Abstract

A multi-layer polyethylene film is a multi-layer polyethylene film comprising at least three layers of a first layer, a second layer, and a third layer in this order, wherein the softening point of the second layer is higher than the softening point of the first layer and higher than the softening point of the third layer, a ratio of the thickness of the second layer to the total thickness of the first layer and the third layer is 1 to 3, a temperature at the maximum of the melting peak observed in differential scanning calorimetry of the multi-layer polyethylene film is more than 129°C and less than 134°C, and an absolute value of the degree of molecular orientation of the multi-layer polyethylene film is less than 1.07.
