  About biodegradable paper cup
  The term "biodegradable" represents a process, but not necessarily under conditions or in a time frame, and the rate of decomposition can vary widely. Technically, all compounds can be biodegradable under the right conditions and will break down over a certain period of time, but that could be hundreds or thousands of years. For example, wood is biodegradable, but wooden structures don't break down and can be passed down from generation to generation. Trees are biodegradable but can live for hundreds of years.

The third kind is commonly used paper plastic cup, the outside is a layer of paper, there is a layer of film paper inside. The quality of the paper determines whether harmful substances will be produced during the use of the paper cup.

In addition to biodegradation, polylactic acid products have good biocompatibility, gloss, transparency, hand feel and heat resistance, as well as certain bacteria resistance, flame retardant and uv resistance.
