What are the safety knowledge of biodegradable coffee lids

In the cold winter, a cup of hot drink can bring warmth and drive away the cold. However, there have been media reports before 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 on the lid of the hot drink cup and discussed its safety with you.

1. About the type of hot drink cup lid

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

2. About the material of hot drink cup lid

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

3. About 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 the codes for plastic materials.

Regarding the understanding of these traditional cup lids above, 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.

We are the manufacturer of biodegradable lids. If you have any questions or need to purchase, you can contact us.
