Secondary battery metal terminal coating resin film, method for manufacturing same and battery pack

A secondary battery metal terminal coating resin film, comprising:

• a laminated structure that is capable of coating a metal terminal connected to a positive electrode or a negative electrode of a secondary battery, and,
• wherein the resin film has three layers including a core layer as an intermediate layer of the resin film and skin layers as other layers of the resin film, and,
• wherein a difference of a melt flow rate between the core layer and the skin layers is within a range from about 5 g/10 minutes to about 30 g/10 minutes.
