Abstract
A sampler package for fluid cosmetics, creams, gels, and the like having a liquid solvent base includes a transparent composite laminate sealed with a composite laminate having a foil barrier layer. The sealed composite laminates form a pouch in which the cosmetic sample is contained. The transparent composite laminate is preferably adhesively laminated with either a biaxially oriented PVDC film or a polychlorotrifluoroethylene film as the moisture vapor barrier layer. The moisture permeability rate of the barrier film is at most 0.065 g/100 in,/24 hrs @100° F.,90% RH. Use of such transparent films as the barrier laminate permits the sampler package to be formed with a transparent window through which the color, texture, etc. of the sampler product may be viewed.
