What are the materials of disposable plastic milk tea cups that are usually used?

With the continuous development of technology, plastic cups have become more and more serious, and the international community is calling for environmental protection. First of all, we must first understand the materials of the disposable plastic milk tea cups we usually use? Here I will briefly introduce the materials used in the tea cups produced by the factory, such as PP material, pet material and ps material. For the future technological development, if these materials can be degraded, it is a great benefit to the environment. Degradable plastic refers to a plastic that is added to a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradation agent, etc.) in the production process, which has reduced stability and is easily degraded in the natural environment. The photosensitizer is incorporated into the plastic to gradually decompose the plastic under sunlight. It belongs to the earlier generation of degradable plastics. The disadvantage is that the degradation time is difficult to predict due to sunshine and climate change, and thus the degradation time cannot be controlled. A plastic that can be completely decomposed into a low molecular compound by the action of microorganisms. The utility model has the advantages of convenient storage and transportation, as long as it is kept dry, does not need to be protected from light, and has wide application range, and can be used not only for agricultural mulch films and packaging bags, but also widely used in the medical field. With the development of modern biotechnology, biodegradable plastics have received more and more attention and have become a new generation of research and development hotspots.
Under normal circumstances, the plastic milk tea cup is filled with milk tea to keep fresh or frozen, and the cup will not break without ice. The customer told us that in other manufacturers, the tea cups in the refrigerators and the milk cups were not cracked. The reason is only one, that is, the pp material used by the manufacturer in the production of the cups is recycled materials, not new pp materials. The recycled material is also the second-hand material. The produced cup is not strong and brittle, and it will crack when the temperature is low. The milk tea cup produced by the normal new pp material will not have a cracking effect without icing.
