ABSTRACT:
Antimicrobial and antifogging polymeric films with preferable A/C/E structure useful for the food, medicine and agriculture applications as well as for other general packaging and non-traditional special applications. More preferably, antimicrobial and antifogging films having a A/B/C/E structure. Most preferably, antimicrobial and antifogging films having a A/B/C/D/E structure. A multilayer structure (having at least an skin layer (A) having antifogging and antimicrobial properties/a core layer (C)/an outer layer (E) structure) for semi and biaxially oriented polyolefin based antifogging films having advantageous properties as compared with known and commercial films such as low values of haze, high values of sheen, lower longitudinal and transverse shrinkage, which provides high dimensional stability, and excellent antifogging and antimicrobial properties. Preferably the skin layer (A), having antifogging and antimicrobial properties, is electrical corona or flame treated. Electrical corona or flame treatment of the outer layer (E) may enhance ink anchorage and increase the printability of this layer. Preferably, the films comprise an inner (B) layer between the skin layer (A) and the core layer (C). Preferably, the films may comprise a second inner (D) layer between the outer (E) layer and the core layer (C).
