Historically labels were always made on paper, although over the past few years OPP labels have entered the market quite strongly, especially in sectors such as bottled water, soft drinks in PET bottles, canned food or household products (all-purpose cleaners, fabric softeners, detergents, etc.).
First, we would like to define what an OPP label is for those of you who are not yet familiar with them. OPP are the initials of a material called Oriented Polypropylene. We can find transparent OPP or white OPP, also known as opaque . The main differences between these two apart from their aspect are their thicknesses and their weight in gr/m2.
In transparent OPP we are talking about thicknesses between 30 and 50 microns depending on the finish, roll or pre-cut. And in white OPP this is between 38 and 65 microns. These thicknesses are for labels; there are other thicknesses, but these are used for flexible packaging.
