Drawstring trash bags are made from high-quality and high-density polyethylene materials, which are easy to recycle or degrade after use. Various raw materials with distinct performance characteristics are tightly integrated to create a multi-layer structure after utilizing multi-layer co-extrusion technology. This innovation not only can enhance the barrier performance and impermeability of garbage bags, but also effectively preventing liquid leakage. Besides, the unique drawstring design enhances convenience by sealing. With a simple pull, the bag opening can be tightened effortlessly.
