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. -
What Happens to Cellulosic Fibers During Papermaking and Recycling? a Review
PEER-REVIEWED REVIEW ARTICLE ncsu.edu/bioresources WHAT HAPPENS TO CELLULOSIC FIBERS DURING PAPERMAKING AND RECYCLING? A REVIEW Martin A. Hubbe,* Richard A. Venditti, and Orlando J. Rojas Both reversible and irreversible changes take place as cellulosic fibers are manufactured into paper products one or more times. This review considers both physical and chemical changes. It is proposed that by understanding these changes one can make better use of cellulosic fibers at various stages of their life cycles, achieving a broad range of paper performance characteristics. Some of the changes that occur as a result of recycling are inherent to the fibers themselves. Other changes may result from the presence of various contaminants associated with the fibers as a result of manufacturing processes and uses. The former category includes an expected loss of swelling ability and decreased wet-flexibility, especially after kraft fibers are dried. The latter category includes effects of inks, de-inking agents, stickies, and additives used during previous cycles of papermaking. Keywords: Paper recycling, Drying, Deinking, Hornification, Inter-fiber bonding, Refining, Fines, Fiber length, Conformability Contact information: Department of Forest Biomaterials Science and Engineering, Box 8005, North Carolina State University, Raleigh, NC 27695-8005, USA; *Corresponding author: [email protected] INTRODUCTION Cellulosic fibers can change significantly when formed into a wet web of paper and subsequently subjected to such processes as pressing, drying, printing, storage, repulping, and deinking. Some of the changes can be subtle. Often it is possible to substitute recovered fibers in place of virgin fibers used for the production of paper or paperboard. On the other hand, characteristic differences between recycled fibers and virgin fibers (fresh from pulping wood, not recycled) can be expected; many of these can be attributed to drying. -

OIsson Packaging of products for storage and shipment has a history which extends back 5000 years to stone cosmetic kits of MeSOpotamia. Over the years since that time, various package forms have become dominant methods for the shipment of goods. Some, such as leather bags, kegs, barrels, and wooden boxes have nearly completely disappeared from use. Packages serve several functions in the distribution of goods to the market place. Packages protect the product and protect the environ- ment, make goods convenient to handle, store, ship, and use, and moti- vate the customer to buy the product and use it correctly. Shipping packages accomplish these functions within a distribution system which extends from the product-producing center, through the distribution channel, to the point where the consumer uses the product and disposes of the package. -
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. -
The Renaissance Spreads Outside of Italy
5/9/2019 Big Idea The Renaissance Spreads Outside of Italy Essential Question How did the Renaissance spread to the rest of Europe? 1 5/9/2019 Words To Know Renaissance - “rebirth” in French, the Renaissance was a cultural movement in the 14th-17th centuries during which European artists, scientists, and scholars, were inspired by the achievements of the Greeks and Romans. Let’s Set The Stage… As the Renaissance began to grow in Italy, northern Europe was still recovering from the ravages of the Black Death. But by the 1400s, the cities of the north began to enjoy the economic growth—and the wealth—needed to develop their own Renaissance. 2 5/9/2019 The Spread of Wealth Through Trade Trade routes that existed since the Roman Empire were infused by new wealth and products when trade between the Italian city-states and the Ottoman Empire increased. The Spread of Wealth Through Trade As a result, cities like Cologne, Bruges, Paris, London, and Lisbon became centers of trade and banking. Like in Italian cities, trade led to the establishment of a wealthy class of traders and bankers who supported architects and paid for work from artists. 3 5/9/2019 Papermaking By 1300, papermaking and printing technology reached Europe from China and the Middle East. Papermaking Paper making had contributed to golden ages in China and the Middle East, and to the preservation (saving) of Greek and Roman learning that had been “lost” in Europe and preserved (saved) by scholars (students) in the Ottoman Empire. 4 5/9/2019 The Earliest Books The earliest books were written on scrolls. -

NHBB Nationals Bee 2018-2019 Bee Round 1 Bee Round 1 Regulation Questions (1) This man, as Public Safety Director of Cleveland, controversially ordered the burning of its shanty towns in response to the Cleveland Torso Murderer. This man co-wrote a memoir with Oscar Farley which was named for a term coined by Charles Schwarz. George Johnson appointed this man to head a group dedicated to prosecuting criminals under the Volstead Act. This man's inability to be bribed by the Chicago Outfit led him and his men to be labeled the \Untouchables." For the point, name this Prohibition-era crime fighter who helped bring down Al Capone. ANSWER: Eliot Ness (2) One woman during this period was strangled after her infant son, nicknamed “offspring of the thief," was hanged. Jacob De La Gardie helped defeat the Rebel of Tushino during this period, but defected when Dmitri Shuisky failed to lift the Siege of Smolensk after being defeated by winged hussars at the Battle of Klushino. This period began after Feodor the Bellringer was briefly succeeded by Boris Gudonov. At least four pretenders to the throne named False Dmitris appeared during, for the point, what tumultuous era which ended with the accession of Michael Romanov? ANSWER: Time of Troubles (3) During this conflict, Wilhelm II requested Abdul Hamid II to stop Muslim troops from fighting. Those forces murdered Sugiyama Akira during this conflict and repelled the Seymour expedition. The Militia United in Righteousness fought alongside those forces, the Gansu Braves, in this conflict, where their siege of the Legation Quarter was lifted by the Eight-Nation Army. -
Born As Twins - Papermaking and Recycling
1 Born as twins - papermaking and recycling Boris Fuchs, Frankenthal, Germany Abstract: It will be shown that in the year 105 AD., when the purchasing administrator at the Chinese Emperor’s Court, G-ii Ltm, invented, or better said, recorded the papermaking process, it was common practice to recycle used textile clothes, fishing nets and the hemp material of ropes to get a better and cheaper (less labour intensive) raw material for papermaking than the bark of mulberry trees, bamboo and china grass. When the art of papemaking, on its long march through the Arabian World, came to Europe, used textile rags were the only raw material, thus recycling was again closely related to papermaking, and to secure the paper-maker’s business base, it was strictly forbidden to export textile rags to other countries. Despite heavy punishments, smuggling flourished at that time. The &inking process was invented in 1774 by Julius Claproth and bleaching by Claude Louis Berthollet in 1785, but with the introduction of ground wood in 1845 by Friedrich Keller, recycling lost its preferential status in the paper manufacmring industry by the second half of the 20ti century, when economic considerations, especially in Central Europe, caused its comeback, long before ecological demands forced its reintroduction and environmental legislation was set in place. Thus recycling with papermaking is not an invention of the present time, but a twin arrangement right from the beginning. For the future, a certain balance between primary and secondary fibre input should be kept to avoid any collapse in the paper strength by too often repeated recycling., also to assist the forest industry in keeping our forests clean and healthy. -
