Improper storage conditions cause raw material performance decline
Problem Phenomenon
Improper storage conditions cause raw material performance decline
Cause Analysis
Storage environment humidity too high, cellulose acetate butyrate absorbs moisture and performance declines
Storage temperature too high, partial raw material degradation
Storage time too long, additives fail
Packaging damaged, raw material contaminated
Not managed first-in-first-out, inventory backlog and aging
Solution
Control storage environment humidity ≤60%RH
Storage temperature ≤30°C
Set raw material shelf life management
Check packaging integrity
First-in-first-out inventory management
Key Takeaway
Raw material storage requires humidity and temperature control
