A tear resistant multilayer film including pluralities of first and second layers is described. The first layers include a first polymer and the second layers include a second polymer. The first polymer is polyethylene terephthalate or a first ester block copolymer that includes polyethylene terephthalate blocks at a weight percent of the first ester block copolymer of at least 50 percent and further includes glycol-modified polyethylene terephthalate blocks. The second polymer is sebacic acid-substituted polyethylene terephthalate or a second ester block copolymer that includes sebacic acid-substituted polyethylene terephthalate blocks at a weight percent of the second ester block copolymer of at least 50 percent and further includes polyethylene terephthalate blocks or glycol-modified polyethylene terephthalate blocks. The tear resistant multilayer film includes a total of 6 to 300 first and second layers.
