Publication number: 20190176430Abstract: A blank has an upper surface and a reverse surface. The upper surface is printed in a conventional manner and includes outer side panels and inner side panels. Attachment regions are provided on the inner side panels of the outer surface, and corresponding attachment regions are provided on the outer side panels of the reverse surface. During assembly the respective attachment regions are arranged to face one another and an adhesive is provided therebetween. In the present method, the attachment regions of the upper surface initially have a surface tension in the range from around 34 dynes/cm to 60 dynes/cm before the upper surface is printed. The attachment regions are treated in order to maintain a surface tension in the desired range of 34 dynes/cm to 60 dynes/cm, following printing and before any adhesive is applied. This is achieved by applying an auxiliary printing medium to the attachment regions.Type: ApplicationFiled: September 26, 2017Publication date: June 13, 2019Applicant: JT International S.A.Inventors: Kenta Tanaka, Dominic Lukasz Latuszek, Mike Clausen
