The biodegradable cold cup is suitable for various production facilities, such as family tables, restaurants, parties, etc. It can be used to hold beverages of different temperatures, and will not deform like ordinary cups. But there is no need to worry about environmental problems when the biodegradable cold cup is used up, because the PLA material can be completely degraded by microorganisms in nature under certain conditions and does not pollute the environment, which is very beneficial to protect the environment.
