Corrugated Board Structure: a Review M.C
ISSN: 2395-3594 IJAET International Journal of Application of Engineering and Technology Vol-2 No.-3 Corrugated Board Structure: A Review M.C. Kaushal1, V.K.Sirohiya2 and R.K.Rathore3 1 2 Assistant Prof. Mechanical Engineering Department, Gwalior Institute of Information Technology,Gwalior, Assistant Prof. Mechanical Engineering 3 Departments, Gwalior Engineering College, Gwalior, M. Tech students Maharanapratap College of Technology, Gwalior, [email protected] [email protected] [email protected] ABSTRACT Corrugated board is widely used in the packing industry. The main advantages are lightness, recyclability and low cost. This makes the material the best choice to produce containers devoted to the shipping of goods. Furthermore examples of structure design based on corrugated boards can be found in different fields. Structural analysis of paperboard components is a crucial topic in the design of containers. It is required to investigate their strength properties because they have to protect the goods contained from lateral crushing and compression loads due to stacking. However in this paper complete and detailed information are presented. Keywords: - corrugated boards, recyclability, compression loads. Smaller flutes offer printability advantages as well as I. INTRODUCTION structural advantages for retail packaging. Corrugated board is essentially a paper sandwich consisting of corrugated medium layered between inside II. HISTORY and outside linerboard. On the production side, corrugated In 1856 the first known corrugated material was patented is a sub-category of the paperboard industry, which is a for sweatband lining in top hats. During the following four sub-category of the paper industry, which is a sub-category decades other forms of corrugated material were used as of the forest products industry. -

Making Paper from Trees
Making Paper from Trees Forest Service U.S. Department of Agriculture FS-2 MAKING PAPER FROM TREES Paper has been a key factor in the progress of civilization, especially during the past 100 years. Paper is indispensable in our daily life for many purposes. It conveys a fantastic variety and volume of messages and information of all kinds via its use in printing and writing-personal and business letters, newspapers, pamphlets, posters, magazines, mail order catalogs, telephone directories, comic books, school books, novels, etc. It is difficult to imagine the modern world without paper. Paper is used to wrap packages. It is also used to make containers for shipping goods ranging from food and drugs to clothing and machinery. We use it as wrappers or containers for milk, ice cream, bread, butter, meat, fruits, cereals, vegetables, potato chips, and candy; to carry our food and department store purchases home in; for paper towels, cellophane, paper handkerchiefs and sanitary tissues; for our notebooks, coloring books, blotting paper, memo pads, holiday greeting and other “special occasion’’ cards, playing cards, library index cards; for the toy hats, crepe paper decorations, paper napkins, paper cups, plates, spoons, and forks for our parties. Paper is used in building our homes and schools-in the form of roofing paper, and as paperboard- heavy, compressed product made from wood pulp-which is used for walls and partitions, and in such products as furniture. Paper is also used in linerboard, “cardboard,” and similar containers. Wood pulp is the principal fibrous raw material from which paper is made, and over half of the wood cut in this country winds up in some form of paper products. -

CHANGES IN PRINT PAPER DURING THE 19TH CENTURY AJ Valente, ([email protected]), President, Paper Antiquities When the first paper mill in America, the Rittenhouse Mill, was built, Western European nations and city-states had been making paper from linen rags for nearly five hundred years. In a poem written about the Rittenhouse Mill in 1696 by John Holme it is said, “Kind friend, when they old shift is rent, Let it to the paper mill be sent.” Today we look back and can’t remember a time when paper wasn’t made from wood-pulp. Seems that somewhere along the way everything changed, and in that respect the 19th Century holds a unique place in history. The basic kinds of paper made during the 1800s were rag, straw, manila, and wood pulp. -
