    1. Screening for Chemicals in Paper and Board Packaging for Food Use: Chemometric Approach and Estimation of Migration (pages 385–395)

      An analytical survey on paper and board materials intended for food use was carried out by means of solvent extraction with subsequent analysis by gas chromatography/mass spectrometry. Principal component analysis was used to explore the data. It allowed to identify and select some compounds as markers for sample classification. Additionally, the semi-quantification of the compounds in the packaging allowed a worst case estimation of food contamination by means of the infinite total migration model; occasionally, migration estimations overcame the specific migration limits.

    2. Towards a Conceptual Sustainable Packaging Development Model: A Corrugated Box Case Study (pages 397–413)

      The study presents a unique integrated model of most relevant agents related to the design and implementation of a corrugated packaging through a supply chain from design to post-consumer and reuse. The research enlightens how small efforts can reduce CO2 emissions and waste, through four ex ante design stages and two ex post facto supply chain stages. Further, the research integrates the design criterion for a unit load and creates opportunity to observe the packaging system holistically.

    3. Effect of Pasteurization and Retort Processing on Spectral Characteristics, Morphological, Thermal, Physico-Mechanical, Barrier and Optical Properties of Nylon-Based Food Packaging Materials (pages 425–436)

      The results show that WVTR and OTR of nylon-based packaging materials increased, and this increase is higher with severity of heat treatment. This could be attributed to the fact that N6 can form hydrogen bonding in the presence of high moisture environment, small crystal formation as a result of heat processing.

    1. Maximum Gauge Pressure in Dangerous Goods Packagings Under Normal Conditions of Carriage – Comparison of Direct Measurement and Calculation (pages 437–460)

      The objective of this work was to determine the maximum gauge pressure in the vapour phase above the liquid in different design types of dangerous goods packagings under normal conditions of carriage. The volume of the design types was approximately 6 l. Two different methods were compared: direct measurement, using dichloromethane as test liquid, and calculation, using a packaging-specific relative expansion function. The results showed that the calculation method provides conservative results for the gauge pressure.

    2. Determination of Four Types of Hazardous Chemicals in Food Contact Materials by UHPLC-MS/MS (pages 461–474)

      An UHPLC-MS/MS method for the identification and quantification of two photoinitiators, nine plasticizers, three primary aromatic amines and six bisphenols in food contact materials has been developed. Under optimised conditions, the chromatographic separation was performed in 12 min. The optimised method was successfully applied to trace analysis of the four classes of hazardous chemicals in commercially available food contact materials.
