ABSTRACT This paper shows the technological development for manufacturing corner angle sections or cardboard. Its manufacture involves splicing sheets (liners) of different weight Kraft papers joined with white glue. The thickness and strength of each profile is determined by the amount of spliced leaves and paperweight. There are two types of finishing in the profile, which are: natural finish Kraft wrapping paper and the white paper envelope. The second one is used to print images or logos on the exterior face for advertising purposes. They can withstand bending stresses for supporting buckling in horizontal and vertical position. These profiles are mainly used for packaging, protect corners, transportation and storage. A machine for manufacturing specialized linear process to obtain the required thickness is used. In this article, the basic load of an angular profile is analyzed by the finite element method using ANSYS 14 ®. Mechanical design considerations based on the mechanics of composite materials and the theory of laminated beams are considered. With the results of this analysis, load capacities like bending, buckling and deformation profiles are obtained. Furthermore, a comparison of three thicknesses of angular profiles supporting the mentioned loads is also presented.
INTRODUCTION In recent decades, packaging systems evolved due to the high demand for products that companies require. A transport package is required to be strong and lightweight in order to be cost effective. Furthermore, it should be recycled because the environmental and economic concerns [1]. Despite of the undeniable appeal and importance of packaging, transportation and protection of products, there are very little scientific research works about the mechanical behavior of a paper board profile, its use in an optimum manner requires the knowledge of its mechanical behavior: elastic, inelastic, failure, etc., [2]. Due to the conditions of use required, in this paper, two important behaviors are analyzed, bending and buckling. Finite element simulation revealed that the profile has the ability to support the required loads. So, these data can be used as a tool to ensure the customer that the product will arrive in a better condition to the point of sale.

Paper board profile The paperboard profile is a set of liners of Kraft paper or white paper of different weights joined with adhesive and forming an angle of 90°. Figure 1 shows the shape of the profile. The function is determined by its angular shape and the length of both sides can have diffe
