Normal > A company in the United Kingdom has also developed a new thin cardboard box for food, office paper and other packaging. This thin cardboard box is divided into two separate upper and lower parts. The lower part accounts for about 1/3 of the height of the entire cartons . There are two handles on both sides. The upper part is a square paper shell with the same height as the whole package. By covering the shell on the carton, it becomes a complete package box. When used, carry it through the handle at the bottom, and the contents will not be tilted or fallen.
