Description

Packing box

[ technical field ] A method for producing a semiconductor device

The invention belongs to the technical field of packaging, and particularly relates to a packaging box.

[ background of the invention ]

In the milk product packaging technology, the products are wrapped in cartons, such as common tetra Pak type products in a 4 x 6 matrix arrangement form and yogurt cup type products in a 2 x 6 matrix arrangement form, and the packaging forms of the products have the common characteristic that the products are wrapped in cartons after being regularly arranged. The products wrapped with the carton can meet wide market demands in the retail field, and compared with individual products, the large products formed by the carton-wrapped products can meet long-term stable use demands, such as demands in a home environment. The packaging form of the large products is a cube or cuboid structure, and the packaging structure has no striking characteristics; the use mode of a single product cannot be close to the use requirement in a household environment. Therefore, consumers are more likely to use the products in a home environment or to give the products as gifts by chance when selecting large products, and more likely to meet the current use requirements, such as breakfast after temporary purchase while out, if selecting a single product.

With the change of people going out and the abundant and varied characteristics of social occasions, the single demand for milk products tends to be a medium-weight state, i.e. the quantity of the milk products purchased at a time is not single but far less than that of large products, for example, 6 to 8 bottles of milk products are purchased by relatives and friends in outing. Obviously, to obtain this quantity of milk products, one product to be sold in a single body is taken one by one, and only from the whole box of milk products; either way, the use requirement cannot be well met, and after all, a process of carrying about exists before the milk product is eaten.
