Description

Technical Field

[0001] The utility model relates to the technical field of packaging materials, in particular to a packaging material plate with good moisture resistance. Background Art

[0002] Packaging materials refer to materials used to manufacture packaging containers, packaging decoration, packaging printing, packaging transportation, etc. to meet product packaging requirements. They include metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, composite materials and other main packaging materials, as well as strapping, decoration, printing materials and other auxiliary materials. Paperboard is one of them, but paperboard is not resistant to moisture. During long-term storage, it is easy to crack, affecting its use. To address this problem, existing packaging material paperboards ensure the dryness of the paperboard layer structure by adding desiccant and edge banding strips to the paperboard layer. However, in fact, the reason why paperboards are damp is mostly because water molecules in the air contact the paperboard layer, causing it to become soft and cracked.

[0003] On the one hand, the existing packaging material paperboard lacks support and stability between the layer structures, and on the other hand, adding desiccant between the layer structures is not conducive to ensuring the adhesion between the layer structures and the daily use of the paperboard.

[0004] Therefore, the utility model provides a packaging material plate with good moisture resistance. Utility Model Content

[0005] In view of the defects in the prior art, the utility model provides a packaging material board with good moisture resistance, which can solve the following problems: the existing packaging material paperboard has a lack of support and stability between the layer structures; the addition of desiccant between the layer structures is not conducive to ensuring the adhesion between the layer structures and the daily use of the paperboard.

[0006] In order to solve the above technical problems, the utility model proposes the following technical solutions:

[0007] A packaging material plate with good moisture resistance comprises an inner base layer and an outer base layer which are stacked together, a release protective film being fixedly connected to the surface of the outer base layer, an anti-cracking layer and a moisture-proof layer being fixedly connected to the interior and the outer surface of the inner base layer respectively, a supporting structure being fixedly arranged between the inner base layer and the outer base layer, supporting structures being arranged at upper and lower positions between the inner base layer and the outer base layer, a plurality of supporting structures being arranged in a transverse arrangement along the inner surface of the outer base layer, and an inner end of the supporting structure being fixedly connected to the moisture-proof layer.

[0008] Furthermore, the support structure includes a support base layer arranged in a trapezoidal shape and an inner support tube arranged in a cylindrical shape inside the support base layer, and an arc-shaped support side edge is fixedly connected to the outer side of the inner support tube.

[0009] Furthermore, the top ends of the supporting base and the supporting side edges are fixedly connected to the inner surface of the outer base, the supporting side edges are arc-shaped and concavely extended outward, and the top of the inner supporting tube is simultaneously arranged to fit the bottom surface of the outer base.

[0010] Furthermore, the supporting base and the supporting sides are configured as corrugated paper tubes.

[0011] Furthermore, the anti-cracking layer is configured as a woven wire layer, which is located at the upper and lower positions inside the inner base layer and is bonded to the inner base layer by sticky glue. The moisture-proof layer is configured as a plastic film moisture-proof layer and is bonded to the outer surface of the inner base layer by sticky glue.

[0012] Furthermore, the release protective film and the outer base layer are arranged to be peelable and adhered to each other.

[0013] It can be seen from the above technical solution that the beneficial effects of the utility model are:

[0014] 1. The supporting base and supporting side edges provide a hard support effect between the outer base and the inner base, and the inner supporting tube provides a soft buffer effect between the outer base and the supporting base.

[0015] 2. The integrity of the inner base layer is ensured by the anti-cracking layer, which can effectively prevent the inner base layer from separating after being damp. The moisture-proof layer can further improve the moisture-proof effect from the inside of the entire material cardboard. BRIEF DESCRIPTION OF THE DRAWINGS

When using the device, when it is necessary to paste or assemble the surface of the entire material cardboard, the release protective film 9 can be removed. During the use of the entire material cardboard, the supporting structure 5 can effectively provide it with stable support, and the anti-cracking layer 3 and the moisture-proof layer 4 inside and on the surface of the inner base layer 1 can effectively prevent the entire material cardboard from becoming soft and cracked due to moisture.

[0025] In the embodiment of the utility model, the support structure 5 includes a supporting base layer 6 arranged in a trapezoidal shape and an inner supporting tube 7 arranged in a cylindrical shape on the inner side thereof.
