4 Packaging
4.1 General rule
4.1.1 The packaging of the product shall prevent it from getting damp and contaminated
during transportation and storage.
4.1.2 Products in the same box, bag, can or bottle shall be from the same batch. In
special cases, when products from different batches are packed in the same box, they
shall be packed in separate bags/cans/bottles and marked with product brand, batch

packaging method shall be implemented in accordance with the product standards or
order forms.
4.2 Inner packaging
4.2.1 General rule
4.2.1.1 For products with a particle size less than 53 μm, packaging should be carried
out in an inert gas atmosphere, such as an argon-filled glove box.
4.2.1.2 Products with a particle size of not less than 53 μm may be packaged in an
atmospheric environment. In special cases, such as products with high sensitivity to O,
N, H2O, etc., packaging should be carried out in an inert gas atmosphere.
4.2.2 Packaging bags
4.2.2.1 When packaging bags are used for packaging, double-layer vacuum packaging
shall be used and there shall be no air leakage after packaging. See Figure 1 for a
schematic diagram and design sketch of the product packaging.
4.2.2.2 When products are packaged in plastic bags, the bags shall comply with the
requirements of GB/T 10004, and the packaging quantity shall match the load-bearing
capacity of the bags.
e) Net weight.
5.2 Outer packaging mark
Each product packaging box shall have an independent box tag or label, which shall
indicate:
a) Product brand;
b) Specifications;
c) Batch number;
d) Net weight;
e) Box number.
5.3 Transport mark
The transportation mark of the product shall comply with the provisions of GB/T 6388.
