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).
