Product packaging specification
Packing of module products
Put the qualified products into the corresponding model blister box packaging.
The bottom, surface and side of the carton are filled with one piece of anti-static foam to protect the product.According to the requirements of the packing quantity, put the blister box box of the product into the packaging carton. If the space between the blister boxes is large, use a piece of anti-static foam to put it in the middle. The empty space in the end box must be filled with anti-static foam to ensure that it will not be damaged during transportation.
The outer case label is attached to the side position of the outer case,Label the outer case after sealing.
At the time of delivery, the entire outer box should be wrapped with at least 2 layers of wrapping film protection.
