What is the difference between an ordinary cup lid and a biodegradable coffee lid

A cup of hot drink can bring warmth and drive away the cold in winter. Some media reports that the material of the lid of these hot beverage cups is polystyrene, which will release styrene monomer when heated, and styrene monomer may cause a decrease in immunity and increase the risk of cancer.
 

Therefore, we have collected some information about the lid of the hot drink cup and discussed its safety with you.
 

Ordinary hot drink cup lid type：
 

There are generally two types of lids for hot drinks on the market: one is a straw type, and the other is a direct-drinking type. The straw type has pre-opened holes for drinking through the straw. The direct-drinking type has a drinking port and can be drunk directly through the lid of the cup.
 

Ordinary hot drink cup cover material：
 

At present, the hot drink cup lids on the market are mainly made of polypropylene (PP) and polystyrene (PS), and the material of the hot drink cup lid that has been reported to be carcinogenic is polystyrene (PS).
 

Styrene monomer is a kind of aromatic hydrocarbon, which is an organic compound formed by replacing one hydrogen atom of ethylene with benzene. The raw material for the production of polystyrene, styrene is a toxic and hazardous substance. The tentative maximum allowable daily intake of styrene established by JEFCA is 0.04 mg/kg. For a person weighing 60 kg, the maximum allowable daily intake is 2400 micrograms.
 

However, in assessing the risk of a substance, in addition to its toxicity, it also needs to consider the amount of its migration into the food.
 

Therefore, during the normal drinking of hot drinks, the risk of styrene migration from the lid of the cup into the food is very low.
 

The number on the lid of the hot drink cup：
 

There have been media reports before that the numbers on the lid of the cup contain plastic quality and safety information. In fact, these numbers are just codes for plastic materials.
 

For the understanding of the above traditional cup lids, you can then learn about our biodegradable coffee lids, which are made of sugarcane and are made of green and environmentally friendly degradable cup lids.
 

Green Olive Environmental Technology Co., Ltd., the eco-certified compostable coffee cup lid, is not just a cup lid, this is Ecolid made from biodegradable sugarcane pulp, a compostable hot coffee cup lid made of biodegradable materials.
