When I work in my previous company, our company has complained by our big customer because of the corrupted of carton boxes after the shipping. I think my company should invest some money to order custom cardboard boxes because they are more durable. The weight of our products are heavy, it is about 50kgs for 1 box, this is why we need custom cardboard boxes. I was thinking my boss will not going to consider this type of box because it will be slightly costly than our current box that we are using. Anyway, for those people who are looking for custom cardboard boxes, perhaps you can check out packnboxnow.com today!
