Key control points for the production of customized eyeshadow boxes

In the field of precision manufacturing of beauty packaging, customized eyeshadow boxes must simultaneously meet the triple standards of aesthetic design, functional adaptation and production feasibility. This specification is based on the latest industry standard (ISO 22716:2025) in 2025 and the process parameters of leading OEM manufacturers, and extracts 7 core considerations:

1. Structural design parameters

Opening angle: The magnetic box body recommends a golden opening angle of 135°-150° to ensure the stability of one-handed operation (force value ≤0.8N)

Inner lining thickness: The sponge buffer layer must reach 3mm±0.2mm, and the breakage rate of the drop test (1.5m/6 faces) must be <0.3%

2. Material selection

Environmental certification: PETG material with a PCR content of ≥30% is preferred, in compliance with Annex XVII of the EU REACH Regulation

Surface treatment: The UV coating hardness must reach 3H, and the haze change after 500 times of the wear test (Taber CS-17) is <5%

3. Production supervision

Color difference control: Pantone spot color printing ΔE value must be ≤1.5, and spectrophotometer is used for daily calibration

Assembly tolerance: The concentricity deviation of the magnetic suction component is ≤0.05mm, and high-precision CCD detection equipment is required

4. Special process

Hot stamping process: The heat resistance of electroplated aluminum must reach 180℃/30s without falling off, and the adhesion test (grid method) is 4B or above

Relief effect: The mold engraving depth is recommended to be 0.3-0.5mm. Too deep will easily lead to injection molding defects
