Disposable tableware is divided into the following three categories according to the source of raw materials, production technology, degradation method and recycling level:
1. Biodegradable products: such as paper products (including pulp molded products, cardboard coated film), food powder molded products, plant fiber molded products, etc.
2. Photobiodegradable materials: photobiodegradable plastics (non-foaming), such as photobiodegradable PP;
3. Recyclable materials: such as polypropylene (PP), HIPS, bidirectional tensile polystyrene (BOPS), and polypropylene composites filled with natural inorganic minerals.
