this substantial progress was made possible by combining reifenhäuser&rsquos versatile 119channel evolution® barrier blown film technology and a new pet based dupont&trade appeel® sealant resin. compared to traditional lidding films with an additional ldpe sealing layer, which is coextruded or laminated to the apet structure, the use of a coextruded appeel® sealing layer provides superior packaging properties. trims can be directly recycled, the bottom web costs can be reduced by up to 40 percent and the total weight of the tray can be up to 15 percent lower without loss in stiffness.  the new lidding film for monoapet trays comes with a layer of a printable pa outside, which provides the heat resistance required for contact with the sealing bar. source httpwww.dupont.comindustriespackagingandprintingmediapressreleasesliddingfi…
