Title:
MOLDING PACKAGING MATERIAL AND BATTERY CASE
Document Type and Number:
WIPO Patent Application WO/2012/133683
Kind Code:
A1
Abstract:
Provided is a molding packaging material that can have an increased use life, can suppress a decrease over time in inter-layer lamination strength, and has superior molding properties in extrusion molding, draw forming, and the like. The laminate molding packaging material contains: an outside substrate layer (2) comprising a heat-resistant resin; an inside sealant layer (3) comprising a thermoplastic resin; and a metal foil provided between the two layers as a barrier layer (4). In the heat-resistant resin of the outside substrate layer (2), a biaxially oriented polyethyleneterephthalate film is used that, when the tensile breaking strength in the M direction is MB and the tensile breaking strength in the T direction is TB, the following are satisfied: formula (I) 500 MPa ≤ MB + TB ≤ 700 MPa; and formula (II) |MB - TB| ≤ 30 MPa.
