A good carton box is a combination of all the above mentioned factors and of course not to forget the paper weight of the liner used to produce the liners (standard paper 125gsm). A thick carton box does not necessary mean that it is good. It has to be a combination of a good external, internal liner and a optimal paper weight of at least 125gsm (A heavier paper weight is used for moving boxes usually can be up to 300gsm)Last but not least, know what you are using it for and how are you using it.
