Abstract: PROBLEM TO BE SOLVED: To obtain a biaxially oriented polyester film having excellent molding fabrication property, shock resistance and beauty in appearance, and suitable as a material for molding fabrication by using a polyester having a melting point in a specific range as the main constituting component, and specifying the breaking elongations in the longitudinal direction and the lateral direction so that they satisfy a specific relation. SOLUTION: The objective film is obtained by using a polyester having a melting point of 210-280 deg.C as the main constituting component, and specifying the breaking elongation (%) in the longitudinal direction and that (%) in the lateral direction so that the following relation is satisfied (S1+S2)/2>=300%, here S1 and S2 are the values of the breaking elongation in the longitudinal direction and that in the lateral direction, respectively, when their sum becomes maximum determined at 20 deg.C to (melting point-60) deg.C. The film is fabricated by itself or in a laminar constitution with a nonmetal material (e.g. nonwoven fabric). The polyester is preferably obtained by polycondensing a dicarboxylic acid component (e.g. terephthalic acid) and a glycol component (e.g. ethylene glycol), and its intrinsic viscosity is preferably 0.5-1.5 g/dl.

Abstract: PROBLEM TO BE SOLVED: To facilitate separation/recovery while enabling recycling by forming a laminate from a layer partially or wholly dissolvable at a time of the treatment and a polymer layer separable and recoverable from the dissolvable layer. SOLUTION: A laminate is formed from a layer partially or wholly dissolvable by the treatment with an acid or alkali aq.soln. and a separable and recoverable polymer layer different in solubility from the dissolvable layer. As the aq.soln., an acidic aq.soln. and an alkaline aq.soln. can be designated and the temp. thereof is pref. 0-200 deg.C in usual. As a material constituting the partially or wholly dissolvable layer, a resin based on polylactic acid is especially pref. and the content of polylactic acid is set to 5-100 wt. %. The mol.wt. holding ratio of the polymer layer after immersed in a 1N sodium hydroxide aq.soln. at 25 deg.C is pref. 50% or more and, for example, a thermoplastic resin such as a polyester resin, a polyolefin resin, a polyvinyl chloride resin or a polystyrene resin is used for the polymer layer.
