In the MeetingPack exhibition area, we were also able to witness the first oxygen-barrier PVOH coating to be applied in the printing and lamination process of flexible structures, shown by Artibal, which has been developed within the COAT4PACK project in conjunction with ITC and Plásticos Romero. These new packages replace co-extruded EVOH structures. In particular, it has been achieved to reduce both the manufacturing process and the thickness of the multilayer barrier structure. For that purpose, oxygen barrier coatings have been developed to be applied by means of printing technologies that allow the lightening of the structures of food packages in comparison with the multilayer EVOH structures.
Lastly, AIMPLAS and AINIA introduced two projects in which they are participating. The NIASAFE project, focused on analysing, monitoring and minimising the migration of Non-Intentionally Added Substances (NIAS) to food-contact packaging. The REFUCOAT project, which is focused on developing new materials to package food in a more sustainable way. Within this project, barrier coatings are being developed, as well as bioplastics to be used in films and trays as an alternative to the current aluminium-based structures.
