Celplast Metallized Products recently co-presented a paper with Larry Jopko of Dow at the TAPPI Barrier Symposium at ICE in Orlando, FL, entitled “How good is your barrier packaging in the real world?” This paper focused on barrier properties and lamination bond strengths of 2 ply and 3 ply metallized film structures, both before and after gelbo flexing. Two different high barrier metallized films were examined: Barrier Sealant metallized PE and Metacoated PET. Three different adhesive systems were evaluated: solvent based, solventless and water based. The Barrier Sealant in a 2-ply structure, laminated to clear PET, gave the best performance in terms of retaining barrier properties after Gelbo flexing.
Celplast Metallized Products is a leading supplier of high barrier films to the North American converting industry, including SUPERMET™ and ULTRAMET™ for high metal adhesion, and FOILMET™ for high barrier. Celplast is also the exclusive distributor to North America of the CERAMIS® SiOx-coated and Camclear® AlOx-coated families of clear barrier films. Celplast has recently introduced a family of top-coated metallized films, with a top-coating designed to protect the metal layer from moisture and hot, humid environments. This includes REFLECT-MET™ for reflective insulation and radiant barrier applications, as well as DURA-MET™ for extended shelf life food packaging. Celplast also offers testing for OTR, WVTR, metal adhesion, emissivity, scuff resistance, corrosion resistance and benchtop laminating in its state-of-the-art R&D lab.
