VISIBLE LIGHT BARRIER FOR DAIRY PACKAGING.

摘要

A package system having a body is described. The body has a bottom wall, at least one side wall, and a top wall cooperating with one another to define an interior compartment for housing a consumable product. At least one of the bottom wall, side wall or top wall includes a viewing portion having a light barrier configured to block wavelengths of visible light from below a baseline wavelength and above a top-�line wavelength and pass visible light between the baseline wavelength and the top-�line wavelength so as to allow the consumable product to be viewed through the viewing portion of the body.
