Seasonal brands warehouse trays for months, then wonder why cavities warped. Storage is part of mold life. RUUIPON ships custom silicone molds at MOQ 50 with packing that nested trays survive freight - storage after arrival is on you.
Quick answer: Cool, dry, dark; no direct sun; no ozone from motors; nest without crushing webs; clean before long storage.
Storage Do / Do Not
| Do | Do not |
|---|---|
| Clean and dry fully | Store wet / sugary residue |
| Nest with supports | Point-load heavy boxes on trays |
| Away from UV | Window sills |
| Away from ozone sources | Beside motors / welders |
Environment
Cleaning: cleaning and storage. Warp prevention: warping prevention.
Stacking
Nesting design: tray nesting. Shipping damage signs: shipping inspection.
Ozone and UV
