If you use one with a zero particle size larger than 50 μm, preferably 30 μm or less,
When formed into a film, the particles of aluminum sulfate stand out, giving it a rough and undesirable appearance.As a base material for the synthetic resin film, any thermoplastic synthetic resin that can stably decompose aluminum sulfate can be used. For example, high density polyester, low density polyethylene, polypropylene, polyvinylidene chloride, polyvinyl acetate, polyamide, etc. can be selected.
