Zinc and Cadmium in Paper (Reaffirmation of T 438 Cm-96)
WI 050114.01 T 438 DRAFT NO. 5 DATE July 27, 2006 TAPPI WORKING GROUP CHAIRMAN J Ishley SUBJECT CATEGORY Fillers & Pigments Testing RELATED METHODS See “Additional Information” CAUTION: This Test Method may include safety precautions which are believed to be appropriate at the time of publication of the method. The intent of these is to alert the user of the method to safety issues related to such use. The user is responsible for determining that the safety precautions are complete and are appropriate to their use of the method, and for ensuring that suitable safety practices have not changed since publication of the method. This method may require the use, disposal, or both, of chemicals which may present serious health hazards to humans. Procedures for the handling of such substances are set forth on Material Safety Data Sheets which must be developed by all manufacturers and importers of potentially hazardous chemicals and maintained by all distributors of potentially hazardous chemicals. Prior to the use of this method, the user must determine whether any of the chemicals to be used or disposed of are potentially hazardous and, if so, must follow strictly the procedures specified by both the manufacturer, as well as local, state, and federal authorities for safe use and disposal of these chemicals. Zinc and cadmium in paper (Reaffirmation of T 438 cm-96) (no changes were made since last draft) 1. Scope and significance 1.1 This method maybe used for the determination of cadmium and zinc either in paper or in highly opaque pigments. Zinc is usually present in zinc oxide, zinc sulfide, or as lithopone (a combination of zinc sulfide and barium sulfate), which is occasionally used in filled paper, in paper coatings and in high-pressure laminates and wallpaper. -

Department of Chemical and Biological Engineering Göteborg, Sweden 2012 Decreased wet strength in retorted liquid packaging board Maria Gunnarsson Department of Chemical and Biological Engineering Division of Organic Chemistry CHALMERS UNIVERSITY OF TECHNOLOGY ABSTRACT The Tetra Recart is a retortable food packaging, suitable for high viscous products, making it able to replace most food cans used for storage of food today. The packaging is built up by a paperboard, consisting of an unbleached bottom layer and a bleached top layer. Polymers and aluminium further cover the paperboard in order to protect the food against moisture and light, causing degradation. During the retorting process, the packaging develops a certain wet strength making it hard to disintegrate the pulp fibres in the board. The phenomenon of the developed wet strength is of high interest when inventing and developing new packaging materials. To investigate why and how the phenomenon occurs, a series of trials were made through production of laboratory sheets with subsequent disintegration. -

ITP Forest Products: Development of Screenable Pressure Sensitive Adhesives
Development of Screenable Pressure Sensitive Adhesives Final Report for Project DE-FC07-00ID13881 By Steven J. Severtson (Principal Investigator) XinPing Wang, Michael J.

Fuller Company, 1200 Willow Lake Boulevard, St. Paul, MN 55110 Jennifer A. Lien Boise Paper Solutions, 400 Second Street, International Falls, MN 56649 Carl J. Houtman and Karen L. Scallon USDA Forest Service, Forest Products Laboratory, One Gifford Pinchot Drive Madison, WI 53705 November 28, 2003 Executive Summary Several approaches were examined for meeting the project objective of developing pressure sensitive adhesive (PSA) products that are engineered for enhanced removal during the processing of recycled fiber, also known as environmentally benign PSAs. These included the 1.) design of environmentally benign PSA films, 2.) development of paper face stock with high screening removal efficiencies that retain attached PSA films and 3.) modification of face stock surface properties to enhance the removal of PSA films. All three approaches yielded promising laboratory results that were confirmed at the pilot scale and appear to be commercially viable. Most of this study focused on hot-melt formulations, which compose a smaller portion of the PSA label market than water-based formulations. However, hot-melt formulations are considerably less complex and allow great flexibility for property modifications. The results of this research -

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 Method of Making Models from Sheets of Blotting Paper
THE METHOD OF MAKING MODELS FROM SI-IEETS OF BLOTTING PAPER. BY SUSANNA PHELPS GAGE. Ithaca, New York. The Born Method of reconstructing models from wax plates is in use in all the larger laboratories of Anatomy and Embryology. Various modifications of that method have been introduced, notably at Johns IIopkins University. For smaller laboratories and isolated investigators the wax plates are difficult to prepare or to obtain already made. More- over, in the larger laboratories ihe preparation of the plates is a much dreaded piece of drudgery to be done in the basement. The apparatus is cumbersome and if at all accurate, expensive. Like any other ap- paratus it requires some skill to use it with success. Any one who has either cast or rolled wax plates will not need a statement of the inconveniences. In 1905, it occurred to me that sheets of blotting paper might serve instead of wax plates. A small model was at once made which showed its feasibility. Models made of this material were demonstrated at thc Association of American Anatomists in December, 1905, ( Amer. Jour. Anat. V., 1905-06, p. XXIII) and the method was further demonstrated at the International Zoological Congress held in Boston, August, 1907'. It has also been used successfully in the embryologic and anatomic laboratories of Cornell University and the University of West Virginia. Blotting paper models were demonstrated by Dr. J. H. Hathaway and by Dr. J. B. Johnston at the Association of American Anatomists held in New York, 1906 (Proc. Assoc. Amer. Anatomists, Anat. Record, April 1, 1907,).
