Packaging and storage

1. The product is packed with impervious aluminum foil/polyethylene composite film bag, which usually has a net weight of 25kg and is packed into a single unit, and is transported by single pallet palletizing. The net weight specifications of single pallet palletizing are 1000kg, 1250kg and 1500kg.

2. Should be stored in a clean, dry and ventilated environment, suitable for storage temperature 0℃ ~ 35℃.

3. The validity period of the package is 6 months in the closed state, and it is recommended to use within 24 hours after opening. If the recommended time limit is exceeded, the quality of use will be affected by pre-crosslinking.
