What is different between PP, PS, ABS plastic material used to manufacture pill box?
They are food grade plastic material. But they have different feature and usage in our item. We use PP to produce a lot of our item, they are easy to shape, one-piece molding, not dissolve in essential oils. PP is transparent but not as clear as PS. PP is strong and pressure resistant but not as strong as ABS. PP has very balance characteristic between PS and ABS.
