Yes, all mentioned properties physical appearance; method of preparation

the film may be made of linear polymer, but also there are a lot of examples when covalently linked .

Hydrogels manly 3D covalently cross-linked polymeric structures swallen on water. although there are a lot of physically cross-linked hydrogels made of natural poloysacharides(alginate, chitosan) or synthetic PVA

films are mainly dry polymer
