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.
Claims13
An extruded resin laminate, comprising a plurality of resin species and having two major surfaces and a thickness defined between the two major surfaces,
- wherein layers of said plurality of resin species are laminated parallel to the major surfaces in a section across the thickness in an extruded machine direction and laminated obliquely at an inclination angle of at most 4 degrees with respect to the major surfaces in a section across the thickness in a transverse direction perpendicular to the extruded machine direction, and
- each layer of said plurality of resin species is exposed to the two major surfaces to form a pattern of surface stripes of said plurality of resin species running parallel to the extruded machine direction.
