The invention provides a laminated film with excellent bag rupture resistance, bending resistance, and gas barrier properties before and after bag producing processing or even when a bag produced from the laminated film is used for packaging of hard contents or subjected to a harsh wet-heat treatment such as retort sterilization. The laminated film comprises an inorganic thin film layer and a protective layer in this order on a base film layer, wherein the base film layer contains a resin composition containing 60% by mass or more of a polybutylene terephthalate and has a thermal shrinkage at 150 C. of 4.0% or less both in a longitudinal direction and a width direction of the base film layer and a dimensional change rate at 200 C. with respect to an original length of the film of 2% or less in a temperature-dimensional change curve in a longitudinal direction of the base film layer.

The present invention concerns a chemical mechanical polishing pad having a polishing layer that possesses a consistent positive zeta potential across the entire surface. Also disclosed is a chemical mechanical polishing method using the polishing pad together with a positively charged slurry.

A method of recycling polyurethane foam scrap by recovering polyols from the polyurethane foam scrap using a glycolysis/transesterification process, reacting methylene diphenyl isocyanate (MDI) with virgin polyol and recycled polyol to make a prepolymer with recycled content, and mixing the prepolymer with recycled content with 4,4-methylenediphenyl diisocyanate, isocyanic acid, polymethylenepolyphenylene ester, and di-phenylnethane-2,4-diisocyanate to form a MDI prepolymer blend with recycled content, and using the MDI prepolymer blend with recycled content for production of polyurethane foam components having an amount of recycled polyurethane content. Optionally, the MDI prepolymer with recycled content is used during the same foam production process that generated the foam scrap used to recover the recycled polyol.
