6. Install the box corner

Install 4 box corners on the four corners of the bonded box body. This box corner is also made of PP plastic particle injection. The function is to cover the hairline at the intersection of the long edge strip of 5mm clearance and the wide edge strip of 10mm clearance. More importantly, it is used to strengthen the load bearing capacity around the box body and fix the position of the upper box when stacking so that the container with good stacking code is not only orderly but also immovable.
