摘要： In an antifungal protective film having at least one layer and an acidifying polymer and a disulfite the at least one film layer includes fluid-filled bubbles or cells that are created by foaming. The cells created by foaming during the extrusion enable the generated sulfur dioxide to collect inside this film layer, thereby being buffered and achieving a long-term action releasing the antifungal sulfur dioxide. The film can have a single foamed layer containing the polymer and disulfite or such a layer sandwiched between two outer layers having different properties, all produced by coextrusion.

摘要： A tear-open packaging is formed by a pair of plastic film panels having inner faces joined together by a weld. One of the film panels is formed by a two- or three-layer coextrusion having a nonsticky foam core layer and a weldable inner layer that is secured by the weld directly to the inner face of the other film panel. The strength of the core layer and of the bond between the core layer and inner and outer layers are such that, when the two panels are pulled away from each other, the core layer or an interface between the core layer and the weldable inner layer will tear along the weld. If the weld does not extend directly to an edge of the film tear-open packaging, the weldable layer breaks on both sides of the weld.
