Modern merchandise extends far beyond simple pin badges, and our Flat Medium-Sand Back Cover is specifically engineered to cater to the growing market of adhesive-backed accessories, pocket mirrors, and phone grips. Unlike traditional curved or pinned backings, this Flat Medium-Sand Back Cover features a completely flat profile combined with a premium medium-sand textured finish. This flat design provides the perfect, level surface area for applying double-sided adhesive tapes, magnetic sheets, or suction cups, ensuring a solid, gap-free bond that will not peel off under tension. Produced in our 1,800-square-meter state-of-the-art facility, we utilize precision flat-stamping molds on our high-speed punching machines to guarantee absolute flatness across the entire backing surface, with zero warping or edge raising. The medium-sand finish adds a sophisticated matte texture that not only hides minor surface scratches but also enhances adhesive adhesion by providing a micro-textured surface area. For B2B buyers, gift wholesalers, and DIY accessory brands, our flat backing provides the ultimate structural canvas to expand your product lines into premium phone sockets, compact mirrors, and creative stationery items.
Direct sourcing from our factory provides your business with an unbeatable supply chain advantage, backed by our monthly production capacity of 100 million PCS.

FAQ
Q: How does the flatness tolerance affect the adhesion of double-sided tapes?
A: If a backing is even slightly curved, the adhesive tape will lift at the edges over time. Our strict ±0.05mm flatness tolerance ensures 100% surface contact, creating a permanent, gap-free bond.
Q: Can you apply a custom adhesive tape layer directly to the backings at your factory?
A: Yes. We can pre-apply high-strength custom double-sided adhesive liners or magnetic tape. Our R&D team can develop the exact assembly prototype within 25 to 35 working days.
Q: Is it possible to combine standard flat backings and customized flat sizes in one shipment?
A: Yes. We support mixing standard and custom flat sizes within our flexible MOQ guidelines to help you expand your product lines efficiently.
