Description

Packaging box with transparent isolation display area and forming method thereof Technical Field The invention relates to a packaging box with a transparent isolation display area and a forming method thereof, belonging to the technical field of product packaging. Background The packaging box has the functions of product protection, visual display and brand image improvement, and is an important carrier for the product circulation link. According to product positioning, cost budget and texture requirements in the current industry, the transparent display packaging box is divided into three layers, each layer corresponds to a special base material and a processing technology, wherein the low-end packaging is made of common corrugated paper as a main material, the middle-end packaging and high-end packaging is made of a solid packaging plate as a core base material, and the high-end luxury packaging is formed by processing metal materials. The packing box with the transparent display area can realize visual display of internal products, is widely applied to industries such as cosmetic, digital, literature, gifts and the like, and is a main stream form of medium-high-end packing. The common corrugated paper has low cost but insufficient structural strength, is only suitable for temporary packaging of simple and low-value products, has poor durability and aesthetic degree, and the transparent area of the common corrugated paper is generally in a simple attaching mode, so that the firmness and the aesthetic degree are poor. The solid pressed package is a solid compacted hard paperboard, has stiff and smooth material and strong deformation resistance, is a preferred base material of a middle-high-end gift box, but has a rough processing technology in the existing transparent area, and the metal package is processed by adopting a metal laminate, and is fixed by riveting and embedding, so that the solid pressed package has high quality, strong firmness, high raw material and processing cost and difficult large-scale popularization. The packing boxes of the corrugated paper and the solid pressing plate are paper structures, the transparent layers of the packing boxes are adhered to the paper plates only by means of glue monolayers, the problems of degumming, edge warping and displacement easily occur after long-term storage or transportation jolt, and the inner-adhered structure is extremely easy to collapse and deform due to lack of effective support, so that the packing integrity is damaged, and internal products are knocked and scratched. The edge of the externally attached transparent layer is exposed, the problems of glue overflow, burrs, uneven splicing and the like frequently occur, the process roughness is obvious, the texture of the middle-high end real-pressure packaging plate is superior, the overall grade is greatly reduced by matching with the simple attached transparent layer, and the low-cost sense is outstanding. The transparent layer is easy to deform after being extruded by external force, the probability of breakage of the transparent layer is higher, the transportation safety of products cannot be guaranteed, the riveting embedding process of metal packaging is high in quality but high in cost, and the middle-high-end solid pressing packaging plate is not provided with a matched high-quality transparent layer fixing process, so that the texture, the firmness and the cost control cannot be considered. Disclosure of Invention The invention aims to solve the defects in the prior art, and provides a packaging box with a transparent isolation display area and a forming method thereof, aiming at the problems of poor lamination firmness, poor attractiveness, outstanding cheap sense, easy turnover transportation and the like of a traditional paper packaging box. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The packaging box with the transparent isolation display area comprises a box body and a transparent layer, wherein the box body is formed by adopting a real-pressure packaging plate; At least one forming wall of the box body is provided with a hollowed-out window for carrying the transparent layer, a bearing locking part is pressed on the periphery of the hollowed-out window, the bearing locking part comprises an annular groove and a supporting step, the annular groove is positioned on one side, away from the hollowed-out window, of the supporting step, and the annular groove faces to the outer side of the box body; the transparent layer comprises a transparent area which is matched with the hollowed-out window in a profiling way, the periphery of the transparent area is provided with a composite outer edge, and the composite outer edge comprises a fitting edge which is used for being fitted with the supporting step and a peripheral bending edge which is used for being embedded into the annular groove; The composite outer edge is bonded and compou
