Need some help regarding corrugated cardboard

I don’t know what kind of laser you have access to, but sometimes it leaves a scorched edge on cardboard… I prototyped some packaging on a friends machine and it was a noticable discoloration.

Another idea, rather than glue, design in a jig (like mentioned earlier) - especially if you laser cut.The advantage is that it might be easier than tedious gluing and more recyclable (which might be a good aspect for your review)
