    摘要: A polyethylene composition suitable for use in a living hinge component, the composition comprising a first ethylene-based polymer component, wherein the first ethylene-based polymer component has a density of from 0.940 g/cc to less than 0.960 g/cc, a melt index, I2.16, of less than 0.5 g/10 min, and a weight average molecular weight, Mw,cc, as measured by gel permeation chromatography using conventional calibration, of greater than or equal to 200,000 g/mol, and a second ethylene-based polymer component, wherein the composition has an overall density of from 0.945 g/cc to 0.960 g/cc and an overall melt index, I2.16, of from 10 g/10 min to 70 g/10 min.

    摘要: Provided is a film for packaging chemicals which does not change in appearance (e.g. yellowing), or does not generate odor, even after long-term storage; which is prevented from being scratched or contaminating rolls when the film is drawn from a roll thereof; and which expresses excellent chemical resistance. Also provided is a film for packaging chemicals which is easily detachable from a heat seal plate when contents are packed and sealed therein. The film for packaging chemicals includes polyvinyl alcohol; and a surfactant, the amount of the surfactant being 0.9% to 5% by mass based on 100% by mass of the polyvinyl alcohol, the surfactant having a polyoxyethylene structure, the number of moles of oxyethylene groups in the surfactant being 5 to 13 mol, the surfactant having a HLB of 9 to 14.5.
