Corrugated board and flat layer of corrugated cardboard

摘要

The invention relates to constructive implementation of paper or paperboard laminate, which is used, inter alia, in the production of packages. The technical result of the claimed solution is simultaneously wet strength imparting hydrophobic properties and corrugated paperboard and cardboard and paper layers used for the production of corrugated cardboard, which will increase the resistance to water. Also, the technical result is to ensure the recycling of used packaging equipment without contaminating elements, resulting in reduced time and labor for processing. The claimed technical result is achieved through the use of corrugated cardboard (corrugated board), consisting of flat and corrugated sheets, at least one of the sheets which is pasted and / or impregnated in the mass of wet strength resin and a hydrophobic adhesive, wherein as the wet strength resins are used poliamidaminepihlorgidrinovye resin or formaldehyde resins, as well as the hydrophobic adhesive used alkenilketena dimers or alkyl, alkyl- or alkenylsuccinic anhydrides, rosin, starch, maleic anhydride, acrylic islotu, acrylamide. The technical result is achieved by using design corrugated sheet comprised of at least two layers, at least one of the layers which is pasted and / or impregnated in the mass of wet strength resin and a hydrophobic adhesive, wherein as the wet strength resins are used poliamidaminepihlorgidrinovye resins or formaldehyde resins, as well as the hydrophobic adhesive used alkenilketena dimers or alkyl, alkyl- or alkenylsuccinic anhydrides, rosin, starch, maleic anhydride, acrylic acid, acre Lamido.
