Packaging & Transportation Storage Requirements:

1. Packaging Requirements:
   TRSM-2 artificial graphite should first be packed into 650mm×950mm plastic bags, sealed, and then placed in a cardboard box. The weight is 25 + 0.02kg/box, or packaged according to user requirements.
2. Transportation and Storage:

a. The product should be stored in a dry, ventilated place free from other sources of pollution (recommended: temperature ≤45℃, humidity ≤85%);
b. The product should be stacked neatly and cleanly, and the production batch number, production date, and other markings should be clearly identifiable;

c. Handle with care during transportation to avoid damaging the packaging; any product that spills out of the packaging must not be returned to the box.

d. Shelf life is 2 years at room temperature.
