    摘要： Purpose: The present invention provides a multi-layer film comprising a polyolefin film, an aluminum foil and a polyamide layer which are laminated sequentially, wherein the aluminum foil is adhered directly to the polyolefin film without any anchor coat agent or adhesive and the multi-layer film is excellent in adhesion strength between the polyolefin film and the aluminum foil and in low-temperature resistance.The multi-layer film according to the present invention comprises an aluminum layer (B) subjected to chromium-free chemical conversion treatment, a polyolefin resin film (A) on one side of the layer (B) and a polyamide layer (C) on the other side of the layer (B), wherein the film (A) comprises a layer (A-1) composed of an acid-modified polyethylene resin (α) and a layer (A-2) composed of a crystalline polyethylene resin (β), a temperature at which the acid-modified polyethylene resin (α) has a crystallinity of 60%, Tmα60, is lower than a temperature at which the crystalline polyethylene resin (β) has a crystallinity of 60%, Tmβ60, and the layer (B) is present directly on the layer (A-1).

    摘要： The present invention provides a wrap film or shrink film formed from a resin composition containing [I] a propylene polymer in an amount of 1 to 99 mass %, and [II] an olefin-based polymer in an amount of 99 to 1 mass %, wherein [I] the propylene polymer satisfies the following requirements of: (1) a meso pentad fraction (mmmm) is 0.2 to 0.6, and (2) a racemic pentad fraction (rrrr) and (1−mmmm) satisfy the following relation: [rrrr/(1−mmmm)]≦0.1. The wrap film or shrink film exhibits excellent characteristics, and does not generate a toxic gas derived from chlorine, such as hydrogen chloride gas or dioxin, when being incinerated.
