Quality inspection requirements for cardboard boxes

·Sealing quality: There are no leaks around the box, and there are no gaps or seams after the closure of each box cover

There is a seam after sealing, which cannot be closed

·Dimensional tolerance: The tolerance between the inner diameter of the box and the design dimensions on the drawing should be maintained at ± 5mm, and for small boxes, it should be ± 3mm. 

The overall dimensions should be basically the same to avoid the actual size being too small and unable to package the product normally;
