The primary appHcation for barrier polymers is food and beverage packaging. Barrier polymers protect food from environmental factors that could compromise both taste and shelf life. They also help retain desirable flavors and aroma. Barrier polymers are also used for packaging medical products, agricultural products, cosmetics, and electronic components and in moldings, pipe, and tubing. 

High Nitrile Copolymers for Food and Beverage Packaging... 

Random copolymers of acrylonitrile and styrene containing less than 30% AN have been well known (11), and many varieties have been sold commercially. The generic material known as SAN, which is a copolymer of 25% AN and 75% styrene, has been sold for many years but has not been used in food or beverage packaging because of its relatively poor barrier and organoleptic properties. There was little or no interest in... 

These results, considered in relation to the direct addition tests of monomer and hydrogen cyanide in the previous table, demonstrate that there is no reason to expect styrene monomer extraction into soft drinks, even at levels well below those we can measure analytically. They also reinforce our hydrogen cyanide data. Further, they indicate that these beverages are not more extractive of Lopac containers than the normal simulating solvents. The tests confirm the chemical safety of the containers as beverage packages. 

Our studies of the absorption, permeation, and extraction properties of containers produced from high nitrile barrier resins have demonstrated that they meet or surpass the basic criteria established for retention of taste and odor characteristics of carbonated soft drinks. Sensory tests, which can isolate and identify end results as well as integrate collective effects, have confirmed this judgement and have established the general compatibility of these containers with a variety of beverage products from a taste and odor standpoint. Furthermore, these materials have the excellent physical properties required for containers which will find wide use in food and beverage packaging. 

Major types of volatile constituents in polymers include unreacted monomers, nonpolymerisable components of the original charge stock, residual polymerisation solvents, and water. Frequently, complex nonpolymerisable mixtures are present. The concentration of these substances may need to be determined for various reasons, such as the effects on materials properties and the risk of tainting in foodstuff- and beverage-packaging grades. For this purpose various GC methods are in regular use ...

Many materials used for food and beverage packaging have characteristic odors or sensory active compounds (Torri et ah, 2008). The intensity and description of the odor may be affected by the number and type of volatile compounds that are released under environmental conditions at the time of evaluation. Chemical composition of the material and polymer morphology may play a role in the sensory characterization. Sensory descriptors do not define a specific chemical compound but may be related to different compounds, a blend of compounds, and even a limited concentration range of a compound or class of compounds. For example, frans-2-nonenal in water changes in sensory (taste) description from "plastic (0.2 gg/1) to "woody" (0.4-2.0 p.g/1), "fatty" (8-40 pg/1), and "cucumber" (1000 gg/1) (Piringer and Ruter, 2000). Such terms are descriptive of the sensation and perception by human response to the chemical stimuli (Table 2.1).

Beverage Packaging Consumer Goods Packaging Aluminum Steel Cans Glass Containers... 

Cans may either be three piece consisting of a body made up of a welded cylinder with one end seamed in place which is then closed with a second end, or two piece consisting of a body formed from a single piece of metal closed with an end (see Fig. 11.1). Aluminium cans are always two piece whereas steel cans may be either three piece or two piece . The end or ends are seamed onto the can body which involves the forming of a double seam of folded metal (see Fig. 11.2). A hermetic seal (a key element of metal food and beverage packaging) is ensured by the incorporation of a... 

Metal packaging for food and beverage has particular features that differentiate it from other food packaging materials and which also influence the management of overall food safety and regulatory compliance. These features differ in some aspects between food and beverage packaging.
