Hey @Laura C - I can't speak to packaging products in wax paper or glassine bags. I only package my products in polypropylene bags. When you refer to packaging different scents together in the same bag, do you mean individually packaged or unwrapped? I package all products individually or multiples of the same scent in a single polypro lined bag. However, I will store similar scents together in a storage container and do ship different scented products together (in one order), in a single polypro bag, but they are individually wrapped and labeled. To date, I've never had any scent morphing via absorption when done this way. Hope this helps.
