Description

Technical Field

[0001] The utility model relates to packaging technology, in particular to a combined packaging box for packaging multi-unit and multi-layer superimposed products. Background Art

[0002] In the prior art, small products are generally packed in a large packaging box. This type of packaging box is made of a combination of various plastic inner cushioning pads and cartons. The inner cushioning pads can generally be made of EPE, EPS, EPP and other materials. Although the cushioning protection effect is relatively good, the overall packaging cost is high due to the high unit price of the material. In addition, the EPE material is soft, the cushioning packaging space is large, and the transportation cost is relatively high. The use of corrugated cardboard cushioning pads is low-carbon and environmentally friendly, with low costs. At the same time, the cardboard space in the box is assembled into a product size space structure and the left and right cardboard spaces are divided into multiple accessory storage areas. The inner cardboard is a connected packaging that can better meet the packaging needs of integrated products. That is, all the products can be placed in the inner packaging paper card and then placed in the packaging. There are multiple hand holes designed inside, which is very convenient for extracting the entire set of inner paper card products. It saves costs and greatly improves production efficiency. The inner cardboard can also be reused as a load-bearing paper pallet. During the design process of the inner paper card, factors such as good compressive strength in the direction of the paper and large area are taken into consideration to make it more reusable. The cardboards on both sides of the inner cardboard are reduced in size to match the size of the forklift arm. The load-bearing compressive strength can be calculated based on the gram weight of the paper and the weight of the related products to be stacked.

[0003] With the increasingly fierce market competition, manufacturers are gradually tightening their control over costs. The cost of packaging and logistics transportation costs have become indispensable assessment factors. Therefore, the reduction of packaging materials, simplification of processing, and convenience of use have become the main directions of packaging technology research. The many shortcomings of the existing packaging methods on the market have brought some adverse effects to manufacturers and users. Therefore, it is necessary to study a new packaging technology that changes and improves the current situation. In addition, this packaging product can be completely recycled and reused, which is completely in line with the environmental protection environment. Summary of the invention
