provides a non-slip feel and an excellent base for ink adhesion, facilitating screen printing when required. The protective coating layer is responsible for resisting external physical and chemical damage. The combination of these two elements achieves a synergistic protective effect, where 1 + 1 > 2.

Core Product Advantages
A groundbreaking dual-protection system:
The internal metal structure provides strong, pressure-resistant support, while the external coating protects against scratches and corrosion. Together, they deliver comprehensive, inside-out protection for small, finely crafted badges and significantly extend product lifespan.
A perfect balance between tactile feel and easy maintenance:
The surface retains the non-slip texture of the sand finish, while the smooth laminated layer makes cleaning effortless. Fingerprints, oil stains, and water marks can be removed with a single wipe, effectively solving the common issue of traditional frosted surfaces being difficult to clean.
Significant enhancement of visual appeal and consistency:
The protective film adds a subtle, refined sheen to the surface, making colors appear more uniform and vibrant while elevating the overall craftsmanship. High consistency across production batches reflects a premium level of quality.
Improved resistance to environmental aging:
The coating effectively isolates the underlying metal from moisture and salts in daily perspiration, preventing oxidation, whitening, or rust formation. This makes the product especially suitable for humid environments or frequent hand contact.
An ideal base for value-added processing:
The flat, stable coated surface provides an excellent foundation for fine screen printing or laser engraving. Printed elements are sharp and durable, making it ideal for adding brand logos or unique serial numbers.
Typical Application Scenarios
High-end miniature badges and accessories
Used for premium small-format anime character badges, jewelry-grade brooches, or collar ornaments, providing refined protection consistent with their upscale positioning.
Collectible badge series
For limited-edition or commemorative badges, the back cover offers protection equivalent to the front, ensuring long-term preservation of collectible value.
Frequently used gifts and promotional items
As premium business or membership gifts, the excellent tactile feel and easy-clean surface deliver a quality experience with every touch.
Applications with hygiene requirements
Ideal for catering industry promotional badges or themed event souvenirs, where the smooth, stain-resistant surface simplifies cleaning and disinfection.
