Abstract
A laminate resin film having two major surfaces is constituted by plural resin species. In the laminate, layers of the plural resin species are laminated obliquely to the two major surfaces in at least one section perpendicular to the two major surfaces, and each layer of the plural species of resins is exposed to the two major surfaces. The laminate resin film has equivalent properties in the thickness direction (such as gas-barrier property) as in a conventional laminated film but has properties in the planar extension direction which are remarkably affected by properties (such as low Young's modulus and heat-shrinkability) of a certain component resin layer.
