Fiber packaging grades

Fig. 4.59 Fiber preparation system for packaging grades without fractionation (source Voith).

The salt is packaged ia 45-kg multiwaH bags or fiber dmms of 45, 170, or 181 kg. It is available ia both powdered and granular forms with densities of 1.04 and 1.44 g/cm (65 and 90 lb/fT), respectively. Only the powdered grade is authorized by and registered with the EPA for use ia pesticide formulations, with the further proviso that it must be tinted blue or green, or otherwise discolored. The word poison appears on all labels together with first-aid information. 

Electronic-Grade MMCs. Metal-matrix composites can be tailored to have optimal thermal and physical properties to meet requirements of electronic packaging systems, eg, cotes, substrates, carriers, and housings. A controUed thermal expansion space tmss, ie, one having a high precision dimensional tolerance in space environment, was developed from a carbon fiber (pitch-based)/Al composite. Continuous boron fiber-reinforced aluminum composites made by diffusion bonding have been used as heat sinks in chip carrier multilayer boards. 

In addition, many grades of paper and paperboard are used in direct or indirect contact with foods. Thus, many mills only use paper chemicals that have been cleared for use by the U.S. Pood and Dmg Administration (PDA) (3), so that it is not necessary to segregate machine broke (off-grade paper and edge clippings that are reclaimed for their fiber value) and white water. Most of the chemicals discussed in this article are approved by the PDA for use in paper and paperboard that are intended for appHcations in food processing and packaging. However, there are various restrictions on both the specific functional uses and amounts of paper chemical additives which can be used, so the PDA status should be confirmed by the suppHer before use. 

Seismograph-Grade Explosives for use in seismic prospecting on land and offshore. Various grades are available in diameters from 2 to 8 inches packaged in fiber cartridges, metal cans, or plastic ... 

Application E PTA (Eastman polymer-grade terephthalic acid) is an excellent raw material for engineering plastics and packaging materials, bottles, other food containers including hot fill, as well as films. The process is proven to be suitable for the production of all kinds of polyester fibers and containers without limitation, at international first-grade quality. 

Application Production of polymer-grade terephthalic acid (MTA). MTA is an excellent raw material to produce polyethylene tereph-thalate resin (PET), which is used for engineering plastics, packaging materials—like bottles and other food containers—as well as films. Also, integrated polyester producers use MTA to make various types of fibers. 

LAURYL PYRIDININUM CHLORIDE, technical grade, is a mottled, tan waxy solid packaged as a solidified melt in fiber drums. It is soluble in water, alcohol, glycols, acetone, and other organic solvents. 

The current study provides a new type of edible, antimicrobial food packaging or wrapping films from food-grade natural fibers or hydrocolloid. Besides film casting, the films can also be produced by compression, extrusion blown methods. The inclusion of PEO hydrocolloid in natural fiber formulations makes films tougher and caused less permanent deformation when the films were subjected to an external force. Since the extrusion and compression were performed in mild conditions, nisin can be incorporated into films without diminishing its antimicrobial activity. 

The brown coir fibers may receive several additional preparatory treatments, specific to the anticipated end-use, before they are graded, packaged, and shipped or exported.
