PTFE Coated Fabric

Previously when a package was required to have a visible seal a porous Ptfe-glass fabric had to be used, the problem with this method was low ptfe-content which meant fewer seals before failure and the openings of the porous fabric eventually filled up with melted film.9070 fabrics are non-porous.A proprietary coating process allows for a generous amount of PTFE to be applied to the fabric while still allowing the natural texture of the fiberglass to come through, resulting in a long lasting product that embosses a readily visible pattern into the film.
