The Influence of the Packing Material Type on the Adhesive Joints Strength of the Paperboard Packages

Abstract

This article presents selected issues related to the impact of the material factors on the adhesive joints’ strength of the paperboard packages and strength of various types of the packaging materials: Alaska Plus GC2 (grammage 235 g and 280 g) and Crescendo C1S (grammage 300 g). The bonded material consisted of different types of paperboard used in production of packages, which were subject to the surface modification process by applying a varnish coat and, in case of one material, to the lamination process. The adhesive joints were made with use of a cold adhesive produced by SALTADIS (identification number: SI 5240). It is water-soluble and may be used for a variety of industrial applications. The adhesive joints were made with use of different packaging materials and different technological modifications of these materials’ surface on an automated production line. It was in order to determine which material and which surface modification method has an impact on both the strength of the adhesive joints and the packaging material itself. Based on the packaging materials’ properties, it was observed that together with the increase of the basis weight, the material’s strength also increases. In addition, the lamination process increases the material’s strength as well.
