Other plastics are most often made of multiple resins or layers of different types of plastics. Some examples are polyamide, acrylonitrile butadiene styrene (ABS), acrylic, nylon, polyurethane (PU), and phenolics. They may be used to make things such as microwavable packages, snack bags, and many industrial plastics. These items are difficult to recycle and alternatives should be sought.
