Packaging special paperboard with waterproof function

Abstract

The invention discloses a packaging special paperboard with a waterproof function. The paperboard includes a first paperboard body and a second paperboard body, a netted metal layer, a waterproof layer and a high-density paper fiber layer are sequentially arranged between the upper surface of the first paperboard body and the lower surface of the second paperboard body, the upper surface of the second first paperboard body is coated with a first flame-retardant layer and a third paperboard body arranged on the first flame-retardant layer, the third paperboard body is divided into bottom layerpaper and surface layer paper, color fibers are dispersed in the surface layer paper at random, and plastic wires with aluminum-plated layers or aluminum-plated plastic wires with hologram images areembedded into an interface of the bottom layer paper and the surface layer paper. The special paperboard has the advantages of visual and easy anti-fake identification property and distinctive anti-fake characteristics, is high in strength and not easy to burn or damage and solves the problems urgently needed to be solved in the field of special paperboards.

Description

technical field [0001] The invention belongs to the technical field of cardboard, and in particular relates to a special cardboard for packaging with waterproof function. Background technique [0002] Good packaging of goods has been a difficult problem that has plagued producers and operators for a long time. For example, good packaging involves: the hardness of the paper used to package goods, whether it has anti-counterfeiting marks, whether it is flame retardant, etc. The most common anti-counterfeiting mark is to stick an anti-counterfeiting laser label on the packaging paper, but because the production cost of the laser label is low and it is easy to counterfeit, its anti-counterfeiting effect is not very ideal. In recent years, more anti-counterfeiting products have been developed, such as holographic anti-counterfeiting labels, telephone anti-counterfeiting labels, code anti-counterfeiting labels, watermark anti-counterfeiting labels, etc., made by various applicati...

AI Technical Summary

Problems solved by technology

But these anti-counterfeiting marks also have their own defects. For example, the watermark anti-counterfeiting marks are easy to be counterfeited, the code anti-counterfeiting marks can only be verified online after buying the goods, and the telephone anti-counterfeiting marks can only be used for those who are familiar with the anti-counterfeiting inquiry phone. Because the anti-counterfeiting inquiry phone can also be counterfeited

Conventional packaging paper is easy to be damaged when subjected to external shocks under the condition of poor loading and unloading conditions and storage and transportation environment, which affects sales

At the same time, when it is in a dry or flammable place, because conventional paper does not have flame retardancy, it is easy to burn quickly and damage the product
