When we first see the iron box, we will have an objective judgment on the box. The first thing we see is the surface of the iron box. The information reflected on the box surface, such as patterns, printing, barcodes, models and specifications, is not randomly placed. It has certain rules. The randomly printed iron box is already unqualified on the surface. Again, check the box surface for scratches, and the printed surface shall not be greater than 0.3mm * 20mm. On the front side, the pattern of the product surface is placed directly in front of and below the sunlight. In addition to the main viewing surface of the box, you can also see the inner surface, side, bottom, etc.
The above are the tips that can manufacturers share with you on how to judge whether boxes are standard. Have you learned?
