According to FAO data, every year 1.300 million tons of food are wasted, which is equivalent specifically to a third of their world production, with the associated social, environmental and economic problems. One of the main strategies to avoid the waste of food is to extend the shelf life of products by packaging them with materials with barrier properties, generally materials with multilayer structures (eg PET / PE, PET / EVOH / PE, OPP / OPP, PET / met / PE, etc).

The selection of the type of packaging material is crucial for the conservation of the products during their distribution, as well as for other purposes such as using solutions of low weight and with adequate mechanical properties, which has caused the sector of rigid and flexible plastic packaging, occupies around 40% of the market for food packaging. However, these multilayer packaging systems usually have a high manufacturing cost (due to the necessity of different coextrusion and lamination processes) and are difficult to sort and recycle (heterogeneous waste, different melting points, similar densities, etc.).

 

Additionally, in recent years a legislative framework has been developed with a high level of demand and activity that regulates the generation and management of packaging, both at European, national and even regional levels. Specifically...READING MORE AT https://www.infopack.es/revista/268/#page/47
