“…Only a combination of PET/PVDC/PA/HDPE/PP showed small wrinkles and signs of delamination or wear on the PP side after an 800 MPa and 45°C treatment [7]. The oxygen permeability in all PVDC-based materials remained within the original value.…”

“…These materials were not changed after HP-LT. The tensile strength of the PET/PVDC/EVA/LLDPE material [7] was reduced by 63% (outside the 25% industrial deviation). However, this composite provided a tensile strength comparable to the PET/PVDC/PE [37].…”

“…Furthermore, the elastic modulus and the percentage of elongation can assess the deformation of the package after processing [7]. Industrial norms suggest that deviations in tensile strength, elongation, elasticity modulus, as well as seal strength, must remain within the 25% range for these properties [34].…”

“…The two SiO x -based materials tested [7,15] showed visual integrity problems due to delamination (PP/SiO x ) or formation of small wrinkles on the food contact side (PET/ SiO x /PE). Oxygen and water permeability increased for the PET/SiO x /PE laminate.…”

High-pressure processing (HPP) of foods mainly utilizes flexible packaging materials for commercial products. Many materials have been evaluated for their adequacy in the process. There are a number of integrity requirements for these packaging materials that must be complied with for acceptance and use in different product applications. These include visual integrity, gas permeability, seal and physical strength properties, and global migration of packaging components into the food, some of which are specific to either refrigerated or shelf-stable products. Different laminate options reported in the literature were reviewed in this article with the aim of classifying suitable packaging materials for HPP at both lowand high-temperature conditions according to these requirements. Packaging materials currently utilized in industry are also listed. The suitability of standards to assess requirement deviations after HPP is also discussed. Current scientific literature has shown to lack information on one or more of these requirements to provide a complete picture for their suitability. Studies have shown that EVOH-based and other high-pressure-high-temperaturetreated materials do not follow the barrier requirements established by the US Army for shelf-stable products. However, they still show potential for their utilization in the development of commercial products. The importance of package headspace on package integrity is also highlighted. Studies on transport phenomena such as material sorption and diffusion of components from the food and the pressurization fluid are described. Methods such as SEM, C-SAM, DSC, FT-IR, and X-Ray diffraction provide complementary information to assess the structural and barrier changes observed during HPP. The article concludes by providing preliminary recommendations according to specific requirements that are met after the process. Other types of materials not yet evaluated for HPP are presented as potential alternatives to be explored for this technology.

“…Estudios previos han demostrado que los envases flexibles son más adecuados que los rígidos para los tratamientos con altas presiones. Los envases rígidos, tales como los botes metálicos o de vidrio tienden a fracturarse o deformarse como resultado de la elevada presión aplicada 24 . Por el contrario, la mayor parte de los envases flexibles soportan este tipo de tratamientos de conservación sin mostrar signos visibles de pérdida de integridad.…”
