These pet waste bags are made from opaque green polyethylene sturdy enough to resist tearing during pickup and disposal. Each header pack holds bags that hang flat from two hooks inside a compatible dispenser, so a single bag can be pulled free without unwinding an entire roll. The header format is built to fit Crown Products dispenser stations and is also compatible with many other single-pull pet waste dispensers already installed in parks, trails, apartment complexes and other shared outdoor spaces. No tools or assembly are needed - the header simply loads into the dispenser housing before bags are pulled and used individually. The bags help facilities keep waste stations stocked so pet owners can clean up after their dogs without generating the extra packaging waste of a partially used roll.
