Abstract: Provided is a film which comprises at least a layer that contains, as a main component, a high-density polyethylene (A) which satisfies at least one requirement that is selected from the group consisting of requirements (a1) and (a2) described below. (a1) The high-density polyethylene (A) has a peak having a Full-Width at Quarter- Maximum (FWQM) value of less than 1.5 in a differential molecular weight distribution curve (horizontal axis: common logarithm value (LogM) of molecular weight (M), vertical axis: value dW/d(LogM) obtained by differentiating integrated concentration fraction (W) with respect to common logarithm value of molecular weight (M)) obtained by high-temperature gel permeation chromatography (GPC) measurement. (a2) The difference (LogM90 – LogM10) between the 90th percentile value (LogM90) and the 10th percentile value (LogM10) of the molecular weight distribution of the high-density polyethylene (A) in the differential molecular weight distribution curve is less than 1.25.
