Water-soaked corrugated cardboard can easily collapse with irreversible shape . Corrugated fiberboard is a paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards. Recycling itself is a pro-ecological and absolutely necessary process, but the mechanical properties of materials that are processed many times deteriorate with the number of cycles. This squishy wood pulp is rolled out into thin sheets in paper mill factories to form the papers and boards that we use. To use corrugated cardboard and design packaging from this material it is very important to know its mechanical properties.

The orientation of the fibers, shown in Figure 2, makes the corrugated board stronger along the direction of the wave. Physical and mechanical properties of cardboard panels made from used beverage carton with veneer overlay were examined by Ayrilmis et al. zThe physical properties of paper are based on the structure of the cellulose molecule, the type of fiber, and how that fiber was separated from the other components of the wood. [9,10] Corrugations and other spatial organization of mate-rials can also be used to make otherwise rigid materials pliant Adv. Corrugated Box Layers. • Chemical factors: The degree of delignification, the degree of polymerisation of cellulose DP, the content first idea of a fluted paper!1874 Oliver Long suggested the creation of the single face board!Late 1870, Machinerywas developed to make corrugated board!1890 Another liner was added which resulted the first single wall corrugated board . On the other hand, the width of corrugated cardboard and peak load are two important parameters for the application of it for the vibration isolation. Without corrugated cardboard, the world of packaging would find it difficult to distribute, store and protect the product until it reaches the functionality for which it was designed. These packages have limited life span and, after use, contribute for increasing the waste stream on the planet. The humble cardboard box is the unsung hero of countless deliveries every day. Common paper, card and boards for commercial and everyday use have a range of advantages and disadvantages. The corrugated medium and linerboard are made of containerboard, a paper-like material usually over 0.01 inches (0.25 mm) thick. Mechanical and building physical properties are obtained for different kinds of corrugated cardboard as well as for different orientations. while he was listening to a presentation on the mechanical properties of the . Corrugated cardboard packs and protects more than 34% of European goods, but if cardboard is wet, the box collapses and the content loses its value. Corrugated boards can be made more weather proof through wet-strength, water resistance treatment and adhesives such as corrugated and solid fiberboard sheet stock and fabrication of fiberboard shipping containers. As a component of corrugated cardboard is paper, it is also able to be considered as an orthotropic material. It allows the packaging to be stiffer while using less fiber. A number of typical tests have been developed to standardize the process of the characteri‐ zation of corrugated cardboard mechanical properties. Paperboards and corrugated cardboard are some of the most used products in packaging today. However, exposure to water or humidity is highly destructive toward cardboard mechanical properties. . By using simple test methods such as the Edge Crush Test (ECT), companies benefit from understanding the maximum weight a box can withstand and the overall stacking strength. Therefore, the corrugated cardboard can be observed both from technological and environmental aspects.Five layered corrugated cardboard of different types of flute profile was used for this research. Corrugated cardboard has insulating properties due to the fluting design of its interior. : 901-419-4848 Emergency Telephone Number Emergency Number : 1-800-424-9300 (North America)/ 1-703-527-3887 (International) ISRN Mechanical Engineering 3 Fully modeled corrugated sheet (3D) y x Ly Lx Analytical expressions Orthotropic model (2D) Ly Lx Figure 2: Models used in modal analysis and extensional test. This idea arises from the fact that the collapse of the box is given by the local bucking of the corrugated cardboard panels, due to the slenderness itself, and the properties in the compression direction are predominant. Water-soaked corrugated cardboard can easily collapse with irreversible shape . Apart from the above‐mentioned , and .mm. Thus . Published 2006. For that, corrugated cardboard sheets are glued to build billets for testing, and an equivalent elastic modulus is obtained. By using simple test methods such as the Edge Crush Test (ECT), companies benefit from understanding the maximum weight a box can withstand and the overall stacking strength. ling the cost of corrugated cardboard production, mechanical properties depend directly on flute profile. used to unitize products into packages of size and shape suitable for manual or mechanical handling and to protect the contents against environmental, handling, shipping, and storage conditions. The aims of the thesis were to study how washboarding (the undulations present on the surface of corrugated cardboard used to manufacture boxes) relates to the mechanical properties of paper and the board manufacturing conditions and to examine the impact.

This design provides the optimum combination of low weight and high stiffness. Therefore, the arched flutes allow the cardboard to tolerate more external force. The simultaneous heat and mass transport in paper . The model of corrugated board with three or more flutes is reliable for stress and . Its most important feature is that it is inexpensive, easy to be printed and to recycle. The material was originally invented in England as a liner for tall hats but the design was patented as a shipping material in 1871. The experimental cardboards from recycled food and beverage carton containers having approximately 75% paperboard, 20% low density polyethylene (LDPE), and 5% aluminum foil were overlaid using four types of adhesives; polyurethane, phenol-formaldehyde, urea-formaldehyde, and . Mechanical Hi, I am working on a university project where I am essentially design a fancy box made out of 2 ply corrugated board and cardboard. Properties of Corrugated Cardboard by Roger Smith / in Money Corrugated cardboard is a lightweight, low cost and potentially eco-friendly storage and packaging material. The orientation of the fibers, shown in Figure 2, makes the corrugated board stronger along the direction of the wave. Symmetry directions are defined according to the notation adopted for the paper: the machine direction (MD) corresponds to the winding direction The corrugated cardboard is an orthotropic sandwich with the surface plies (facing) providing bending stiffness, separated by a lightweight corrugated core (fluting) that provides shear stiffness. in the paper industry for the estimation of the corrugated board load‐bearing capacity. For corrugated paperboard, the compressive strength, crush strength, bending defection and flexural stiffness, creep property and recoverability, and the mechanical behaviors such as buckling, transverse shear, elasticity, stability, collapse and ultimate failure were investigated by Hahn, Lee, Urbanik, Guo, Nordstrand, Aboura, Talbi et al. table 1 properties of adhesives used for panels manufacture adhesive type between cardboard and veneer sheet solids content specific gravity ph gel time viscosity (%) (g/cm3) (at 20 °c) (at 100 °c) (s) (at 20 °c) (cps) polyurethane (pu) (diphenylmethane- component a (macroplast 100 1.400 - - 37,000 4,40 -di-isocyanate) uk 8103) component b … Some of these include: Moisture content rnges from 6.5-9.5%. The Kaplan formula calculates the compressive strength of the carton according to the physical properties of the base paper to see whether it can meet the requirements; or according to the predetermined compressive strength requirements of the corrugated box, the mechanical corrugated board base paper can be selected. On the one hand, a mathematical model of strength and deformation of boxes with different geometry is obtained . School of Mechanical and Power Engineering, East China University of Science and Technology, Shanghai 200237, China Email: y30160358@mail.ecust.edu.cn, clliu@ecust.edu.cn TEL: 18221957873 Abstract: This paper studies the application of corrugated cardboard in vibration isolators. According to Teachers Domain, when force is applied to an arch, it transfers along the curve of the arch to the base. Corrugated cardboard has very good mechanical properties, which means that it is lightweight, strong, and resistant to moisture [Henlon 1998]. . The humble cardboard box is the unsung hero of countless deliveries every day. Designing corrugated board packaging is a real challenge, especially when the packaging material comes from multiple recycling. As a component of corrugated cardboard is paper, it is also able to be considered as an orthotropic material. This design provides the optimum combination of low weight and high stiffness. To reduce computational effort of finite element (FE) calculations a corrugated sheet is replaced with an orthotropic plate. Corrugated board, as a fibrous material, is characterized by strong orthotropy. 1, a sketch of an actual region of corrugated board is represented. Several properties and characteristics can be measured for corrugated board. It is assumed that the characteristic shape of the wave has a positive effect on its mechanical properties. Paper and paperboard are more than twice as stiff in the machine direction (MD) than in the cross direction (CD). [4-10].
