Wherein the foam sheet has an apparent density of 45 to 450 kg / m 3 , an average thickness of less than 0.03 mm and less than 0.3 mm, and a low density polyethylene having a low density polyethylene The dimensional change ratio in the extrusion direction when heated for 24 hours is from -5% to 0%, and the average thickness of the foamed film of the foamed layer is 6 to 70 μm. The foam sheet can be used as a separator for a glass plate. |
