Summary. The use of polypropylene materials in industry for food packaging is increasing. The presence of additives in the polymer matrix enables the modification or improvement of the properties and performance of the polymer, but these additives are potential risk for human health. In this context, an efficient analytical method for the quantitative determination of three antioxidants (2,6-di-tert-butyl-4-methylphenol (BHT), dibutylhydroxyphenylpropionic acid stearyl ester (Irganox 1076), and tns-(2.4-ditert-butyl)-phosphite (Irgafos 168)) and five ultraviolet stabilizers (2-(2′-hydroxy-5′-methylphenyl) (UV-P), (2′-hydroxy-3′-tert-5′-methylphenyl)-5-chloroben zotriazole (UV-326), 2-(2′-hydroxy-3′,5′-di-tert-butylphenyl)-5-chlorobenzotriazole (UV-327), 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol(UV-329), and 2-hydroxy-4(octyloxy) benzophenone (UV-531)) in polypropylene food packaging and food simulants by high-performance liquid chromatography (HPLC) has been developed. Parameters affecting the efficiency in the process such as extraction and chromatographic condition were studied in order to determine operating conditions. The analytical method showed good linearity, presenting correlation coefficients (R ≥ 0.9977) for all additives. The limits of detection and quantification were between 0.03 and 0.30 μg mL −1 and between 0.10 and 1.00 μg mL −1 for eight analytes, respectively. Average spiked recoveries in blank polypropylene packaging and food simulants were in the range of 80.4-99.5% and 75.2-106.7%, with relative standard deviations in the range of 0.9-9.1% and 0.2-9.8%. Dissolving the polypropylene food packaging with toluene and precipitating by methanol was demonstrated more effective than ultrasonic extract with acetonitrile or dichloromethane for extracting the additives. The method was successfully applied to commercial polypropylene packaging determination, Irgafos 168 and UV-P were frequently found in six commercial polypropylene films, and the content ranged from 166.47 ± 5.11 to 845.27 ± 29.31 μg g −1 and 2.10 ± 0.29 to 19.23 ± 1.26 μg g −1 , respectively.

“…Meanwhile, polymeric food packagings are not inert and migration of additives or their degradation products from packaging to food is a wellknown issue, covered by European Commission (EC) regulation related to food contact materials [1][2][3]. Moreover, during their lifecycle or first use, substances can penetrate into polymer packagings especially with polyolefins.…”

“…), the main disadvantage of these materials is interaction with the product. Interaction between packaging and product has been widely studied, 1,2 as the transfer of additives, 3,4 monomers, 5 adhesive compounds, etc. to products is a matter of great concern, especially when food products are packed.…”

Determination of cosmetic ingredients causing extrusion‐coated and adhesive joint multilayer packaging delamination

In order to study the effect of several compounds on packaging stability, different cosmetic ingredients at two concentration levels were added to a NeoPCL® (Acofarma, Terrassa, Spain) water emulsion, and the preparations packed in sachets and stored at 40°C during 3 months. After that, the packaging was subjected to a T-peel test and headspace solid-phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) analysis. The HS-SPME-GC-MS analyses were performed using a 75 mm carboxen polydimethylsiloxane fi bre to check for the presence of the studied analytes in the inner layers. The study revealed that the presence of a phenyl and a hydroxyl group in the compound structure lead to an important loss of adhesion between packaging layers joined by an adhesive. The interaction between the cosmetic ingredient and the adhesive was proposed as the main cause of the loss of adhesion. However, extrusion-coating packaging was more susceptible to delamination, particularly with the volatile compounds.
