Miller beer bottle packaging

Miller Brewer's flask packaging uses a variety of pressure-sensitive label technology, the new beer bottle features a limited sale of luminous labels. The label is printed with UV-sensitive ink that shines under ultraviolet light in darkened bars and nightclubs to attract consumers' attention. The front label is 2 μm thick biaxial polypropylene with sensitized emulsion on the 1 μm thick PET (polyethylene terephthalate) edge. The label on the back is a double-layer white BOPP and a UV two-color flexo-printed bottom layer plus a layer of cationic varnish (the varnish releases an acid when exposed to UV light, thus eliminating UV light). The surface layer is also UV two-color flexo plus varnish.
