1. Core Structure of the Rigid Lid & Base Box
The rigid lid & base box is a two-piece rigid packaging system consisting of a separate top lid and a bottom base. It can be equipped with custom inserts, liners, or trays to secure and protect products during shipping and display.
Following modular and precision-engineered production standards, its structure ensures consistent quality and efficient mass production.
1.1 Key Components & Material Specifications
| Component | Material | Function |
|---|---|---|
| Bottom Base | 1.38mm thick rigid grey board | Forms the main structure and supports products and inner liners |
| Top Lid | 1.38mm thick rigid grey board | Covers the base, enhances branding, and creates a premium unboxing experience |
| Inner Liner / Insert | 12mm high-density sponge, EVA, velvet, or foam | Cushions products, prevents scratches, and fixes items in place |
| Outer Wrapping Paper | Coated paper, specialty paper, matte or glossy art paper | Supports custom printing, hot stamping, embossing, and lamination |
1.2 Production & Assembly Process
Base Forming: Rigid board is cut to size, wrapped with selected paper, and shaped into a stable tray-style base.
Liner Installation: A 12mm custom die-cut liner is placed inside the base to hold products securely.
Lid Making: The lid is produced slightly larger than the base for a smooth, tight fit, then wrapped and finished.
Final Assembly & Finishing: The lid is fitted to the base, followed by brand printing, hot stamping, UV coating, or other surface treatments as required.
