Review of Volatile Organic Compounds Derived From Polyethylene

Abstract: The formation of volatile organic compounds (VOCs) in polyethylene (PE) is a topic of concern to industries involved in the packaging of items such as foodstuffs and pharmaceuticals that are sensitive to organoleptic contamination. This article reviews the available literature on VOCs that originate from PE during its manufacture, processing, storage, and service life. The package-product interactions that may occur between PE and packaged foodstuffs are also considered together with the wide range of methods … Show more

“…Analytical methods for VOC analysis comprise: (i) sensory evaluation; (ii) chromatographic techniques and their associated sampling methods, including the "hot-jar" method and dynamic headspace sampling; (iii) gas chromatography-olfactory sensing; and (iv) artificial olfaction or "electronic nose" technology [22]. Sampling is the single most critical step also in odour problem solving as it conditions all the subsequent steps of the investigation.…”

“…In most cases, these compounds occurred at concentrations that did not produce measurable peaks in the GC-MS total ion current plots and so would not have been normally detected. A review of VOCs originating from PE by thermal oxidation, irradiation, storage, handling and package-product interactions has appeared [22]. The source of undesirable VOCs is not always related to the polymer, but may also be associated with additives, contamination from repeat-use containers, cross-contamination from storage silos, etc.…”

“…A great number of releasable compounds, especially from polyolefin, can be originated during different phases of the processing of plastic materials, for instance film extrusion, blow or injection moulding, thermoforming, sealing and corona treatment. In fact, heating the polymer induces a thermal oxidation that leads to the production of odorous volatile organic compounds (Hodgson et al, 2000). The presence and the effect of these migrating into packaged foods is commonly assessed by instrumental and sensory techniques.…”

“…Many authors have in fact demonstrated the effectiveness of the e-nose in odour evaluation of packaging materials such as paper (Holmberg et al 1995), paperboard (Ljungberg Willing et al 1998) and plastic films (Frank et al 2001;Van Deventer and Mallikarjunan 2002) and in the determination of sensory contamination of packaged foodstuffs (Heiniö and Ahvenainen 2002). Nevertheless, only few studies that have appeared in literature have focussed on the odour of polymers in pellet form (Hodgson et al 2000). However, a study performed on plastic resin could provide useful information for defining the material sensory requirements in the supply contract in order to reduce possible litigation between producers and converters.…”

“…Xenobiotic VOCs, which include alkanes, aromatic hydrocarbons, and halogenides, are not produced by biodegradation and are usually inherent in household wastes such as plastic packaging, waste cooking oil, and pesticides on fruits and vegetables (Hodgson et al, 2000;Komilis et al, 2004;Sohelili et al, 2002). Xenobiotic VOCs can be volatized from MSW and usually persist in the exhausted air during the aerobic biological process (Scaglia et al, 2011).…”
