Holographic effects are usually achieved by laminating non-biodegradable PET to boxboard, which makes the package unrecyclable. PaperWorks, however, achieved an equivalent holographic effect by micro-embossing a common reflective coating to the boxboard. This process not only cost less to produce but also eliminated the need for the additional lamination step at an off-site facility, thus saving money on transportation, energy, and raw materials.
说的就是以折光凹凸来代替全息效果，降低成本，并且利于回收。
