Flexible packaging based on paper, plastics, or aluminium is extremely popular in all global markets, its consumption has shown an upward trend. Their advantages include low weight and high barrier product protection, especially against moisture, abrasion, wear, grease, vapor permeability or loss of aroma. Moreover, thin films are mostly resistant not only to water but also to solvents plus they are heat-sealable and therefore easily processed into different types of packaging. Such packaging is easy to print on. Unlike with rigid materials, there is not an emphasis on demanding package structure.
