Publication number: 20180207895Abstract: Cardboard with edges sealed by a mixture of hot-melt adhesive and wax includes two surface sheets and an intermediate core material. The surface sheets have a pair of corresponding edges that form an edge opening therebetween communicating with the interstitial spaces in the cardboard and sealed by an edge-sealing structure in the interstitial spaces. The edge-sealing structure includes a primer layer formed by an adhesive mixture and a sealing layer formed by a sealing mixture. The adhesive mixture is made by mixing the hot-melt adhesive with the wax, adhesively bonds the surface sheets and the intermediate core material together, and forms the primer layer with voids and providing a porous supporting surface to be coated with the sealing mixture. The sealing mixture is less adhesive than the adhesive mixture and fills up the voids in the primer layer. Thus, the cardboard achieves waterproofness and thermal and acoustic insulation at low cost.Type: ApplicationFiled: May 9, 2017Publication date: July 26, 2018Inventor: Chi-Wah LAU
