When cutting notches on the inner tray of jewelry ring packaging to secure the ring, many jewelry box design merchants consider how deep the notches should be. In fact, the choice of notch depth in jewelry packaging boxes needs to take into account the following factors:
1.Recommended Depth Range for Jewelry Ring Packaging:
(1) General Recommendation: The cut depth should be 1/2 to 2/3 of the ring’s thickness (e.g., if the ring thickness is 2mm, the cut depth should be approximately 1~1.3mm).
(2) Material Limitation: The cut depth should not exceed 50%~70% of the inner cardboard thickness (e.g., if the cardboard is 2mm thick, the cut depth should not exceed 1~1.4mm) to retain sufficient support strength.
2.Key Considerations for Jewelry Ring Packaging
(1) Ring Characteristics:
Minimalist Design (1~1.5mm thickness): Cut depth 0.5~1mm.
Inlaid Design (2~3mm thickness): Cut depth 1~2mm (adjust according to cardboard thickness).
(2) Cardboard Strength:
Thin Cardboard (1.5~2mm): Cut depth should not exceed 1mm to avoid penetration.
Thick Cardboard (3mm+): Can be cut to 1.5~2mm, but load-bearing capacity must be tested.
(3) Functional Requirements:
Display Purpose: Slightly shallow cut (e.g., 0.8mm) for easy access and placement.
Transportation Purpose: Slightly deeper cut (e.g., 1.2mm) to enhance stability.
By balancing stability and structural strength, the depth of the incisions in the jewelry ring packaging insert can be rationally designed to ensure the ring remains secure and stable during display or transportation. It is recommended to prioritize the creation of prototypes for testing and optimization.
