Precise clearance around vulnerable product features (e.g., displays, buttons, glass edges).
02
Multi-Component Alignment
Secure placement for accessories, cables, and power adapters.
03
In-Tray Stability
Prevention of product movement or migration during handling.
04
Outer Packaging Fit

05
Visual and Surface Defect Criteria
Critical Defects
Structural cracks, pinholes, incomplete forming, or thin spots.
Edge & Surface Quality
Absence of burrs, excessive flash, loose fibers, or dust contamination.
Contamination Control
Zero oil spots, chemical residues, or foreign particle inclusions.
Finish Type
Smooth, high-density finish for thermoformed (wet-press) trays versus natural texture for standard dry-press trays.
