Storage & Transportation Instructions
Professional warning marks are printed on product packages to ensure stable product quality through standardized operation:
Moisture Proof: This powder material is highly hygroscopic and prone to caking. It must be stored and transported in a dry and ventilated environment. Moisture should be strictly avoided to prevent performance degradation and caking that affect processing effects.
Hook Forbidden: Hand hooks are prohibited during handling, loading, unloading and transportation. Hook scratching will cause package damage, resulting in powder leakage, material loss and raw material contamination.
Adopting 25kg professional moisture-proof sealed packaging, standardized storage and transportation can effectively maintain the original fluidity and stable performance of the PVC powder.
