Laminated Materials: We are proud to offer two materials that are exclusive to Madeline Blondman & Co. Working closely with our engineers and material suppliers, we have formulated two materials that provide excellent moisture and resistance barriers. We have developed a process in which we laminate a .001 gauge layer of resistant polypropylene to either .007 gauge white PVC or .0075 gauge white PETG. For those customers requiring the additional barrier protection of Polypropylene, and cannot use PVC, the PETG/PP laminate is a superior choice.
