Venrich is a bottle top filter product. It is a new interpretation of the disposable bottle top filter. Funnels are mainly made of polystyrene, but Venrich is made of polypropylene, so it does not break easily and has excellent chemical and heat resistance. Most importantly, since the welding process is excluded, the membrane and plastic housing can be easily separated. After using the bottle top filter, the customer can separate the membrane and plastic housing, discard only the membrane as bio-medical waste, and swipe the remaining plastic and process it as recycled plastic. The plastic PP recycled in this way can be reused, and the final new product uses recycled PP chips to become a product with excellent ESG value that utilizes circular resources.
