After packaging boxes were printed, most of them will be coated with laminated or varnished finishing. and they will have glossy or matte effect.
Both of laminated and varnished finishing will protect the printing color from fading and let the boxes to be waterproof. The one thing need to mentioned is that the laminated finishing is actually using plastic film coated on paper, while varnished is just oliy film mounted on box surface, from this aspect, varnished is wearker protection to the box but is more envirmental than laminated.
