The reason why:
If you tape it, almost every time the person who receives it will blade open your box. There is a large percentage of possibilities that it will cut into the box and damage your goods and box itself.
The use of optional closures that do not require a blade to open the box, it will avoid unnecessary damage and extend the service life of your reusable containers.
Most customers use corrugated plastic products because they are durable and reusable, or corrugated paper products can't do the job properly in some circumstances. Apart from that, not many customer pays extra for one-time use. So the last thing you want, is someone damage it with a blade when he try to open the box.
