“…Industrial norms allow up to 12% deviation from standard oxygen and water barrier levels [34]. For developing shelfstable products to be stored above room temperature, the US army has specified a 0.06 mL/m 2 /day oxygen permeability limit and a 0.01 g/m 2 /day water permeability limit.…”

“…On the other hand, some commercial shelf-stable products require an oxygen permeability value between 0.1 and 0.2 mL/m 2 /day. Retort pouches generally carry a middle Al layer (e.g., 7, 9, and [33,34]. Headspace requirement as per Japanese standard b Venugopal [60] c EU 90/128…”

“…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]. Physical strength must be high enough to provide the mechanical strength (puncture resistance) to withstand handling during manufacturing and distribution.…”

“…A maximum headspace of 30% has been recommended [33]. Typically an HPP vessel will utilize its 50-70% volume capacity depending on the shape of the package and the vessel design [34]. If the HPP process requires preheating of the food product, the highest possible thermal conductivity is desirable for the material.…”

“…In-container processing requires packages in form of pouches, large bulk bags, or container-lid combination. According to Lambert et al [34], 90% of HPP-processed foods are processed in flexible or partially rigid packages. Figure 1 shows examples of commercial polymeric bottles, trays, and multilayer pouches currently utilized in industry.…”

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.
