Provided is a polyamide-based composite resin composition which includes 30 to 80 wt % of a polyamide-based resin; 5 to 59 wt % of m-xylenediamine (MXD)-based modified nylon; 10 to 50 wt % of thermoplastic olefin rubber including a maleic anhydride-grafted ethylene-octene copolymer, a maleic anhydride-grafted ethylene-propylene-diene monomer, or a mixture thereof; 0.5 to 10 wt % of clay; and 0.01 to 5 wt % of carbon nanotubes (CNTs). According to the present invention, the polyamide-based composite resin composition is easily subjected to blow molding, is excellent in mechanical properties such as low-temperature impact strength and tensile strength, and is also capable of significantly enhancing a gas barrier property.

A sealing composition for use in unit dose packages is provided, including: 70 to 98 wt % water; 1 to 30 wt % of a hydrogen bonding component; and 1 to 30 wt % of a complex forming component.

Separation of linear and branched alkane isomers via selective permeation through a composite membrane is disclosed. The separation layer in the composite membrane is fabricated from a blend of at least two different fluoropolymer compositions, A and B, in which composition A has a normal-alkane isomer permeability that is greater than composition B. Composition B has a normal alkane to branched-alkane isomer selectivity that is equal or greater than composition A. The separation layer in the composite membrane has a normal-alkane permeability that is greater than composition B and a normal-alkane to branched alkane isomer selectivity that is greater than composition A.
