Disclosed herein is a resin composition including an ethylene-acrylic acid alkyl ester copolymer (L), a graft copolymer (M), and a styrene-based elastomer (N), wherein the graft copolymer (M) is obtained by a reaction among an ethylene-acrylic acid alkyl ester copolymer (A), a monomer component (B) containing at last one monomer selected from the group consisting of a (meth)acrylic acid alkyl ester monomer and an aromatic vinyl monomer, and t-butyl peroxymethacryloyloxyethyl carbonate (C), and a weight ratio between the ethylene-acrylic acid alkyl ester copolymer (A) and the monomer component (B) ((A)/(B)) is 50/50 to 98/2. The resin composition is capable of reducing squeaking noises generated by contact between a thermoplastic resin molded body and leather.

Provided is a thermoplastic resin composition which includes: a first graft copolymer including a C.sub.4 to C.sub.10 alkyl (meth)acrylate-based monomer unit, a C.sub.1 to C.sub.3 alkyl-substituted styrene-based monomer unit, and a vinyl cyan-based monomer unit; a second graft copolymer including a C.sub.4 to C.sub.10 alkyl (meth)acrylate-based monomer unit, an alkyl-unsubstituted styrene-based monomer unit, and a vinyl cyan-based monomer unit; a first styrene-based copolymer including a C.sub.1 to C.sub.3 alkyl-substituted styrene-based monomer unit and a vinyl cyan-based monomer unit; a second styrene-based copolymer including an alkyl-unsubstituted styrene-based monomer unit and a vinyl cyan-based monomer unit; and an olefin-based copolymer including a C.sub.1 to C.sub.3 alkyl (meth)acrylate-based monomer unit. The thermoplastic resin composition exhibits remarkably excellent chemical resistance and remarkably excellent appearance characteristics while maintaining basic properties.

Disclosed herein are various embodiments of a protective packaging system suitable for use with a prefinished building article. The protective packaging system generally is designed to reduce shrink back of the flexible substrate after tension is applied. The protective packaging system generally comprises at least one outer layer, at least one core layer and at least one adhesive layer. One or more layers of the protective packaging system may include a roughening agent such that the flexible substrate will not “gloss” or burnish a coating on a prefinished building article. The protective packaging system may also include one or more biocides.
