Embodiment Construction

[0016] The present invention will be further illustrated below in conjunction with specific examples, which are implemented on the premise of the technical solutions of the present invention. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention.

[0017] like Figure 1-3 As shown, a honeycomb paperboard for packaging includes a honeycomb column layer 1, and the cross-sectional shape of the honeycomb column layer is a regular hexagon or a rhombus.

[0018] The honeycomb column layer is provided with a face paper layer 2 up and down, and the face paper layer 2 is selected from corrugated cardboard, kraft cardboard, yellow cardboard, white cardboard or impregnated liner cardboard commonly used in the market.

[0019] A sandwich layer 3 is arranged between the honeycomb column layer 1 and the panel layer 2; the longitudinal section of the sandwich layer 3 is triangular (such as figure 1 s...

Abstract

The invention discloses a honeycomb cardboard for packaging. The honeycomb cardboard for packaging comprises a honeycomb column layer, wherein surface paper layers are arranged on the upper side and the lower side of the honeycomb column layer; sandwich layers are arranged between the honeycomb column layer and the surface paper layers; the longitudinal sections of the sandwich layers are triangular, trapezoidal or wavy; air passages are formed in the honeycomb column layer and the sandwich layers; closed structures are formed between the sandwich layers and the surface paper layers; a moisture absorbent is arranged inside the closed structures. The invention provides the honeycomb cardboard which is simple in structure, can guarantee air discharge of a honeycomb core without drilling holes in the honeycomb core during production, is waterproof and moisture-proof and has improved puncture resistance.

Description

technical field [0001] The invention belongs to the technical field of packaging paper products, in particular to a honeycomb paperboard for packaging. Background technique [0002] Honeycomb cardboard is a packaging paper product that connects countless hollow three-dimensional hexagonal components by gluing method into a whole, with strong bearing capacity, good compressive performance, can bear large plane pressure, good buffer performance, honeycomb core The greater the thickness, the greater the absorption of impact energy and the better the cushioning effect. Honeycomb cardboard is bonded by honeycomb core and corrugated cardboard and then dried and shaped. Because the honeycomb core is a sealed space structure, the gas in the honeycomb core cannot be discharged during drying, which is easy to cause blistering and unevenness on the corrugated cardboard. Traditional The method is to punch holes on the honeycomb core to realize air circulation and ensure the processing ...
