Packaging materials classification

The 10 volumes in the Series on characterization of particular materials classes include volumes on silicon processir, metals and alloys, catalytic materials, integrated circuit packaging, etc. Characterization is approached from the materials user s point of view. Thus, in general, the format is based on properties, processing steps, materials classification, etc., rather than on a technique. The emphasis of all volumes is on surfaces, interfaces, and thin films, but the emphasis varies depending on the relative importance of these areas for the materials class concerned. Appendixes in each volume reproduce the relevant one-page summaries from the Encyclopedia and provide longer summaries for any techniques referred to that are not covered in the Encyclopedia. 

At ANCDF, packaging materials such as wood crates and metal containers that were used for storage of chemical agent munitions are not handled as a hazardous waste unless there is reason to believe liquid has leaked from the chemical agent munitions and the packaging container has come into contact with agent. If deemed necessary, headspace sampling and analysis is performed for proper classification. Uncontaminated... 

DOT CLASSIFICATION 8 Label Corrosive SAFETY PROFILE Poison by intraperitoneal route. Moderately toxic by ingestion. A human skin irritant. A corrosive irritant to skin, eyes, and mucous membranes. A substance that migrates to food from packaging materials. Violent or explosive reactions with chlorine, metal nitrates + heat, metal nitrites + heat, fuming HNO3. When heated to decomposition it emits very toxic fumes of SOx and NOx. See also SULFONATES.

Products for outdoor use such as wall cladding, can be press moulded in many variants from SMC or BMC. Pultruded profiles can also achieve B1 fire status if a resin such as DCPD or unsaturated polyester/MMA is used with up to 250 phr of ATH as part of the additive package. The classification of flame resistant GRP systems in the SBI test will be a great boost for the materials enabling them to satisfy the fire protection rules of the future. 

Acrolein is a DOT Flammable Liquid having subsidiary DOT hazard classifications of Poison B and Corrosive Material. It is also an inhalation hazard that falls under the special packaging requirements of 49 CER 173.3a. 

MIR techniques have simplified obtaining infrared spectra of many materials important in packaging. These include rubber, plastics, laminations, and components of these materials that find use in pumps, sample packages, and devices. The combination of MIR and computerized pattern recognition techniques can be used for differentiating and classification of flexible packaging polymers such as polyvinyl chloride (PVC), polyvinylidene chloride (PVdC), acrylonitrile (Barex), and CTFE (Aclar) [22]. 

It is presumed that the product(s) to be produced is (are) known. The size of the containers it will be shipped in depends on the size of the expected orders, the facilities the customer has for handling the materials, and the hazardous classification of the material. Material shipped in bulk quantity is cheaper than packaged items, but it requires the customer to have more elaborate unloading and storage facilities. Bulk shipping is only used when large amounts are purchased at one time. Union Carbide will not ship in bulk less than 40,000 lb (18,000 kg) of material. Table 3-2 gives a summary of the maximum bulk shipments possible by various carriers. 

A description is given of the initiatives carried out within the European Community for the harmonization of fire testing. The technical and economic reasons are explained for such initiatives, which are taken in order to remove barriers to trade from the European internal market. Of the various fire aspects, only fire reaction testing is taken into consideration here, because it appears as a major technical obstacle to the free circulation of construction materials. All possible approaches are considered for the attainment of such a harmonization and one, the so called interim solution, is fully described. The proposed interim solution, is based on the adoption of three fundamental test methods, i.e. the British "Surface Spread of Flame", the French "Epiradiateur" and the German "Brandschacht", and on the use of a rather complicated "transposition document", which should allow to derive most of the national classifications from the three test package. 

Packaging components for pharmaceuticals are basically made of glass and polymeric materials such as plastics and rubbers.1 In spite of this simple classification, glass, plastic, and rubber are not elementary materials but rather complex mixtures. 

Some bromine compounds are covered specifically under Hazardous Materials Regulations. Other compounds may usually be shipped under the classification of chemicals, not otherwise indexed by name, without special requirements unless from their nature they would fall under a category such as combustible liquid, compressed gas, corrosive liquid (or solid), disinfectant liquid (or solid), dmg, dye intermediate (liquid), fire extinguisher, flammable gas (liquid or solid), insecticide, medicine, oxidizer or oxidizing material, poisonous liquid (gas or solid), solvent, or tear gas. Specific provisions apply to each of these categories and appropriate packaging and labeling are required. 

Potassium compounds listed as hazardous substances by the U.S. EPA are given in Table 17. The U.S. Department of Transportation (DOT) maintains a Hazardous Materials Table that designates the listed materials as hazardous for the purpose of transportation, packaging, and labeling (50). Potassium compound DOT hazard classifications are also listed in Table 17. 

Operations dealing with hazardous materials involve storage, and transport. Space does not permit a detailed account of the topic, except to outline some aspects.10 Some aspects of transportation of hazardous materials consist of regulatory control, classification, packaging and labelling, transport containers, hazards and hazard assessment as well as emergency planning. 

The other validation test that is used to approve containers for use with sensitive preparations is the moisture permeability test. This evaluation is notably more complex in that it sets permeation limits based both on the type of container and the classification of the material being stored within. In general, these tests measure the performance of the packaging system but offer no design guidance. For compendial applications, permeability testing of plastics are described in the USP general chapters (661) and (671) for all types of containers.
