Abstract
The disclosed relates to a polyalkylene carbonate-based resin film. More specifically, the present disclosure relates to a polyalkylene carbonate resin-based film comprising a blend resin in which a polyalkylene carbonate resin and a polyketone resin are mixed in a specified amount, thereby ensuring both excellent tensile strength and tear strength without deteriorating elongation properties possessed by the polyalkylene carbonate resin.
Claims12
A polyalkylene carbonate-based film comprising:
- a blend resin in which 75 to 99% by weight of a polyalkylene carbonate resin and 1 to 25% by weight of a polyketone resin are mixed,
- wherein the polyalkylene carbonate-based film has a tensile strength of 200 kgf/cm2 to 300 kgf/cm2 as measured by ASTM D 638, and
- wherein the polyalkylene carbonate resin includes a repeating unit represented by Chemical Formula 1:
- wherein, in Chemical Formula 1, R1 to R4 are each independently hydrogen, a linear or branched alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms or a cycloalkyl group having 3 to 20 carbon atoms, at least two of R1 to R4 may be connected to each other to form a cycloalkyl group having 3 to 10 carbon atoms, and m is an integer of 10 to 1,000.
