Polycarbonate compositions include: (a) from about 45 wt % to about 90 wt % of a polycarbonate homopolymer; (b) from about 1 wt % to about 25 wt % of a polycarbonate copolymer; (c) from about 0.1 wt % to about 20 wt % of a first flame retardant component including a brominated flame retardant; (d) from about 0.01 wt % to about 1 wt % of a second flame retardant component including an alkyl sulfonate salt, an aromatic sulfone sulfonate, an aromatic sulfonate salt, or a combination thereof; and (e) from about 0.1 wt % to about 20 wt % of a siloxane-free acrylic core-shell impact modifier. The combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition.

High comparative tracking index polycarbonate compositions with improved flame retardant and hydro-stability properties

A film, preferably, a multi-layered film, including a polymer composition, wherein the polymer composition includes: within a range from 1 wt % to 25 wt % of a cyclic olefin copolymer based on the weight of the polymer composition, and within a range from 75 wt % to 99 wt % (the remainder of material) of a polyethylene based on the weight of the polymer composition, wherein the cyclic olefin copolymer has a glass transition temperature (T.sub.g) of at least 80.degree. C. The films may be used in shrink packaging application.
