Description

Waterproof and pressure-resistant packing carton

technical field

The utility model relates to the field of packaging, in particular to a waterproof and pressure-resistant packaging carton. the

Background technique

Because the cost of paper packaging materials is low and can be recycled and recycled, most of the existing packaging materials are made of cardboard, but the packaging cardboard is not waterproof, and it is easy to deform after being damp, which affects the quality of the items in the package. At the same time, The packaging cardboard itself is weak in strength, and it is often squeezed and deformed during transportation, which also affects the quality of the items in the package. the

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a waterproof packing cardboard. the

In order to achieve the above object, the utility model adopts the following technical scheme to realize:

Waterproof and pressure-resistant packaging cartons, including a top cover, a bottom plate, and a box surrounded by four panels. The top cover, box body, and bottom plate are provided with a film layer, and the inside of the joint between two adjacent panels A support column is provided, the lower end of the support column is fixedly connected to the bottom plate, the outer side of the support column is fixedly connected to the junction of two adjacent panels, and the upper end of the support column is in contact with the upper cover surface;

The film layer is a PVC film layer;

The support column is made of corrugated cardboard. the

The utility model adopts a layer of PVC film on the upper cover, the box body and the bottom plate, and the PVC film layer has waterproof ability, so that the cardboard will not get wet under the protection of the PVC film layer when it encounters a humid environment. . At the same time, the PVC film layer can be recycled and reused as a material, thus saving the cost of the manufacturer. The utility model uses corrugated cardboard as a support column, which enhances the pressure resistance of the packaging carton and avoids damage caused by heavy objects. Hazard to the contents of the box. the

The beneficial effects of the utility model are: adopting the technical solution provided by the utility model, the cardboard used for packaging has the ability of waterproofing, and at the same time, the strength of the cardboard is also improved due to the addition of the PVC film layer and the corrugated board support column, and the material can be recycled and reused , environmental protection, reduced production costs. the
