Description

Technical Field

[0001] The utility model relates to the technical field of packaging materials, and more specifically, to an environmentally friendly moisture-proof composite packaging material. Background Art

[0002] Among all kinds of packaging for industrial products, corrugated boxes have become the mainstream in the packaging industry. They are lightweight, foldable, low-cost, environmentally friendly, easy to change in specifications, can be printed with high quality, and can be used as a renewable resource after recycling. Therefore, their scope of use is becoming wider and wider. The commonly used corrugated cardboard on the market is a multi-layer adhesive body, which is composed of at least a layer of corrugated core paper interlayer and a layer of cardboard.

[0003] Patent publication number CN210851619U discloses an environmentally friendly moisture-proof composite packaging material comprising a waterproof outer layer, an inner support layer, and a reinforced inner layer. The inner support layer comprises a first baffle, a first support plate layer, a second baffle, a second support plate layer, a third baffle, and a rubber interlayer. A moisture-proof inner layer is disposed between the waterproof outer layer and the first baffle. The first baffle, first support plate layer, second baffle, second support plate layer, and third baffle are arranged in order from the outside in. This utility model ensures the waterproof and moisture-proof properties of the composite packaging material, while also being able to absorb significant impact loads and exhibit excellent tear resistance. This effectively enhances the composite packaging material's thermal insulation properties, protecting items contained within corrugated cardboard packaging boxes from the effects of high temperatures.

[0004] However, in actual use, the waterproof outer layer of this structure does not have an anti-ultraviolet function, so it is easy to age when used outdoors, reducing its durability. In addition, the flame retardant layer does not have a static dissipation function, so when static electricity accumulates, the flame retardant layer is prone to failure, resulting in the risk of causing a fire. Therefore, an environmentally friendly moisture-proof composite packaging material is proposed. Utility Model Content
