Clamshell boxes for phone cases and tech accessories
Phone cases, chargers, cables, stands and power banks share a retail pattern: a slim, high-value item that a customer wants to see, in a box that a carrier will not treat gently. HESHENG (CSL) molds fiber clamshell packaging for tech accessories - a two-part enclosure that protects the product, holds its accessories in defined wells, and gives it a plastic-free unboxing moment.
Design points specific to phone accessories:
- Snug cavity tolerances - cases and power banks are molded to sub-millimetre dimensions, so the cavity is built from your actual part file rather than a nominal size.
- Cable channeling - a molded figure-eight route so a coiled cable stays coiled instead of springing loose in the box.
- Screen-safe contact - where a display unit is shipped, contact points are kept off the glass area.
- Tamper-evident tab - a molded tab that breaks visibly on first open for returns-heavy channels.
- Hang tab or shelf-ready format - molded hole for peg display, or a base geometry that stands on a flat shelf.
Fiber clamshells replace the rigid plastic box-and-tray combination that most accessory brands currently use, with a single material that goes straight into the paper recycling stream. For brands shipping electronics, fiber also avoids the static issues that make bare foam risky near circuit boards.
MOQ 10,000 pieces per design; tooling 7–15 days; production 15–25 days after sample approval. Send your product dimensions or 3D file and we will confirm the cavity fit with a prototype: request a tech accessory packaging quote.
