To promote environmental protection, more and more people carry their own cups or pots; however, it will be a big mistake that distinguishing the heat-resisting degree by the number of cup bottom. Environmental Protection Agency (EPA) said that the number one to seven on the containers bottom is to identify the material of container for recycling; in other words, it doesn’t matter of the heat degree.
Department of Health which is in charge of food container also admitted that so far government doesn’t ask to labeling material and heat resistance on the products. Therefore, the costumers must find out the heat level of their carry-cups or pots in case drink with poison, or use stainless steel or alloy hot interior of the portable cup with lower health risk.
EPA will take a new measure that bringing your own cup to buy drinks could enjoy discounts to reduce the consumption of take-out disposable cups. Nevertheless, some early implementation of food dealer found that many people use no marked degree of material and heat –resistant plastic container to buy hot drinks. Costumers found the number of the container’s bottom, but how high the temperatures the container can stand still don’t know.
EPA Recycling Fund Management Board said the number one to seven under the containers is internationally accepted fact, “recycling signs,” represents the material. For example, number five is polypropylene (pp) melting point of one hundred sixty –seven degree Celsius temperature; hence, container made by polypropylene can stand to one hundred degree Celsius temperature without safety concern for ordinary hot drinks. V can stand high temperature, but if it was made with thin blowing or adding other plastic material for the appearance, resulting in lower heat resistance that may not be able to install the hot drink.
