 Higher quality corrugated cartons are converted by means of preprint roll, medium and bottom liner on the corrugator. The outer liner is printed roll to roll, sent to corrugators for corrugating into carton boards, and further converted into carton boxes in the latter process of die cutting. Carton boxes manufactured through this process meet not only the fine printing requirement but also better physical property which is 30% more than offset printed carton box with the same materials. The production cost is also significantly lower. Meanwhile, we can design and produce nonstandard novel structure corrugated carton box according to customer’s requirement.
