Does the PP injection molded cup emit odor when in use?

PP injection molded cup, also known as polypropylene injection molded cup, is a widely used tableware, and its material properties give it many advantages. Polypropylene itself is a non-toxic, odorless plastic material with excellent chemical corrosion resistance, heat resistance and high wear resistance, which makes PP injection molded cups very popular in daily life and the catering industry.
During the production process, qualified PP injection molded cups will strictly abide by the relevant food safety standards and production specifications to ensure that no substances harmful to the human body, such as plasticizers, are added. Therefore, under normal circumstances, PP injection molded cups will not emit any odor.
However, although the PP injection molded cup itself has the characteristics of odorlessness, it may still produce odor in certain specific circumstances. For example, if the PP injection molded cup is not properly stored during storage, it may be affected by moisture or other forms of contamination, which may cause odor. In addition, long-term use, especially after being used to hold perishable foods such as high sugar and high fat, if it is not cleaned thoroughly in time, it may also cause bacteria to grow, thereby producing odor.
In the face of the odor problem that PP injection molded cups may produce when in use, we can take some effective measures to remove it. First, place the cup in the sun or a well-ventilated place for drying. This is a simple and effective method to help the odor volatilize. Secondly, activated carbon is widely used to remove odors due to its strong adsorption. We can place the activated carbon bag near or inside the cup to absorb the residual odor.
In addition, we can also use some acidic substances to neutralize odor molecules. For example, diluted white vinegar or lemon juice are both good choices. After wiping the plastic surface with these acidic substances and then washing it with clean water, it can not only remove odors, but also give the cup a fresh smell. Of course, there are also professional plastic odor cleaners available on the market. These cleaners usually contain ingredients that can decompose odor molecules, and they can achieve a thorough deodorization effect when used according to the instructions.
