I think that's one of the challenges. Not all plastics are created equal. Again, in our industry, we rely significantly on a subset of plastic materials. One example is the PET resin that's used commonly in water bottles and food applications. It's used extensively as a rigid plastic, notably for produce clamshells.
There are other forms of plastic used—more flexible forms. An example that is pretty critical to our industry is modified atmosphere packaging. Those are the bags you see used for salad. It's a fairly complex construction that controls the environment within the bag to make sure the food doesn't spoil rapidly and maintains quality. These are examples of how we rely on a set of different materials, which, from the consumer point of view, may appear to be the same but are actually quite chemically different.
