Blown film is actually tougher and has less of a chance of puncturing than cast film. This is caused by the slower cooling process that allows the blown film molecules to spread out instead of aligning as they do in cast film. Cast machine cast wrap has a glossier, clearer finish, which allows different scanning technologies to be used. Also, cast unwinds quieter and is easier to stretch than blown filmhttp://www.hongsince.com/glove-making-machine/
