Screen protector 3MK FlexibleGlass for SUNMI V3 (model V3) — flexible tempered protective film

3MK FlexibleGlass for SUNMI V3 is a flexible tempered protective film designed specifically for the SUNMI V3 terminal. The protector combines the flexibility of polymer films with the surface hardness of tempered glass to resist scratches and everyday wear while preserving the device’s touch responsiveness and display clarity. It is intended for daily protection in retail, hospitality and mobile point-of-sale environments where screens are subject to frequent use and occasional minor impacts.

Advantages

The FlexibleGlass construction offers a balance between impact absorption and surface hardness, reducing the risk of visible scratches and minor cracks while maintaining smooth touch operation. The protector is optically clear to preserve display colors and contrast, and its adhesive layer provides bubble-free installation and reliable adhesion to the SUNMI V3 touchscreen. The thin profile maintains compatibility with cases and accessories commonly used with mobile POS terminals.

Suitable for

• Retail checkout terminals and handheld POS devices
• Hospitality environments such as restaurants and bars
• Field sales and mobile payment terminals
• Environments where frequent touch interaction requires preserved sensitivity

When it may not be suitable

This protector is designed for protection against scratches, minor impacts and surface wear rather than heavy impact resistance. It may not prevent damage from severe drops or concentrated blunt force. If the SUNMI V3 will be regularly exposed to extreme mechanical stress, reinforced glass solutions or additional casing may be more appropriate.

Key specifications

• Material: flexible tempered protective film combining polymer flexibility with a hard surface layer
• Compatibility: designed for the SUNMI V3 touchscreen
• Thickness: thin profile to retain touch sensitivity and case compatibility
• Optical clarity: high transparency to maintain display color and contrast
• Surface protection: scratch-resistant surface layer
• Adhesive: permanent optical adhesive for bubble-free application

How to use

Clean the SUNMI V3 screen thoroughly with a lint-free cloth and any included cleaning wipe to remove dust and oils. Align the protector with the device edges and camera/opening cutouts, then lower it onto the screen from one edge to minimize trapped air. Press gently from the center toward the edges to secure adhesion and remove any remaining bubbles. If necessary, lift and reapply carefully to correct alignment, ensuring the adhesive side remains clean during handling.

What to consider before purchase

• Verify compatibility specifically for the SUNMI V3 model to ensure correct fit and cutouts
• Assess the level of mechanical protection required—FlexibleGlass is optimized for scratch and surface protection
• Consider if additional casing or reinforced protection is needed for heavy-impact environments
• Check if the package includes installation accessories and cleaning materials for best results

Usage recommendations

For optimal performance, apply the protector in a dust-free environment and allow adhesive to settle for 24 hours before heavy use. Clean the surface with a soft, lint-free cloth and avoid abrasive cleaners. Replace the protector if deep scratches or peeling occur to maintain screen protection and touch accuracy.
